Hating religion, which was a constant rebuke to all he loved best, he threw himself with renewed zest into the pursuit of science, which was too cold to reproach him with anything, and he determined to win respect for services rendered to physiology which he could scarcely hope could be conceded for anything else within his reach. He was not loved; he determined to be respected. Soon he found his opportunity. A skilful and patient worker at the microscope, he earned much favour and profit from Mr. Crowe by his admirable pathological work. Many thousands of beautiful sections and other objects in the microscope room were the result of Mr. Mole’s deft labours in this direction. He became indispensable in the physiological room, and the constant attendant on the researches of his master. There was a common sentiment which drew these men together. Both feeling that the world did not love them for themselves sought to compel admiration for their achievements. Both were essentially cruel at heart; both would not only have gladly botanized on their mother’s graves to discover anything to win them credit, but would have learned with pleasure anything they could from the sufferings of their dearest relations. Mr. Mole took care that his chief never ran short of dogs, rabbits, guinea pigs, mice, or frogs, for use at the tables and troughs. To show his devotion to this work he even gave up a worn-out retriever which had saved his life a few years before by arousing him from sleep when his chamber was on fire. What greater proof of devotion to one’s work could be demanded than this? But he would have done even more to win favour with Mr. Crowe. Had he not been introduced by him with high encomiums to several learned medical societies, and had not his early attempts at writing for the scientific journals been aided by his counsel? Such a friend was worth a dog or two. He laboured at first, above all things, to win Mr. Crowe’s favour; then, as the work began to be familiar, he embraced it with an ever-increasing love. It did not give Mr. Mole much difficulty to rid himself of the outside prejudice against causing needless suffering to sentient beings, though when he first began, it was not with the “true spirit of the artist” that he approached his work. But this came in time, and now not alone on Mr. Crowe’s account, but for its own sake, this laboratory business took hold of every fibre of his being. He revelled in it; he spent in it his nights as well as his days. His Sundays were specially devoted to the more private, revolting, and awful exercises which Mr. Crowe would only share with priests of the inner temple of science. Here one vied with another who could do the most startling things, who could invent newer forms of torture. CHAPTER XX. THE PROFESSOR AT HIS WORK.
