The first horrible incident of our acquaintance was the greatest shock I ever experienced, and it is only with reluctance that I repeat it. As I have said, it happened when we were in the medical school, where West had already made himself notorious through his wild theories on the nature of death and the possibility of overcoming it artificially. His views, which were widely ridiculed by the faculty and his fellow-students, hinged on the essentially mechanistic nature of life; and concerned means for operating the organic machinery of mankind by calculated chemical action after the failure of natural processes. In his experiments with various animating solutions he had killed and treated immense numbers of rabbits, guinea-pigs, cats, dogs, and monkeys, till he had become the prime nuisance of the college. Several times he had actually obtained signs of life in animals supposedly dead; in many cases violent signs; but he soon saw that the perfection of this process, if indeed possible, would necessarily involve a lifetime of research. It likewise became clear that, since the same solution never worked alike on different organic species, he would require human subjects for further and more specialised progress. It was here that he first came into conflict with the college authorities, and was debarred from future experiments by no less a dignitary than the dean of the medical school himself—the learned and benevolent Dr. Allan Halsey, whose work in behalf of the stricken is recalled by every old resident of Arkham.
