The increasing activity in research medicine in America becomes apparent in the number of monographs published during recent years. This most recent addition to the list summarizes the careful reading as well as the more recent work of the members of the Sprague Institute interested more particularly in tuberculosis. The publishers state that it is a complete reference handbook on the chemical aspects of tuberculosis and related problems. It is that. The material is quite recent, the presentation is well balanced, and seemingly nothing of importance has escaped consideration. It is invaluable to the worker in tuberculosis.
It is certainly refreshing and perhaps significant to note that the term "antibody" finds no place in the index. We are apparently advancing in our knowledge of tuberculosis when speculation gives place to accurate observation of biochemical and biophysical processes.
