organism to various physical and chemical disinfectants is not very striking. Ordi- 

 nary chemical substances in tlie usual proportions and heat above 60° C. are suffi- 

 cient to destroy the organism. The author presents a detailed comparison between 

 the characteristics of the organism of fowl plague and those of pneumonia of cattle, 

 South American horse disease, foot-and-mouth disease, diarrhea of young calves, etc. 

 The dog and fox proved in experiments to be refractory to the disease. Inoculation 

 experiments with rabbits were made with doubtful results. Pigeons appear not to 

 be subject to natural infection and the virus was eaten by these birds without 

 l)ecoming infected. In a number of cases hypodermic injection of the virus of the 

 disease in pigeons failed to produce any pathological symptoms. In a few young 

 pigeons, however, a peculiar set of symptoms was produced, of which the most 

 characteristic was the loss of etiuilil)rating power and a tendency to fly or walk in 

 circles, with evidences of dizziness. 



Combating fowl cholera, Buhl {Berlin. Thierarztl. Wchnschr., 1903, Xu. 13, jjp. 

 193-197). — This article contains a general account of the nature and symptoms of 

 fowl cholera, with special reference to the various means by which it may be dis- 

 seminated. Attention is called to the statutory laws on this subject, according to 

 which punishment is provided for carelessly or intentionally having any traffic in 

 or moving about from jjlace to place fowls which are affected with this disease. A 

 bibliography of the subject is appended to the article. 



Psittacosis, G. A.jello and C. Parascandolo {Arch. Parasit.,5 {1902), No. 5', pp. 

 294-39.')) . — The authors present an elaborate discussion of the symptoms and etiology 

 of this disease, together with the appearance and behavior of the pathogenic organism 

 and of the toxin obtained from pure cultures. The literature of the subject is dis- 

 cussed in connection with an extensive bibliography. The authors conclude from 

 their experiments that the bacillus of psittacosis is specifically distinct and possesses 

 specific morphological, physiological and biochemic properties. Filtered cultures 

 are toxic for the ordinary experimental animals and the bacilli jiroduce relatively 

 slight lesions in rabbits and guinea pigs. By means of bacterial cultures it is 

 possible to immunize rabbits and dogs, and the serum of these animals is endowed 

 with a preventive and curative jiower against the disease. 



The bacterial flora of the feces of fowls, tog-ether with notes on a new fowl 

 plague, E. JoEST {Berlin. Thieriirztl. Wchmchr., 190.2, Xo. 16, pp. 241-~43) . — Notes 

 are given on numerous bacterial organisms which were found in the various parts 

 of the alimentary tract and in the feces of fowls. An organism was isolated from a 

 fowl suffering with a new form of infectious disease, and this organism is believed 

 to be specifically different from all known bacteria. Notes are given on the staining 

 affinities and the behavior of the organism in various nutrient media. The name 

 adopted by the author for this organism is Bacterium infe^ftinale gaUinarum. The 

 organism is non-motile and -apparently does not form spores. 



The significance of the recent American cases of hookw^orm disease (unci- 

 nariasis or anchylostomaisis) in man, C. W. Stiles (f. >S. iJept. Agr., Bureau 

 of Animal Industry Rpt. 1901, jyp. 183-219, figs. 84)- — Notes are given on the occur- 

 rence of hookworm disease in this country, due to infestation by Uncinaria duodenalis. 

 A detailed description is presented of this species, together with a brief account of 

 related species which have been found in other domestic animals in this and other 

 countries. The life history of the hookworm is given, together with an account of 

 the source of infection, symptoms of the disease in man, its clinical diagnosis, treat- 

 ment, and prevention. Alsstracts are given of the various cases which have been 

 rejiorted in the United States and a bililiography of the subject is appended to the 

 article. 



The burning of dead animals, R. H. jNIcDowell {Xerada *SV«. Bui. 53, pp. 12). — 

 Brief notes are given on the use of unslaked lime, which may be sprinkled upon 

 diseased fowls in connection with l»urviug them in the ground. Attention is called
