The section of the Hall of Public Health dealing with insect- 

 borne diseases has been brought to a state of practical com- 

 pletion after nearly four years of work. To the 

 mosquito exhibit have been added models showing 

 various practical methods of mosquito control (such as ditching, 

 oiling of streams, protection of receptacles in the neighborhood

 models, charts and an oil painting illustrating the story of the 

 triumph of American sanitation on the Isthmus of Panama.

 stalled, containing a rather complete exhibit dealing with sleep- 

 ing sickness and relapsing fever and with the tsetse flies and 

 ticks which carry the germs of these diseases. These include 

 specimens of the flies and ticks, photographs and charts illus- 

 trating the diseases and their prevalence, and models which 

 show how the flies and ticks are controlled in Africa by clear- 

 ing the jungle and burning infested villages.

 now on exhibition in the Hall of Public Health, and who at 

 the time of his death was engaged on a model of the yellow 

 fever mosquito, Aedes calopus. We have been fortunate, how-
