A wealth of scientific information that French medicine has to offer can properly be grasped by those who are able to be in constant touch with the literature in its original language. The monumental work of the individual investigators in each chosen specialty is overwhelming by its profound erudition. The accumulated data during the recent war prove amply that the power of observation in its accuracy and precision as revealed by French scientists deserves special attention. To those who are willing to follow up closely the progress in French medicine in the original writings the present Dictionary is offered. Also, those who since the cessation of hostilities have decided to continue the study of the language will find in the Dictionary a means of learning its proper pronunciation. Each French word is accompanied by a combination of letters in English giving the pronunciation as accurately as possible. On a separate page a key for the latter is added & should be consulted frequently.
