A careful examination of the third volume of this work serves to sustain the favorable opinion expressed in regard to the preceding volumes. The present volume covers constitutional diseases, the respiratory, digestive, nervous and muscular systems and mental diseases. The surgical treatment of the various regions involved is also discussed. Thus we have articles on the surgery of the infectious diseases of the lungs and pleura, the surgical treatment of visceroptosis, surgical treatment of diseases of the spinal cord, etc.
In general the treatment is excellent. There are some indications of insufficient editorial control. Thus it is stated (p. 126): "The pollantin which was imported into this country previous to the present year was made from grasses and therefore should theoretically be of no value when used to prevent or control hay-fever produced by the ragweed or goldenrod." This statement must refer to 1905 or 1906 and not to 1010,
