182 EXPERIMENT STATION RECORD. 



within 24 hours after mixins. When administered hypodermically, it causes 

 no bad effects at the point of inoculation. The author reports that he has used 

 this remedy on more than 40 experimental animals, Including horses, cattle, and 

 sheep, in some cases administering as nuich as 500 cc. Considerable benefit is 

 alwajs manifested from the use of hemoglobin in cases where the amount 

 is below normal. 



Recurrence of parturient paresis, Kahn (Brrliii. Tierdrstl. WcJinschr., 

 1906, A'o. 11. p. 322). — In the experience of the author as well as that of other 

 investigators, the recurrence of parturient paresis soon after an apparent 

 recovery Is very rare. Notes are given on a case In which air Infiltration was 

 used in the treatment of the disease. The cow recovered within a few hours, 

 but suffered a relapse 5 days afterwards. Air Infiltration into the udder was 

 again administered, after which recovery took place without a recurrence of the 

 disease. 



Parturient paresis, Gebaueb (Berlin. Tieriirztl. WclDtscUr.. 1906, Xo. 20, pp. 

 377-310). — In a lirief review of the literature of this subject the author gives 

 particular attention to the investigations of Iless and Zehl. The evidence thus 

 far preser'ted for considei'ing parturient paresis as an infectious disease is not 

 very strong. The most characteristic and pronounced symptom is cerebral 

 anemia. The author believes that the often-observed cessation of the milk 

 secretion in cases of this disease is an attempt on the part of the organism to 

 compensate for the disturbed circulation. In one Instance the author observed 

 a case In which the symptoms were identical with those of parturient paresis 

 and the Infusion of air into the udder caused a prompt improvement, but later 

 serious symptoms occurred and the animal was slaughtered. It was found in 

 this case that the cerel)ral anemia was due entirely to a vaginal hemorrhage 

 which had lowered the blood pressure. 



Milk fever before parturition, Gallier (Bid. Hoc. Cent. Med. Vet., S3 {1906), 

 \(i. I), p. l')3). — This disease, while always related to parturition, sometimes 

 occurs before as well as after this event. Notes are given on a case which 

 came under the author's oliservations. A comiilete recovery took place after 

 the api)lication of the Schmidt treatment. 



The treatment of infectious vaginal catarrh of cattle, II. Raebiger (Berlin. 

 Tierdrztl. Wchnsehr.. 1906. l^o. 13. pp. 2',1. 2J,2, figs. 4).— In the treatment of this 

 disease considerable difficulty has been experienced on account of the merely 

 temporary effect of ordinary antiseptic washes. 



The author devised a syringe, by means of which dry antiseptic materials 

 and also salves could be injected. The results obtained from the use of this 

 apparatus have been very satisfactory. It is considered, however, that in all 

 cases in which the uterus is also affected the cow should be fattened and sold 

 for beef since, if she is kept in the herd, it is practically iin]iossible to prevent 

 the further spread of the disease. 



The enzootic appearance of gangrenous vaginitis in cows, A. M. Bekgmann 

 (Furtschr. Vet. IlutJ-, 'i (19il6), Xo. 1, pp. 1-6). — The disease occurs most fre- 

 quently in connection with calving and attacks chiefly heifers and young cows. 

 A brief account is given of the persistence of the disease from year to year in 

 a badly infected herd. The cause of the disease is infection with the necrosis 

 bacillus. In order to prevent infection of the milk of diseased cows. It ap- 

 pears to be necessary to make frequent use of lysol douches. This treatment 

 should be applied immediately after parturition. 



Notes on the enzootic occurrence of gangrenous vaginitis in cows, A. M. 

 Bergmann (Hvensk, Vet. Tidskr:. 11 (1906), No. 3. pp. 117-120). — Several cases 

 of this disease have come under the observation of the author. The usual 

 symptoms and pathological alterations are described. Quite satisfactory re-
