'Vivisection' is a collection of essays written by Albert Tracy Leffingwell. The topic discussed in this essay is one Leffingwell holds dear: vivisection form. Throughout his life, Leffingwell, who was a physician, authored many books bringing light to the cruel abuses of animal experimentation and calling for regulation. At the same time, he sought a middle ground between the anti-vivisection societies, which called for the abolition of all experimentation and those who rejected any restraints.
