in windy weather. This was due to a hydrolysis of the glycogen present in 

 the muscles, particularly the muscles of the buttocks, causing a myositis — pri- 

 marily due to the abstraction of water from the muscle — and a secondary acute 

 nephritis. The author observed that when hemoglobinemia was diagnosed at 

 the outset of the disease there was also a discharge of dextrose with the urine. 



Twist or displacement of the pelvic flexure of the colon in the horse; 

 differential diagnosis between that condition and simple impaction of the 

 same portion of the bowel, together with remarks on the spontaneous reduc- 

 tion of twist and the comparative rarity of enteritis, II. C. IIeeks {Jour. 

 Compnr. Path, and Tlicr., 21t (1911), No. 4, pp. 306-328, figs. S).— The main object 

 of the notes here presented is to point out that " in the great majority of our 

 fatal cases of colic it is this displacement of some portion of the double colon 

 that occasions the animal's end." 



Treatment of pleuro-pneumonia of horses by autoserotheraphy, L. Teppaz 

 (Bui. Soc. ScL Vet. Lyon, HJJO, Jutij, p. :i2D ; aJj.s. in Jicrllii. Ticnirzlt. Wctinschr., 

 21 (1911), No. 35, pp. 626, 627). — A 7-year-old horse was treated successfully 

 with subcutaneous injections of its own pleural exudate, 15 cc. being given under 

 the skin of the neck. The pleural fluid when sown on gelatin was found to 

 contain the Staplnjlococcus albiis, which was not very toxic for dogs. 



Note on certain protozoan organisms observed in the rectal and cecal 

 contents of the turkey and fowl, W. Jowett (Jour. Compar. Path, and Thcr., 

 2'i (1911), No. .'1, pp. 303-305, fig. 1). — A brief account is given of certain flagel- 

 lated and spirally-formed organisms encountered in the course of examination 

 of the fluid and semifluid rectal and cecal contents of the turkeys which formed 

 the subjects of study of the blackhead disease (E. S. II., 2G, p. 588). 



Researches on the spirochetosis of fowls from Tunis and on Argas persi- 

 cus, which transmits the disease, B. Galli-Valerio (Gentbl. Bakt. [etc.}, 

 l.AU., Orig., 61 (1911), No. 6, pp. 529-537, figs. 4).— In investigations conducted 

 at Lausanne, the author has found the fowl tick (A. persicus) from Kairouan 

 to transmit the chronic form and those from Houmt-Souk (island of Djerba) 

 to transmit the acute form of spirochetosis. The author considers this disease 

 of poultry to be caused by a single spirochete (Hplrochwta anserina of 

 Sacharoff). 



In studies of the biology of the fowl tick, the author found that this parasite 

 had a marked predilection for the blood of birds but that it may at times even 

 attach to cold-blooded animals if their skin be warmed. 



Warty typhilitis of the pheasant and the parasite which causes it (Hete- 

 rakis isolonche), A. Lucet and A. Henry (Bui. Soc. Cent. Med. Vet., 88 (1911), 

 No. I'l, pp. 320-333, figs. 15). — Fathological and systematic studies are reported 

 and a bibliography of 7 titles is appended. 



RURAL ENGINEERING. 



The present stage of irrigation development and a forecast of the future, 

 S. FoRTiEK (Inig. Age, 27 (1912), No. J,, pp. 128-130) .—This article briefly 

 reviews the development of arid regions during the past 20 years by irriga- 

 tion, discussing government aid to irrigation, the importance of irrigation to the 

 Western States, money invested in irrigation works, agencies in irrigation 

 development, the geographic distribution of irrigation enterprises, and improve- 

 ment in irrigation practice. In order to safeguard all interests, the author 

 advocates the speedy settlement of lands now irrigated, the aiding of settlers 

 on irrigated farms, a readjustment of laud values, the more economical use 

 of appropriated water supplies, better state irrigation laws, and more efficient 

 administrative systems.
