[A new treatment of virulent forms of mastitis], J. Schmidt (Maanedskr. 

 Dyrlager 21 {IDOiJ), \o. 18, pp. J,92, 4i)3; ab.s. in \ Ct. lire. .12 {1910), No. 112J,, 

 pp. 1/89, J/OO). — A new treatment for severe forms of inflammation of the udder, 

 successfnlly nsed by the author, is that of infusing a mixture of equal parts 

 of alcohol and glycerin into the affected quarter. 



As a rule 250 gm. (approximately 8 oz.) is injected at once. If it appears 

 possible that the affected quarter may again become functional for milk produc- 

 tion, the author dilutes the above mixture with one-third of normal saline solu- 

 tion, in order not to irritate the mammary epithelium too much. The affected 

 quarter is not milked out during the 3 days following the infusion. If two or 

 more quarters are affected, the treatment is practiced upon only one quarter. 

 The author finds that this treatment is at-companied by a substantial improve- 

 ment in the animal 3 or 4 days after its application. It is stated that usually 

 the animal's life is preserved, though it is not always possible to restore milk 

 production to the affected quarter. 



Cattle in the West Indies, D. W. May {Porto Rico Hort. News, 3 {1910), 

 No. .'/, pp. 59. 60). — The fact that cattle ticks are not so plentiful in Porto Rico 

 as in the Southern States tjie author considers due in large part to a blackbird 

 v.hich follows the cattle about, picking off" the ticks. This bird has been observed 

 grasping the tail with both feet and feeding ui)on the ticks infesting the hind 

 quarters of the animal; it is said that it will also stand on the ground beneath 

 the animal and jump up to pick off the ticks. While the ticks will attach to 

 the zebu cattle, they are seldom found in numbers on animals with zebu blood. 



"Doubtless tick fever exists in Porto Rico, but of the 50 head of cattle 

 ))rought from the States and which were at the station, only 3 had been 

 inoculated. No losses occurred from tick fever although the cattle were infested 

 from the start with ticks. Either the disease is in a much milder form than 

 in the Southern States ov else there is some virtue in the Malojillo grass which 

 forms the main feed." 



Serum treatment of infectious calf pneumonia {Vcroffcntl. Jahres-Vet. Ber. 

 Ticriirzfc Prciif^s., 8 (1907 [pub. 1909]), pt. 2, pp. 1',. 15; ahs. in Berlin. 

 Tierurzth Wchnsclir., 26 {1910), No. 7, p. 151/). — The serum treatment furnishes 

 good results only when it is begun early, the best time being directly after birth. 



Anthrax in the pig, Eggebrecht {Ztschr. Fleisch u. MUchhyg., 20 {1910), 

 No. ,}. pp. 121 ; nhx. in Ann. Med. Vet.. 59 {1910). No. 3, p. 18'i; Vet. Rec., 22 

 <1910), No. 1133, p. 632). — A case which was brought to the abattoir with 

 symptoms of exhaustion and great weakness is reported. The only abnormalities 

 found were pleurisy, sero-fibrinous peritonitis, and the condition of the blood, 

 which was black and not coagulated. Tokishige of Tokio reports cases of 

 porcine anthrax to occur in Japan that are only manifested by such sj'mptoms 

 as weakness, loss of ai)petite. etc. 



Experiments with variola of swine, J. Poenaru (Bal. Soc. Cent. Med. Vet.. 

 87 {1910), No. 6, pp. l.'i'i-Uil, flg. I). — Swine pox was found to be transmitted 

 at times with the blood from cadavers and from diseased pigs to healthy ones, 

 also through the inoculation by scarification of material from pustules. Dodd's 

 spirochetes did not appear in the blood nor in new vesicles, but were later found 

 i)i ulcers as accessory organisms.
