FOREWORD. 



Technical Bulletin No. 32. 



The bovine infections abortion problem has been studied in our labora- 

 tory under the direction of Mr. Cooledge who has charge of the project, 

 ''The Effect of Diseases in the Cow on the Milk." Mr. Huddleson, assist- 

 ing in carrying out the details of the general plan, has undertaken to 

 determine the extent of injury inflicted upon the calf as a result of the 

 ingestion of milk known to be infected, naturally or otherwise, with 

 Bacterium ahortns. This is a matter of the gravest importance to the 

 whole cattle industry. The results recorded in this paper, made possible 

 by methods of study evolved in this laboratory, contradict certain im- 

 pressions that are gaining ground amongst those in a position to offer 

 treatment for the disease in question. Fortunately Mr. Huddleson is in 

 a position to pursue his studies in this connection with increased vigor.
