by a study of tlie flora after treatment with lactic cultures. Mr. Knopf 

 has ably assisted in this work, and it bids fair to be of considerable 

 moment, but has not progressed far enough to warrant a more extended 

 report. 



The study of infectious abortion is complicated by the (supposed or 

 real) presence of another venereal disease, viz., granular vaginitis. This 

 disease has been studied in Europe especially by Ostertag, who claims the 

 etiologic factor a streptococcus, embedded in the granules, and by Wil- 

 liams of Cornell, and Wills, State Veterinarian of New York. A care- 

 ful description of this affection is included in Williams' Obstetrics, 

 and need not be repeated here. We have found in a herd of Jerseys at 

 Drjden and several herds of Holsteins at Howell and Chilson as well 

 as in both college herds, a condition that answers the description of 

 this disease. In one of the herds at Howell, the lactic treatment was 

 adopted by the owner under our direction. It is too early to report 

 on the results. Infinite patience must characterize the investigation 

 of these troubles. We hope by our studies to at least be ever ready 

 to adopt any measures suggested as valuable by others more competent 

 or perhaps more favorably situated than ourselves in the conduct of 

 this very expensive work. A further discussion occurs under the ab- 

 stract on "Granular Vaginitis in Cattle." — [Ward Giltner.] 



Miscelhineons Diseases. — In addition to the ex])erimental work con- 

 ducted, Dr. Giltner has been interested in several diseases which have 

 broken out in this state, and which he has studied more or less. A re- 

 view of this work follows: 



''Infections Anemia 'n Horses at Watersmeet, Michigan. — At the re- 

 quest of Mr. Hinds, I'resident of the State Live Stock Sanitary Com- 

 mission, I visited Camp No. 15 of the Bonifas Lumber Co.. six miles 

 west of Watersmeet in the northern peninsula. I an'ived at the Camp 

 September 1st, 1910. 



There were about ten teams and a driving mra'e housed in two log 

 barns. They were in charge of Mr. Eichard Shier apparently a very 

 intelligent and ca])able superintendent. He had been in charge only 

 since spring, and had worked the teams probably rather severely, but 

 they were in good working condition. The stables were being refitted 

 with hewn log floors. 



The horses had been watered from the nearby river which had re- 

 ceived the sewage from the camp. Water had recently been supplied 

 from a 'well. On the whole, the surroundings were unobjectionable. 

 The timbered land that was the field of operation was almost exclusively 

 high land. There must have been some marsh land for swail grass was 

 being cut for the horses. 



The disease had begun in June and had resulted in eleven deaths. 

 Not half of the teams in the camp were able to do a good day's work. 

 When they returned from work at night, only one team appeared in 

 full vigor. The others looked tired, the facial expression was dull 

 and the ears drooping. 



Two veterinarians had treated the horses for influenza, and the 

 horses were not benefited. A third veterinarian. Dr. Edward Fitz- 

 simmons of Ironwood, Michigan, pronounced the disease swamp fever. 

 The nature of his treatment was not revealed to the writer.
