centre. After a fortnight one container is full and the other is then 

 utiUsed. About 10 days after beginning to fill the second container 

 the first is emptied. The liquid that collects at the bottom of the 

 containers is led away through a pipe to a sealed pit. Owing to the 

 great heat developed within the containers the eggs and larvae of 

 flies are not found except sometimes on the inner surface of the metal 

 covers of the doors.

The study of mosquitos by the U.S. Army medical authorities 

 was carried on as far back as 1901. In 1918 collections of mosquitos 

 were received from 57 stations with the following results. 



Anopheles punctipennis, A. quadrimaculatus and A. walker i were 

 recorded from Michigan ; A. punctipennis from Washington ; A. quadri- 

 'maculatiis, A. barber i and A. atropos from the Atlantic coast States. 

 A. jjseudojyunctipennis is confined to a comparatively small region 

 in the south-west, apparently not east of Texas nor north of San 

 Francisco, but it extends southwards and is taken in large numbers 

 in Panama. A. crucians occurs from the general vicinity of Washington, 

 D.C., down the Atlantic coast States, in the Gulf States as far as 

 Louisiana and up the Mississippi as far as Arkansas. The localities 

 suggest some peculiar choice of breeding-places, not yet sufficiently 

 worked out, though Dr. Metz has given very interesting points 

 \R.A.E., B, vii, 47, 88]. 



Specimens of Stegonujia fasciata were received from Chattanooga, 

 Austin, San Antonio, Montgomery, Carlstrom Field, Florida, and 

 Camp J. E. Johnston, Florida. 



The routine methods at the Army Medical Museum are the examina- 

 tion and determination of specimens and the recording of each lot 

 under its proper post. The records cover all points available, and 

 a report of the findings of the collection is then sent to the camp 

 surgeon and a memorandum prepared showing the posts, dates, 

 and in what number disease-bearing mosquitos were taken.

This is the first record of recurrent fever in Peru. The disease 

 occurred in the department of Huancavehca, where poverty, lack of 

 hygiene, scarcity of food, and abundance of lice, were the prevalent 

 conditions.
