88 EXPERIMENT STATIOX KECOKD. 



The toxin of glanders bacillus, It. Turko ((Joniiil. Rend. Hoc. Biol. [Paries], 

 G.'i (JDOfi), ^o. 3, pp. 130, 131). — The author deseri))es the technique for obtain- 

 ing a new form of niallein or toxin from tlie .slanders bacillus which acts as an 

 aggressiu. 



Abscess formation in the hypoglossal glands of horses affected with 

 glanders, E. Lienaux {Ann. Mrd. Vet., 56 {lUOl), Xo. 12, pp. G'/3-G'iS). — It is 

 couunonly stated that the glanderous process in the lyuipliatic glands of the 

 horse does not lead to formation of abscess. As a rule at least, this statement 

 is true. The author reports, however, one case in which the hypoglossal glands 

 were extensively affected with abscess. 



Combating glanders in Dutch East Indies, W. Tax dkr Bubg (Tijilschr. 

 ^'(^c(lrts(■llijk., 3.3 {J!)07), Xo. 3, pp. L'/O-lol). — From a report of the occurrence 

 of glanders in the Dutch East Indies and the methods of control adopted in 

 Java, tlie author maintains that the system is altogether too lax and that unless 

 niallein is more extensively used as a diagnostic agent and the necessary quar- 

 antine measures carried out, it will be impossible to control the disease. 



A study of the toxin in ulcerous lymphangitis of the horse, Dassonville 

 (Bid. Hoc. Cent. Med. Vet., S.'f {IDOl), Xo. 2.'i, pp. o76~oS2).— The author de 

 scribes the methods used in isolating and studying the toxin of ulcerous lymphan- 

 gitis. It is found that the bacillus of this disease produces a very active toxin, to 

 which guinea pigs and rabbits are very susceptible, dogs and cats less suscepti- 

 ble, and white mice almost if not quite refractory. The action of the toxin is 

 readily modified by heat or by the use of various acids. 



The symptoms and lesions produced by the toxin closely resemble those which 

 occur as a result of diphtheria toxin, and the properties of the toxin as a whole 

 Indicate that it is very similar. The similarity is particularly evident from the 

 fact that diphtlieria antitoxin greatly modifies or counteracts the toxin of ulcer- 

 ous lymphangitis. 



The treatment of mange in dogs, Dietz (Berlin. Tierdrstl. Wchnsclir., 1901, 

 Xo. .'/S, p. 867). — In treating mange due to Acarus mites the author has found it 

 desirable to shear the hair as closely as possible from infected dogs after which 

 a mixture of tincture of iodin and cream is thoroughly rubbed on the affected 

 parts. 



Piroplasma canis and its life cycle in the tick, S. It. Christophers (Hci. 

 Mem. Med. and Sanit. Depts. India, n. ser., 1907, Xo. 29, pp. 83, pis. 3, figs. .'/. 

 charts 7). — The literature relating to this protozoan parasite and related 

 organisms is criticallj' discussed in connection with an elaborate bibliography 

 (pp. 67-77). In the tick Rhipiccphalus sanguineus there are at least two 

 means by which transmission may be effected. One is through the egg and the 

 other a stage to stage infection. The latter has not been demonstrated experi- 

 mentally, but must be assumed to be true from observations which have been 

 made. The parasite passes through the same cycle of development in both 

 methods of infection. In hereditary infection club-shaped forms originating 

 from simple parasites penetrate the ova either in the ovary or in the lower 

 passage of tlie oviduct. 



[A bacterial growth on chickens], D. W. May (Porto Rico Hta. Rpt. 1907, 

 p. 15). — A disease, seemingly a bacterial growth, has been noticed which pro- 

 duces lumps on the comb and at the base of the bill. Washing the heads of the 

 fowls with a saturateil solution of boric acid gave relief. 



The persistence of contagion of fowl cholera, P. V. Sizov (ArcJi. Yet. Xauk 

 [St. Petersb.], 37 (1907). Xo. 10. pp. S'i7-850).— It is commonly stated that 

 after the occurrence of this disease an infected condition of the premises may 

 persist for 3 or 4 mouths. In the author's experiments it was found that the
