the list when Dr. T. B. McClintic of the United States Public Health 

 Service died in Washington after having contracted Rocky Mountain 

 spotted fever while investigating the disease in Montana. Dr. McClin- 

 tic was regarded as the leading authority on this disease. 



A man better known to all entomologists was Prof. J. B. Smith, who 

 died in New Brunswick in March, 1912. His work in nearly all the 

 fields of applied entomology, and his long list of important publications, 

 caused him to rank as one of the very foremost of American entomolo- 

 gists. Within recent years his work on mosquitoes and mosquito 

 control has been of particular interest and importance. 



Among the many articles on malaria and mosquitoes one or two 

 deserve special notice. A. J. Orenstein gives an instructive article 

 entitled "Sanitary Inspection of the Canal Zone" in Amer. Jour. Pub. 

 Health, Vol. II, March, 1912, in which he describes the successful 

 fight being made there against malaria, yellow fever, plague and 

 typhoid. Much interest has been taken in the experiments first 

 successfully carried out by Drs. Bass and Johns, wherein Plasmodium 

 vivax and P. falcipar-um were grown in cultures through one or more 

 generations. 



Considerable attention has been paid to the possibilities of flies 

 carrying bacteria. Dr. J. C. Torry, in Jour. Infec. Dis. March, 1912, 

 shows that as many as 4,400,000 organisms may occur on the outer 

 surface of the fly and that 28,000,000 may be found in the intestine. 

 From 13 per cent to 37 per cent of these were found to be fecal bacteria. 

 Cox, Lissant, Lewis and Glynn report that flies in insanitary city areas 

 may contain 800,000 to 500,000,000 bacteria per fly. Tebbutt con- 

 cludes that the possibility of flies becoming infected from the presence 

 of pathogenic organisms in the breeding ground of the larvae may be 

 considered as very remote. In another series of observations Hewitt 

 finds that 700 yards was the greatest distance that houseflies flew from 

 the places where they were marked. 



The principal interest in the study of the sleeping sickness situation 

 has centered around the papers by Kinghorn and York, Stevens and 

 Fantham and others who believe that Trypanosoma rhodesiense is 

 distinct from T. gambiense and that Glossina morsitans is the carrier. 

 This of course greatly complicates the problem of controlling this 

 disease, as G. morsitans has a much wider range than G. palpalis. 



In July, 1912, the Tropical Disease Bureau ceased to publish the 

 Sleeping Sickness Bulletins and in November began the publication of 

 the Tropical Diseases Bulletin which will include reviews of literature 

 on other diseases as well as of Sleeping Sickness. 



Once more I wish to point out that the following list makes no 

 claim to completeness. It includes references (with a few exceptions)
