1128 EXPERIMENT STATION RECORD. 



/>'. proteus. In the case (if />. pyocyaneus, however, the influence of the food was 

 very marked. In thepigeona fed on milk the average amount of agglutinins pro- 

 duced was about 7 times as much as in those fed on potatoes. 



Experiments were also undertaken to determine the effect of alcohol upon rabbits 

 inoculated with typhoid bacilli. In these tests it was found that the control animals 

 produced about4 times as much agglutinin as the rabbits which received alcohol. 

 The author also tested the effect of sodium cinnamate or hetol upon rabbits after 

 inoculation with typhoid bacilli. The increase in the production of alexins after 

 treatment with hetol was very pronounced, and this fact is considered of some 

 importance in the treatment of infectious diseases of animals and man. 



The agglutination of red blood corpuscles by chemical precipitates and 

 the suspension of these precipitates in colloidal media, 0. Gengou (.1////. Inst. 

 Pasteur, 18 (1904), No. 11, pp. 678-700). — The literature relating to this subject is 

 briefly discussed. During the extensive series of experiments carried out by the 

 author it was found that certain chemical precipitates agglutinated and later destroyed 

 the washed red blood corpuscles. This agglutination is due to the direct action of 

 the precipitates upon the corpuscles. The blood serum, even in small doses, hinders 

 agglutination and hemolysis. 



Natural and conferred resistance to disease in the animal body, F. C. Lewis 

 ( Vet. Jour., 59 ( 1004), No. 354, PP- 815-328), — A general discussion is presented on the 

 subject of immunity, together with a special account on active immunity, passive 

 immunity, antibacterial serum, and Griinbaum's serum reaction. 



Friedberger and Frohner's veterinary pathology, trans, by M. H. Hayes 

 (London: Hurst and Blackett, Ltd., 1904, vol. 1, XII +519).— This is a translation 

 from the fourth German edition with numerous additions by the translator on surra, 

 South African horse sickness, Texas fever, louping ill, etc. The volume contains a 

 special discussion of the most important infectious diseases of animals as well as of 

 chronic constitutional diseases, and notes on bacteriology. 



Pathological observations, G. Petit (Bee. Med. Vet., 81 (1904), No. 21, pp. 

 6 7 3-682, figs. 2). — Notes are presented on a variety of pathological processes includ- 

 ing icterus, pneumonia in dogs, and lymphangitis and anasarca in horses. 



Annual reports of proceedings under the diseases of animals acts, A. (J. Cope 

 and A. W. Anstruther (London: did. Ayr. and Fisheries, 1904, PP- 94, ph. 2). — A 

 general account is presented of the effective work which has already been done in 

 eradicating and preventing further introduction of such diseases as cattle plague, 

 pleuro-pneumonia, foot-and-mouth disease, rabies, etc. No case of rabies has been 

 noted in Great Britain since 1902. 



Glanders among horses is on the increase and the same statement is made for 

 anthrax. The great distribution of anthrax is believed to be due in part to infection 

 through food and drinking water. No outbreak of foot-and-mouth disease occurred 

 among native animals in Great Britain during 1903. A detailed account is given of 

 the present status of hog cholera and sheep scab and the relative changes in the dis- 

 tribution of these diseases are indicated on special maps. 



The veterinary section, A. Theiler {Transvaal Agr. Jour., 3 (1904), No. 9, j>p. 

 49-98, pi. i).— A report is made on investigations relating to African coast fever. 



A test was made to determine the length of time during which an infection per- 

 sists in a given area. With regard to this point the South African conference of 

 veterinary surgeons adopted a resolution to the effect that the only certain method 

 of eradicating African coast fever is to kill off all cattle in infected areas and to keep 

 cattle away from such areas for a period of not less than 18 months. The methods 

 of vaccination proposed by Koch were tested on a large scale and it was found that 

 little hope can be entertained of permanent good results from these methods. 



Dipping and spraying experiments were also tried, during which arsenical dips 

 were used with or without other additions. Arsenical dips repeated at frequent
