RT Journal T1 HAndbuch der pathogenen mikroorganismen. JF Journal of the American Medical Association JO Journal of the American Medical Association YR 1929 FD February 16 VO 92 IS 7 SP 583 OP 583 DO 10.1001/jama.1929.02700330067037 UL http://dx.doi.org/10.1001/jama.1929.02700330067037 AB The three articles in this issue are admirable examples of the best German scientific scholarship. Each in its way is a masterly exposition of the subject treated. In the article on chemotherapy, the clarity of arrangement and the frequent and extensive use of tabular summaries render the article peculiarly valuable to the active worker. The discussion of epidemiology by Kisskalt brings together in compact form a number of scattered observations and, while not doing full justice to the wealth of material gathered by other than German writers, particularly that from British sources, is nevertheless a generally fair and comprehensive summary. The somewhat threadbare subject of the general prophylaxis of the infectious diseases is skilfully and even freshly handled by Gotschlich. The characteristic national emphasis on the potency of official regulations is, however, not lacking.
