Memories and Studies

“Well,” said the predecessor, apologetically, “to tell the truth, whenever I used that machine I found it advisable to drive a nail through the centre of gravity.” I once saw a distinguished physiologist, now dead, cheat most shamelessly at a public lecture, at the expense of a poor rabbit, and all for the sake of being able to make a cheap joke about its being an “American rabbit” — for no other, he said, could survive such a wound as he pretended to have given it. To compare small men with great, I have myself cheated shamelessly. In the early days of the Sanders Theater at Harvard, I once had charge of a heart on the physiology of which Professor Newell Martin was giving a popular lecture. This heart, which belonged to a turtle, supported an index-straw which threw a moving shadow, greatly enlarged, upon the screen, while the heart pulsated. When certain nerves were stimulated, the lecturer said, the heart would act in certain ways which he described.
