begun early in 1916 and carried through, the 

 summer of 1917, but, owing to Professor 

 Herms's absence while serving with the United 

 States Army, the -work was held in abeyance 

 until the opening of this year. The greater 

 part of the summer's work was carried on in 

 the San Joaquin Valley, however, several 

 weeks were spent in the mountainous coun- 

 tries of Alpine, Mono and Inyo and in portions 

 of San Bernardino. The highest elevation 

 reached was approximately ten thousand feet 

 and the highest elevation at which Anopheline 

 mosquitoes (Anopheles quadrimaculatus) were 

 encountered at any time during the survey 

 was 5,482 feet. A total of 18,088 miles were 

 covered in the survey, all by automobile. A 

 report of the survey in the northern third of 

 the state has already been published (U. S. 

 Public Health Eeport, July 18, 1919) and 

 other reports will be issued in due time. The 

 survey was conducted under the joint aus- 

 pices of the California State Board of Health 

 and the University of California.

DIRECT PHOTOGRAPHY OF COLONIES OF 

 BACTERIA 



In view of the desirability at times of 

 obtaining photographic record of i'etri dishes 

 which have been inoculated with bacteria and 

 incubated, the following extremely simple and 

 rapid method may prove useful. 



The special value of this method from the 

 pedagogical point of view is its simplicity, no 

 camera, plates, or dark room being necessary. 

 This makes it possible for all members of a 

 class to preserve accurate and permanent 

 records in comparing bacterial counts in 

 samples of water or milk, to show form of 

 growth on Petri dishes, to illustrate the
