Illustrated Medical Dictionary 



The acid test of a medical dictionary is its neiv word service — 

 its unfailing and quick response to your search for the meaning 

 of new words. The American Ilhistrated Medical Dictionary 

 is newer by one year than any other medical dictionary on the 

 market. For that reason alone it defines hundreds of new words 

 not in any other lexicon. Take, for instance, those words intro- 

 duced into medical literature by the war. Can you find these 

 war words and war abbreviations in any other medical dictionary? 



As in war words, so it is in every branch of medical science. The new 

 words are here — 2000 of them — hundreds not to be 

 found ill any other dictionary. If you are considering 

 buying a new dictionary — and only a new one will give 

 you real service — by all means put The American Illus- 

 trated Medical Dictionary to the test.
