the production of specific hemolytic and agglutinating substances when injected into 

 animals of another species. Blood corpuscles fixed by formaldehyde cause the pro- 

 duction of agglutinins and hemolysins and are in turn susceptible to agglutination 

 by specific sera. 



Normal agglutinins, R. Schellek ( Centbl. Bakt. u. Par., 1. Abt., Orig., 36 ( 1904), 

 No. 3, pp. 4&7-441 I- — On the basis of his experiments the author concludes thai nor- 

 mal horse serum agglutinates typhoid bacilli in dilutions of 1:100. Dead typhoid 

 bacilli are similarly agglutinated at temperatures of 60 to 62° C. Distinction is made 

 by the author between agglutinins and agglutinoids in normal immune sera. 



Epizootic lymphangitis, Gkay (Rhodesian Agr. Jour., 1 {1904), No. 4, PP- 7S- 

 80). — The symptoms and etiology of this disease are briefly described. It is said to 

 be amenable to treatment if taken in time. Carbolic acid and other antiseptics arg 

 recommended. 



The varieties of Bacillus cedematis maligni, Kiesten {Arch. Wiss. u. I'rakt. 

 Tierh.,30 {1904) No. 3, pp. 223-260). — The purpose of these investigations was to 

 determine whether the bacillus of malignant edema is a sharply defined and invari- 

 able species or a group of varieties. The literature of the subject is critically dis^ 

 cussed in connection with an extensive bibliography. 



The author describes in detail a number of types of this organism as determined 

 by morphological, biological, and pathogenic properties. It is concluded that the 

 edema bacillus, like many other bacterial species, forms a group of varieties which 

 may readily be distinguished. The most of the varieties are only slightly or not at 

 all pathogenic. 



A comparison of Klein's yeaet with other pathogenic yeasts, E. Cohn 

 {Centbl. Bakt. u. Par., 1. Abt., Orig., 36 {1904), No. 3, pp. 369-379).— The experi- 

 mental investigations with .pathogenic yeasts are briefly described. Attention is 

 called to the necessity of giving strict heed to the age and other conditions of yeast 

 cultures in studying their biology and pathogenic action. 



Relations of Federal Government to control of contagious diseases of ani- 

 mals, D. E. Salmon (V. S. Dept. Ayr. Yearbook 1903, pp. 491-506). — The work of 

 this Department in preventing the spread of contagious diseases of animals is out- 

 lined with notes on the diseases to which most attention is given, the necessity of the 

 control of contagion by the Federal Government, and the results obtained. Particular 

 attention is given to the discussion of sheep scab, cattle scab, and Texas fever. 



Report of the veterinarian, L. Van Es {North Dakota, Sta. Rpt. 1903, pp. 1. '4-131, 

 pis, 3, figs. 4)- — During the short time the veterinarian has been connected with the 

 station his work has consisted of field and laboratory investigations on various live- 

 stock diseases. 



Some active work has been begun, particular attention being paid to the scab or 

 scabies among station cattle. As the conditions at the station are in a large degree 

 similar to those prevailing throughout the State, the methods adopted are described 

 at length. The treatment consists of dipping animals, for which purpose two types 

 of apparatus are in use; one for large herds where the animals are driven through 

 the vat. the other for use on a smaller scale, which consists of a small vat in the 

 ground and movable cage in which the animal is placed and lowered into the tank. 

 The dipping fluid used was a lime and sulphur mixture. 



In cooperation with the assistant botanist, experiments were begun to study the 

 effect of the ingestion of Zygadenus elegans on animals. A number of cases of stock 

 poisoning have been attributed to this plant and investigations were conducted with 

 a view to determining its poisonous properties. Only a small quantity of the plant 

 could be obtained when the work was done, but with this rabbits were fed or received 

 hypodermic injections of extracts made from the plant. In most cases negative 

 results were obtained and efforts will be made to continue experiments not only on 

 rabbits, but cattle and sheep during the coming season.
