the skin of the belly and punctured it with a quick down thrust of the hypodermic needle. The pig gave a little jerk, a little squeak, and the co-eds shuddered. Gottlieb's wise fingers knew when the peritoneal wall was reached. He pushed home the plunger of the syringe. He said quietly, "This poor animal will now soon be dead as Moses." The class glanced at one another uneasily. "Some of you will think that it does not matter; some of you will think, like Bernard Shaw, that I am an executioner and the more monstrous because I am cool about it; and some of you will not think at all. This difference in philosophy iss what makes life interesting."
While the assistant tagged the pig with a tin disk in its ear and restored it to the battery jar, Gottlieb set down its weight in a note-book, with the time of inoculation and the age of the bacterial culture. These notes he reproduced on the blackboard, in his fastidious script, murmuring, "Gentlemen, the most important part of living is not the living but pondering upon it. And the most important part of experimentation is not doing the experiment but making notes, ve-ry accurate quantitative notes—in ink. I am told that a great many clever people feel they can keep notes in their heads. I have often observed with pleasure that such persons do not have heads in which to keep their notes. This iss very good, because thus the world never sees their results and science is not encumbered with them. I shall now inoculate the second guinea pig, and the class will be dismissed. Before the next lab hour I shall be glad if you will read Pater's 'Marius the Epicurean,' to derive from it the calmness which is the secret of laboratory skill."
As they bustled down the hall, Angus Duer observed to a brother Digam, "Gottlieb is an old laboratory plug; he hasn't got any imagination; he sticks here instead of getting out into the world and enjoying the fight. But he certainly is handy. Awfully good technique. He might have been a first-rate surgeon, and made fifty thousand dollars a year. As it is, I don't suppose he gets a cent over four thousand!"
Ira Hinkley walked alone, worrying. He was an extraordinarily kindly man, this huge and bumbling parson. He reverently accepted everything, no matter how contradictory to everything else, that his medical instructors told him, but this
