Differences in reaction to toxic substances vary considerably between species so that the value of these tests remains doubtful. Although thalidomide was extensively tested on animals in several countries, its terrible properties were not discovered. Conversely, penicillin, the greatest medical discovery of the century, was not extensively tested on animals before its miraculous therapeutic qualities were demonstrated in human patients. If it had been fully tested on animals its high toxicity for guinea pigs would have almost certainly prevented its clinical use.

Misleading may be the claims that procedures [of animal testing] are carried out under anaesthesia. Restraining devices and paralysing drugs can today be so effective that an anaesthetic is often unnecessary from the purely practical point of view. The risk of giving a dose too large and thereby losing an expensive chimpanzee, for example, may often tempt a scientist or technician, inexperienced with sophisticated anaesthetic techniques, to give a dose too small, from which the animal quickly recovers — but not of course until after it has been strapped securely to the operating table.
