teriology and histo-pathology of several calves from infected henls. At 

 this time we do not care to publish a' detailed report of the-<e cases but 

 may say that only in one case studied have we obtained evidence of the 

 presence of livinp; micro-organisms in the reproductive organs. In no 

 case have we found any evidence that an inflamimaitory condition of the 

 reproduictive organs due to baicterial infection exist. The one case ex- 

 cepted above is a Holstein calf prematurely delivered July 0th, 1921, 

 was due August 23, 1!)21. Tlie calf was thrifty during tlie lirst six weeks 

 of life and then began to dec;ine. It was killed October 12th, 11)21. In 

 the liver of this calf were sixteen to eighteen shaiply circumscribed 

 abscesses varying from ten to fifty millimeters in diameter containing a 

 thick creamy pus. Bact. lipolyticus type C was isolated from these ab- 

 scesses. The same organism was isolated from the uterus. There was no 

 evidence of any reaction (inflammation) in the uterus resulting from 

 this organism. This probleni will be continued during the ensuing year 

 and we hope to have sufficient material in the not distant future to war- 

 rant publication of the results. 



Mr. Huddleson of tlie Department of Bacteriolog-y has kindly made all 

 bacteriological examinations in the cases referred to above.

REPORT OF THE SECTION OF BACTERIOLOGY 



Director R. S. Shaw, 

 College. 



Dear Sir: The past year has seen no changes in either personnel or projects 

 in this Division. For the first time since our entry into the Great War we 

 are able to report uninterrupted progress in all lines with a complete staff of 

 well qualified men. It is needless to say that our achiev3m3nts even in the 

 very limited fields explored have themselves been limited, seriously and 

 uneconomically so, by lack of substantial appropriations for men and mate- 

 rials. We should have numerous assistants working under the direction of 

 the mature well trained experts in the various fields of bacteriology. A 

 plan involving the use of numerous younger men and women should be very 

 helpful to us, economical to the State, and satisfactory to the aspiring 3''oung 

 assistant. Of course they would come and go, but that need cause no em- 

 barrassment to either party concerned. Both the human element and the 

 work itself would be properly considered. 



Mr. Tweed's time has been distributed amongst teaching, studies of various 

 phases of fermentation and research on ''The effect of diseases of the cow 

 upon the piilk." (Adams la.)
