animals and upon the symptoms and course of the disease. The pathogenic organism 

 is described and figured. 



A diag-nosis of rabies, II. Valee {Rev. Vet. Toulouse, 35 {1900), Xo. 12, pp. 

 76S-768) . — A brief critical discussion of the various methods "which have been pro- 

 posed for diagnosing rabies before and after death. 



Diagnosis of rabies upon an histological examination of nerve centers of 

 animals which have died prematurely, C. Frax(;a ( Compt. Rend. Soc. Biol. Paris, 

 53 {1900), No. 36, pp. 985-987). — From microscopic iiost-mortem examinations made 

 by the author it is concluded that rabid animals which die prematurely do not 

 always exhibit the rabic nodules in the ganglia. More frequently it was found that 

 such elements exist only in an extra capsular position in a greater or less quantity. 

 Lesions in the bulb were more striking and were formed earlier than those in the 

 ganglia. 



Rabies in dogs, I. Guerricabeitia {Gac. Med. Vet., 24 {1900), No. 174, PP- 

 513-516). — Brief notes by way of diagnoisis of this disease. 



Common diseases of the fowls — their control and treatment, F. D. Chester 

 {Delaware Sta. Bui. 47, pp. 30, figs. 12). — This bulletin contains a general account of 

 the common diseases of poultry. The author discusses the symptoms, etiology, and 

 treatment of gapes, simple catarrh, roup, pip, noninfectious gastroenteritis^ fowl 

 cholera, asthenia, blackhead, various diseases of the reproductive organs, vertigo, 

 epilepsy, scaly leg, depluming scabies, favus, bumblefoot, tuberculosis, and infectious 

 leukaemia. 



Roup of chickens, E. V. Wilcox {Montana Sta. Bui. 22, pp. 27-29). — A brief 

 description of the disease and an account of the remedies usually adopted against 

 this disease are given. During an outbreak of roup in Montana diphtheritic mem- 

 branes were removed from the mouth and larynx and a direct application of lunar 

 caustic was then made to the raw surface thus exposed. The mouth cavity and eyes 

 were then washed with a solution of nitrate of silver in the proportion of 8 grains 

 to the ounce of water. In some cases 1 application was successful, while in others 

 2 or 3 were required. 



The internal chicken mite, E. V. Wilcox {Montana Sta. Bui. 22, 2'>p. 30-36) . — A 

 brief description of Cijtodites nudus is given and the literature relating to this species 

 is discussed. While studying this mite in Montana it was found in 5 chickens 

 which were evidently suffering from some serious disease. In 1 case a large number 

 of intestinal nematodes were present and in the other 4 cases the chickens were 

 affected with nodular t;eniasis. Two perfectly healthy chickens were found to be 

 thoroughly infested with cytodites, and in these cases, as well as in the others, no 

 lesions were traceable to the action of cytodites. Thorough disinfection of poultry 

 houses is recommended as a preventive measure against this mite. 



Intestinal helminthiasis of fowls, Railliet {Rec. Med. Vet. Paris, 8. ser., 7 {1900) , 

 No. 2, pp. 36-43). — The author studied an outbreak of helminthiasis among fowls 

 which was caused by Heterakis j)erspiciUum, H. visicularis, Darainea cesticillns, and D. 

 proglottina. A serious mortality resulted from the presence of these parasitic worms. 

 The remedies which were tried included calomel, areca nut, santonin, ether extract 

 of male fern, and a mixture of the last two. 



Calomel in doses of 2 to 4 eg. gave no result. Areca nut in doses varying from 2 to 

 6 gm. was ineffective. Santonin, even in doses of 28 mg., produced no appreciable 

 effect. One pullet in a period of 3 weeks received 70 mg. of santonin and 50 eg. of 

 the ether extract of male fern without any appreciable effect on the intestinal 

 parasites. 



Forceps for holding pigs during inoculation, Bury {Berlin. Tierdrztl. 

 Wchnschr., 1900, No. 33, p. 388). — A brief description of a form of forceps which 

 proved to be convenient for this purpose.
