Connaught Biosciences accepts takeover offer
Engineer at Jet Propulsion Lab readies Galileo spacecraft for tests
tains much of its original chemical nature—unlike Earth and the other planets, which have lost much of their light constituents. Researchers hope, thus, to gain greater understanding of the solar system's origins. The planet is about 318 times the size of Earth and has at least 16 satellites. Current models picture a deep and dense atmosphere, primarily composed of hydrogen and helium in about the same concentrations as in the Sun. A small, rocky core with the mass of a few Earths may exist at the center.
The orbiter carries 10 scientific instruments. They are a camera system, a near-infrared mapping spectrometer, an ultraviolet spectrometer, a photopolarimeter radiometer, a magnetometer, a plasma instrument, an energetic-particle detector, a plasma-wave instrument, a dust detection instrument, and radio science instruments.
The probe bears six instruments: an atmospheric structure instrument, a neutral mass spectrometer, a helium abundance interferometer, a nephelometer, a net flux radiometer, and a lightning and radio emission instrument.
Galileo has a "launch window" with a favorable conjunction of planets lasting from Oct. 12 to Nov. 21. The next window will be in 1991.

Connaught Biosciences Inc., Toronto, a biotechnology company that produces mainly vaccines, has accepted a takeover offer of $31.45 per share ($1.00 = $1.18 Canadian) from Institut Merieux, a biologicals company based in Lyons, France. Ciba-Geigy and Chiron Corp., in a joint venture , made an offer of $25.50 per share only two weeks ago. At that time, Institut Merieux and Connaught had already agreed on a merger. With the backing of Rhône-Poulenc, which owns 50.3% of Institut Merieux, the company was able to come up with the higher cash offer.
Institut Merieux already owns 2.75 million shares of Connaught and will pay slightly more than $800 million for the remaining 21.9 million shares and additional securities. A Merieux spokesman says the purchase debt will be reduced through a sale of up to 49% of the new company's shares. Combined 1988 sales of the two companies
exceeded $700 million. Ciba-Geigy, which owns 10% of Connaught, has not yet decided on its response to Merieux's offer.
Connaught was originally owned by the University of Toronto. It was sold in 1972 to Canada Development Corp., and later spun off as a public company. The university, currently involved in collaborative research projects with the company, has filed a suit against the firm, based on an agreement from 1972 that would block takeover by a foreign buyer.
Institut Merieux will also have to fulfill several commitments required by the Canadian government. These include the construction of a $25 million to $35 million biotechnology R&D and production facility in Canada in the next five to seven years. Connaught 's Bio-Research Laboratories Ltd. and its 35.4% interest in Nordic Laboratories Inc. are expected to be sold.

New satellite data from the National Aeronautics & Space Administration show that stratospheric ozone above Antarctica is being destroyed at a rapid rate. The pattern of ozone depletion is very similar to 1987, the worst year to date.
