PLEGIA ; COMA; GLYCOSURIA ; DEATH.H. N--, aged thirty-eight, married, was admitted on

May 22nd, 1S80, at 11.30 P.m. He was very pale, his skinwas cold and moist, and his pulse was weak ; he was de-lirious, and complained of intense pain in his head. No traceof hemiplegia could be discovered, the patient walking intothe ward with the assistance of his friends. The pupilswere normal. He was put to bed, and an ice-bag wasapplied to his head. Shortly afterwards there was somevomiting.At half-past one the next morning he became very violent

.and noisy ; at five o’clock he was comatose, and at seven hewas dead. Some urine was drawn off by the catheter, andfound to contain sugar. It was ascertained from his friendsthat he appeared to be in perfect health up to the day ofhis admission ; that he had spent that day at some pleasure-gardens, and had had no alcohol beyond three glasses ofbeer ; that he was about to start for home when he suddenlycomplained of severe pain in his head, and shortly after-’wards became temporarily unconscious on his way to theinfirmarv.At the necropsy a dark clot was found, filling the lateral,

third, and fourth ventricles of the brain ; blood was effusedover the base of the brain, and had extended upwards overthe surface of the hemispheres, filling the sulci. The largeganglia and other important structures at the base of thebrain were uninjured. No ruptured vessel or aneurism wasdiscovered. The lungs were emphysematous. The heart,liver, spleen, kidneys, and other organs were healthy.There were no marks of external violence.

Reviews and Notices of Books.The Utricular Glands of the Uterus, &c. By Prof. ERCOLANI.

Translated under the direction of H. O. Marcy, A.M.,M.D. Triibner and Co.

THE work of Professor Ercolani has been long known in itsmain feature to those who have followed the researches whichhave been recently made into the structure of the placenta ;for although the title of the work would scarcely lead oneto expect it, yet the main object of the author is to prove aview which he has been led to adopt of the structure andfunction of the placenta, while the description of the utricu-lar glands of the uterus forms but a part, though a verynecessary part, of the evidence which the author producesin support of his theory. This theory is as follows :-" There is produced in the pregnant uterus of mammals, in-cluding the human species, a glandular organ of new forma-tion. This organ constitutes one of the two fundamental

portions of the placenta, that is to say, the maternal

portion, with which the fcetus is brought into intimate con-tact by the villi of the chorion, which composes the otherportion of it, or the foetal part. The villi of this latter

part of the placenta penetrate always and obviously intothe glandular organ or maternal part, in order to absorb thefluid which is there secreted, and thus to furnish the foetuswith the materials necessary for its nutrition."With a view to establish this theory the author gives an

account of " the utricular glands in mammalia, in the gravidand non-gravid animal," their development and function;he points out their increase of size in the gravid state,and adopts the opinion of Eschricht that these glands,together with the simple follicles, " elaborate, during gestil-tion, a fluid destined to furnish some elements for the nutri-tion of the fœtus, narticularlv when the organs which arE

charged with that office, or the villi of the chorion, are notfully developed." The human decidua, it is paid, "maybe considered as a product of exudation, due for the mostpart to the utricular glands, and the numerous openingswhich perforate it obliquely precisely indicate the mouths ofthese g’ands, which remain open in the decidua for the con-

tinual passage of the materials elaborated by the glands."In accordance with this view the author explains the forma-tion of the decidua reflexa. He states : "Now if, accordingto the preceding observations, the uterine or true decidua isonly a product of exudation, due in great measure to thesecretion of the uterine glands and to the transudation oforganisable fluids from the internal surface of the uterus, itbecomes easy to comprehend the formation of the reflecteddecidua. While the whole internal surface of the uterusis covered with the uterine decidua, the ovum when

reaching the uterus is also covered with a similar layer,formed by the same materials, which further serve to fix itat one point of the uterus. At this point the uterine andthe reflected deciduse are soon mingled together, precisely aswill take place later, when the ovum, increasing in size,forces the reflected decidua which surrounds it against theuterine decidua, so that the two deciduæ blend into one

single membrane." The serotina again is described as

follows :-" This membrane, produced by the proliferationof the cells of the superficial or submucous connective tissueof the uterus, is the stroma whence originates the glandularorgan which supports and envelops the villi of the fœtal

placenta in all their subdivisions." The author never tiresof emphasising his view that the maternal part of the

placenta is a new formation, owing " its origin in the humanspecies to the new formation of special cells, which in thehuman species has received the name of decidua serotina."It has nothing to do with the glandular structure of the un-impregnated uterus. Indeed, Ercolani maintains that a

" primordial destruction, more or less marked, of the uterinemucous membrane, is indispensable for the beginningand completion of the new formative process, from which,in all cases, results the development of the maternal portionof the placenta." Finally, it is held that the nutrition ofthe fcetus is not maintained by osmotic processes betweenthe blood of the mother and that of the fcetus, but by

. absorption by the epithelium of the chorion villi of a fluid

. secreted by the cells of the serotina, which cover the chorion

. villi. and this is the case. however intimate the union mavbe between the fcetal and maternal parts of the placenta. Itshould be stated, further, that the author accepts the viewthat the placenta contains large sinuses possessing thinwalls, and that these thin walls cover the foetal villi in alltheir parts, and are closely united to them ; that the bloodof the mother is passed into these sinuses in its course fromthe arteries to the veins.

