Chicks are so accessible, so easily fed and observed, so much drier to handle and measure, that for his purpose tadpoles seemed to him now, in comparison with them, quite wild and uncontrollable beasts. He was quite puzzled to understand why he had not thought of chicks instead of tadpoles from the beginning. Among other things it would have saved all this trouble with his cousin Jane. And when he suggested this to Redwood, Redwood quite agreed with him.

Redwood said that in working so much upon needlessly small animals he was convinced experimental physiologists made a great mistake. It is exactly like making experiments in chemistry with an insufficient quantity of material; errors of observation and manipulation become disproportionately large. It was of extreme importance just at present that scientific men should assert their right to have their material _big_. That was why he was doing his present series of experiments at the Bond Street College upon Bull Calves, in spite of a certain amount of inconvenience to the students and professors of other subjects caused by their incidental levity in the corridors. But the curves he was getting were quite exceptionally interesting, and would, when published, amply justify his choice. For his own part, were it not for the inadequate endowment of science in this country, he would never, if he could avoid it, work on anything smaller than a whale. But a Public Vivarium on a sufficient scale to render
