Majendie was the founder of the School of Experimental Physiology, and was so indifferent to the sufferings of the animals experimented upon that he has been called cruel by his fellow workers, and was even accused of having performed experiments on human beings. On the occasion of his first visit to England he was openly accused in Parliament, but was so warmly defended by James Mackintosh and a strong party, that the accusation led to no result. “I recall to mind a poor dog, the roots of whose vertebral nerves Majendie desired to lay bare. The dog, already mutilated and bleeding, twice escaped from under the implacable knife, and threw his front paws around Majendie’s neck, licking him, as if to soften his murderer and beg for mercy. Vivisectors may laugh, but I confess I was unable to endure the heartrending spectacle.”--Dr. Latour, Lancet, No. 2,086, pp. 224-5. =Malassez=, 168, Boulevard Saint Germain, Paris, M.D., 1873. Asst.
