4 06 EXPERIMENT STATION RECORD. 



guinea pigs, that the resistance of the diphtheria toxin was rather different toward 

 the diphtheria bacillus and bacillus of anthrax. A long series of experiments were 

 made to determine the effect of these bacilli upon the toxin of tetanus. 



Asa general result of the experiments reported in this paper, it is concluded that 

 the action of bacteria upon toxins is variable and depends upon the organisms and 

 toxins concerned. The diphtheria bacillus destroys the diphtheria toxin, but increases 

 the virulence of the tetanus toxin. On the other hand, anthrax bacillus destroys 

 tetanus toxin but intensifies the toxin of diphtheria. Apparently the destruction of 

 the tetanus toxin by the anthrax bacillus is due to the direct action of the bacillus 

 upon the toxin. Old tetanus toxin attenuated by simple contact with the air and 

 light, and especially toxin which has been subjected to the action of the anthrax 

 bacillus, still retains a certain toxic property, although the power of producing 

 tetanus has been lost. 



Annual report on progress in the study of pathogenic micro-organisms, 

 P. von Baumgarten and F. Taxgl ( Jahresber. Fortschr. Lehre Path. Mikro-orgun., 18 

 {1902) , 1. Abt., pp. 368). — As usual in these annual reports the present volume contains 

 brief abstracts of text-books, compendiums, and original treatises on the various patho- 

 genic micro-organisms, whether bacteria, fungi, or protozoa. Detailed classified 

 bibliographical lists are presented at the beginning of each section of the volume. 



A text-book upon the pathogenic bacteria, J. McFarland (Philadelphia: 

 W. B. Saunders A- ('v., 1904, 4- ed., pp. 629, Jigs. 153). — This is a revised and enlarged 

 edition of the author's text-book on pathogenic bacteria. The subjects discussed in 

 the volume include the biology of bacteria, infection, immunity, disinfection, culti- 

 vation of bacteria, experimentation upon animals, and other general bacteriological 

 topics, together with detailed accounts of the organisms concerned in the production 

 of various diseases of man and animals, including pneumonia, tuberculosis, glanders, 

 actinomycosis, tetanus, rabies, anthrax, chicken cholera, hog cholera, swine plague, 

 malignant edema, black leg, etc. 



Bacteriological studies, B. Galli-Valerio (Centbl. Bakt. u. Par., 1. Abt., Orig., 36 

 (1904), No. 4, pp. 465-471, figs. 6). — Detailed notes are given on the growth and 

 behavior in various culture media of Corynebacterium vuccinse, Bacterium diphtheria 

 amum, and B. candidus. It was found during a study of roup in fowls that the roup 

 organism was very susceptible to the action of lemon juice and that nearly all infected 

 birds treated by repeated doses of this substance recovered entirely. 



Veterinary police ordinance of March 3, 1904 (Min. Int. [Italy], Qrd. I'd. 

 Vet., Mar. 3, 1904, pp- 20, pis. 3). — A copy is given of an ordinance of the veterinary 

 police under the Minister of the Interior of Italy for the prevention and control of 

 hifectious diseases among animals. 



Veterinary dictionary, II, P. Oagny and H. J. Gobert (Dictionnaire reierinaire. 

 J'aris: I. B. Bailliere &• Sons, 1904, vol. 2, pp. 854, pis. 4, figs. 933).— This constitutes 

 the second volume of the author's veterinary dictionary and completes the work. 

 It includes all material arranged in an alphabetical manner from I to Z. 



Directions for meat inspectors, E. Ostertag (Leitfaden fur Fleischbeschauer. 

 Berlin: Richard Schoez, 1904, pp- XIV+314, figs. 176). — The purpose of the present 

 volume is to furnish information for persons without a veterinary training concerning 

 the more common pathological conditions met with in meat inspection, and also con- 

 cerning the normal appearance of various parts and organs. Chapters are devoted 

 to the legal foundation of meat inspection, the training of meat inspectors, methods 

 of butchering, infectious diseases, animal parasites, preservation and sterilization of 

 meat, etc. 



Statistics on German meat inspection, R. Edelmann (Deut. Tierarztl. Wchnschr., 

 IS (1904), No. 41, pp. 405-408). — Brief notes are given on the methods of preparing 

 the statistics obtained from the inspection of animals and meat in abattoirs, and
