The disinfection of stalls with dilute formalin solutions, J. S( iiniukk 

 [Ztsfhr. I iij'cktionsh-nuih-. u. II mi. Ihnislirrc. .> {lUDC). Xo. I. pp. .',.]-.',l) . — It is 

 often liossihle to ^et a lieiter penetration with Hnid than with j^aseous formalin, 

 especially in stables in wliich there are cracks in the floor and other parts. 

 The author tlierefore tested tiie value of formalin in an aijueous 1 ])er cent

Trypanosomes, F. (J. Now {.lour. Aiiicr. MnJ. .t.s\oc.. .J,S (7.907), Xos. J. pp. 

 I -III; J. pp. 12.'i-121, /?.(/*•• 10). — The structure and biology of trypanosomes, 

 jiathogenic for animals, are described in detail, and notes are given on the 

 transuHssion of trypanosomes and on the immunity produced in animals against 

 protozoan diseases. Specific accounts are presented on the nature, etiology, and 

 UH'thod of treatment of uagana, dourine, Gambian horse disease, galziekte, 

 sleeping sickness, and related diseases. 



The cattle tick, W. Newell and M. >S. Dougherty (Crop I'r.'^t Com. Ln. Circ. 

 III. pp. 32, p!i><. S). — The authors present a general discussion of the imiiortance 

 of tide eradication to the improvement of animal industry in the southern 

 States. 



The life history of the cattle tick is described with particular reference to 

 its agency in transnutting Texas fever and to the adoption of rational schemes 

 for its eradication. Tables are presented showing the periods during which 

 cattle and other animals must be kept off of pasture lands at different seasons 

 of the year in order to free these lands from ticks and make it safe to readmit 

 tick-free cattle upon them. On the basis of this practical Information it is a 

 relatively simple matter for stock men to free farm lands of ticks. 



Stomach worms (Haemonchus contortus) in sheep, B. H. Ransom ( f7. 8. 

 I><pf. A(ir.. liiir. Aiiim. Iinliis. Circ. 102. pp. 7). — The symptoms of infestation 

 by this worm are lirietly noted. In ]ireventing the infestation of lambs with 

 stomach worms two general plans are usually apidicable. The ewes may be 

 kept in a bare lot from which the lambs may escape to noninfested pasture for 

 grazing. The danger of infestation is thus reduced to a minimum. Again, 

 wherever it is practicable, the danger of infestation from stomach w^orms is 

 largely eliminated if the lambs come in the fall rather than in the spring. 



P.rief notes are given on the direct remedies for stomach worms, including 

 coal-tar creosote, bluestone, and gasoline. 



Department of animal industry, X. S. Mayo (In forme An. EMtac. Cent. 

 Afiron, Cuba. 1 {190.'f-5), pp. Jfl-'io). — A brief statement is made regarding the 

 efforts put forth to improve the grade of domestic animals in Cuba, together 

 with notes on some of the more important animal parasites of tjie live stock. 



The urology of rabies, C. Poiu her (.lour. Mrd. Vet. ct Zootech., .57 (1906), 

 pp. ~tU)~l.i2). — A chemical and physical study of the urine in cases of rabies 

 among dogs, rabiiits. goats, and donkeys, disclosed the presence of sugar in 

 nearly all cases which died of the disease or which were killed during its pro- 

 gress. On the other hand, the urine of healthy animals of the same species 

 contained sugar in only 2 cases as contrasted with 29 cases in which no sugar 

 was found, '{"be ^-ugar does not appear in advance of the development of the