It would be impossible to enter here into the details of thedescriptions of the placenta of various animals and of thehuman species found in this work. We can only notice someof the main conclusions arrived at by the author. Withreference to the manner of nutrition of the foetus by absorp-tion of secreted material rather than by osmosis, our

knowledge does not warrant any positive statement. The

question is an extremely difficult one. There is greatprobability that such is the mode before the formation of theplacenta ; but the evidence brought forward in the workbefore us fails to prove such to be the case after tLatoeriod.

I The term " mucous membrane" is used in a peculiarsense by the author, for he says, "In woman ... , the

simple epithelial layer, which by itself represents all themucous membranes of the uterus, ..." Now this useof the term is one not generally accepted, and is, moreover,one which gives to the views promulgated a much morestartling character than they really deserve, but fur positivestatements made by him (and quoted above) with regar ! the nature of the deciduæ and serotina. lu the destructive

The Archiveswill deal principally with nosography and records of clinicalobservation, but will also embrace normal and pathologicalanatomy and physiology, experimental and therapeuticalresearches. This first number contains articles bearingupon almost every one of these departments. Thus,under the head of anatomy we have a short paperby Debove and Gombault upon the decussation of sensoryfibres in the medulla. The point was settled by theexamination of the medulla in a case of lateral amyo-trophic sclerosis ; and they clearly show that afterdecussation the sensory filaments mingle intimately with themotor fibres of the pyramids. A short note by M. Debove onthe preparation of the spinal cord for microscopical examina-tion follows. He keeps the cord for three weeks or longerin a 4 per cent. solution of bichromate of ammonia, then forthree days in a carbolised gum solution, then for three daysin alcohol. The sections made and the gum washed out,they are left for twenty-four hours in a saturated solution ofpicric acid, after which they may be readily stained withcarmine. This process has yielded him better results thanany other. Under the heading of Experimental Pathologi-cal Anatomy there is the first instalment of an investigationby M. Gombauit upon the nerve-changes in subacute andparenchymatous neuritis. He has studied these lesions in

guinea-pigs slowly poisoned by lead, and describes and

figures degeneration and disappearance of the myelin limitedto different segments of the nerve fibre in this condition ;and he further illustrates the lesion by changes similarly ob-served in muscular atrophy and traumatic neuritis in man.Under Pathology there is an article by M. Debove andM. Boadet de Paris upon the Motor Inco-ordination of

Ataxics, where they attempt to prove, chiefly by means ofthe use of the "myophone," that inco-ordination is due tounequal tonicity of the muscles, and that its effects are

diminished by their maximum contraction. Under MentalMedicine there is a lengthy and learned article by M. Mag-nan demonstrating the frequent co-existence of different kindsof delirium in the same insane subject; and the first part ofan interesting contribution to the clinical and pathologicalstudy of Idiocy by M. Bourneville. The section of Thera-

peutics is represented by the record of two cases of herni-plegia, in which motor power and sensibility were restoredby the use of magnets. This, again, is by M. Debove. Areview of present knowledge upon Cephalic Thermometryby M. Boyer follows ; and the closing pages of the journalare devoted to abstracts of recent published work in variousdepartments and to a few reviews of books. Altogether thenumber is full of interesting and readable matter, and if thejournal fulfil the promise of its first issue in subsequentnumbers, it will, no doubt, be widely read. The secondissue is to appear on October 1st, and, like our own publica-tion in the same field, Brain, it is to be published quarterly.


COWL.THE accompanying engravings represent one of various

types of the improved ventilator invented by Alfred Hall,M.D., F.R.C.P. London. Its main feature consists inan aggregation of four, six, or any other binary numberof tubes or oritices surmounting the soil-pipe or other con-duit from which foul air or fetid smells are emitted, and aglance at our illustrations shows that the object aimed at isattained without the use of any mechanical contrivance, orof any very intricate construction like those that form per-fect labyrinths in tome other ventilating arrangements.

Fig. 1 is a front view of the ventilator, representing thetwo orifices, B’ B", that adjoin one another; Fig. 2 is alongitudinal section, and Fig. 3 a horizontal section takenthrough the line &agr;-&bgr;, Figs. 1 and 2. A is the soil-pipe or

other conduit to be ventilated or disinfected ; it is in the

present instance surmounted by a system of six orifices, B B,closed up at the top by the helmet, c, and half trumpet-shaped at the bottom, as shown in section at b, Fig. 2. Thecurrent of air passes through the orifices B B, B’ B’, B" B",opposite one another, and a continuous exhaustion of thefoul air or noxious vapours is secured by this means.We have remarked that our illustrations represent but

one out of a number of types of the same ventilator, whichmay equally well be used as a chimney-cowl. Another typeis that of an ascending soil-pipe closed up at the top andsurmounted simply by a cross of four short horizontal tubes,through which the suction of the fetid air takes place. This

ventilator may be made of tinned iron or zinc plate, as wellas of copper or terra-cotta. There being no mechanical con-trivance or appliance of any kind connected with it, it is notlikely to evt-r get out of order ; and, if made of copper, it is

practically indestructible.
