to a sufficiently high temperature to destroy anthrax spores within 12 minutes 

 without roasting the oats. The color of the oats was slightly darkened, but they 

 were still yellow and marketable. Chemical analyses showed thai their nutritive 

 value was not affected. 



Oxygen in milk fever, E. II. Lehnebt (Connecticut Starrs Sta. I!/>t. 1904, P- 

 l ;: I.— Oxygen was injected into the udder in one case of milk fever. The symp- 

 toms were relieved within 20 minutes and apparent recovery took place within a few- 

 hours. After H> days the normal milk flow returned. 



Treatment of parturient paresis, W. II. Ridge (Amer. Vet. Rev., 28 (1904), 

 No. .'. />/>■ l? hi '■''? I. — The author briefly out lines a considerable variety of treatments 

 adopted by different veterinarians in curing this disease. The author tested the 

 oxygen treatment in 4 cases, all of which recovered promptly and without any compli- 

 cations. During the same period 31 cases of milk fever were treated by the Schmidt 

 method, and among this number L8 recovered while II! died. Attention is called to 

 the promptness with which the effects of oxygen injections are manifested. The 

 animals rapidly regain consciousness and give no trouble to the attendants. A brief 

 description is given of a suitable oxygen tank for use in this treatment. 



The use of oxygen for milk fever, R. P. Lyman (Amer. Vet. Rev., 28 \ 1904), No.S, 

 pp. 256 .'<:.'). — The author has had nothing but excellent results in the use of this 



met hoi 1. In acute cases of milk fever where unconsiousness has already supervened, 



the author a' I ministers strychnin hypodermically in doses of \ of a grain. The in Met- 

 is then hastily inflated with oxygen. Usually the effects of the oxygen are noticea- 

 ble very rapidly, sometimes within Hi minutes, and the most serious symptoms of 

 the disease are frequently relieved in .'!•"« minutes. A plethoric condition is consid- 

 ered by the author as the most important predisposing cause of this disease. The 

 exact etiology of milk fever, however, still remains in doubt. The author uses an 

 oxygen tank under considerable pressure, and the method requires the assistance of 

 an attendant. 



Parturient apoplexy — more results from oxygen, S. S. Snydeb ( A mer. Vet. R^ v., 

 28(1004), No. 3, /i/i. 269, 270). -Detailed clinical notes are given on 9 cases of milk 

 fever treated by means of oxygen in 8 of which a complete recovery took place, while 

 1 animal died. The results of the inflation of the udder by means of oxygen were 

 manifested within a short time. 



Oxygen in the treatment of parturient paresis, J. Miller (Amer. Vet. Rev., 

 28(1904), No. 'i, pp. 868-370). A report is given on the clinical symptoms and 

 course of the disease in 5 cases of milk fevert reated by means of oxygen. A recovery 



took place in all cases within comparatively short time. The author givesabrief 

 description of the oxygen tank used in these, treatments. It is believed by the 

 author that the disease is due to the toxic products of an anaerobic organism. 



The bacterial flora of the healthy genital canal of cattle and its importance 

 in the production of puerperal fever, B. Denzler (Monatsh. Prakt. Tirrli., 16 

 ( 1904), No. 4-6, /'/'■ ! '/■'' t95). — An elaborate investigation was made for the purpose 

 of determining the species of bacteria found in various parts of the genital canal in 

 cattle. The literature relating to this subject is critically discussed in connection 

 with a sin n t bibliography. The author's investigations were made on a large num- 

 ber of cattle both before ami after death. Particular attention was given to studying 

 the extent to which the vaginal walls are capable of destroying pathogenic and 

 other bacteria. As a result of theauthor's investigations it appearsthat the bacterial 

 Bora of the vulva of cattle varies greatly, but frequently includes pathogenic micro- 

 organisms such as Staphylococcus pyogenes aureus, streptococcus, and the coli bacillus. 

 With the exception of the coli bacillus, however, these organisms show a much 

 reduced virulence. Under normal conditions no pathogenic bacteria are found in 

 the vagina and even in abnormal conditions the cervical canal, the uterus, and tin 

 oviducts are free from bacteria. The bactericidal powerof the vaginal walls in cattle
