Excerpt from Vaccine and Serum Therapy in Veterinary Practice In writing this small volume I have endeavoured to explain the phenomena of immunity and make the explanation as clear of conception as possible. My chief object in producing this work is that it may be a small means of stimulating the veterinary practitioners of this country to take greater advantage of the modern means of treating disease by the various biological products now at their disposal. In this branch of medicine we hold a distinct advantage over the medical profession, inasmuch as we have a greater freedom in applying biologics in the treatment and diagnosis of the various diseases to which the domesticated animals are subject; also in serum treatment we have the advantage that the serum employed is very often obtained from the same species of animal as the one on which we are employing it. In other words, the serum is homologous. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
