This volume contains very little as to the diagnosis of tuberculosis, but emphasizes particularly the types of immunity and immunologic reactions in tuberculosis and gives a new method of treatment, based largely on the use of "partial antigens." Many new ideas are advanced, which make the book most interesting. The author adheres to the old idea that erythema nodosum is a tuberculid, to which the reviewer takes exception. The translator, at least, makes the common mistake of using the words "tubercular" and "tuberculous" synonymously. The book should be read by all students of immunology and by those particularly interested in the treatment of tuberculosis.
