 Why was Ferris against testing the discovery made by himself and Mitchell on himself?

Who would have financed a study of cyclic periods of the hedgehog? "When we prove our results that should be of enough practical value for anyone. Our reputations don't go outside our own fields," Mitchell said. "But now Macklin—" Elliot Macklin had inherited the reputation of the late Albert Einstein in the popular mind. He was the man people thought of when the word "mathematician" or even "scientist" was mentioned. No one knew whether his Theory of Spatium was correct or not because no one had yet been able to frame an argument with it. The government took up a lot of his time using him as the symbol of the Ideal Scientist to help recruit Science and Engineering Cadets. For the past seven years Macklin—who was the Advanced Studies Department of Firestone University—had been involved in devising a faster-than-light drive to help the Army reach Pluto and eventually the nearer stars. Mitchell had overheard two coeds talking and so knew that the project was nearing completion. "He's always treated me like dirt," Ferris said heatedly. He looked more than a little like a postgraduate student, and Mitchell suspected that that was his intention. Macklin threw a big arm across Ferris' shoulders. "Doctor, we understand you have severe headaches," Mitchell said. "Everybody has them at some time in his life. "But think," Ferris interjected, "what a boon it would be if everyone could be cured of headaches forever by one simple injection." "Aspirins would still be used to reduce fever and relieve muscular pains," Mitchell said. "There are a number of different causes for headaches—nervous strain, fatigue, physical diseases from kidney complaints to tumors, over-indulgence—but there is one effect of all of this, the one real cause of headaches," Mitchell announced. "We have definitely established this for this first time," Ferris added. "The pressure effect caused by pituitrin in the brain," Mitchell said eagerly. "The virus," Ferris explained, "can easily be localized and stabilized. A colony of virus in the brain cells will relax the cerebral vessels—and only the cerebral vessels—so that the cerebrospinal fluid doesn't create pressure in the cavities of the brain."
 Because it was unethical.
 Because it was too dangerous.  Because it was unethical.  Because he had a headache.  Because they were underfunded.
