organisms. When a double amount of pigeon serum was employed the bac- 

 tericidal action against the anthrax bacillus was increased, while the use of a 

 double amount of leucocytes had no effect whatever. 



The bactericidal action when present in Wright's mixture is, therefore, only 

 a transitory one and is probably due to the serum only. 



The value of the specific anaphylaxis reaction for the biological differen- 

 tiation of proteins, B. Bachrach (Vrtljschr. Gerichtl. Med. u. Offentl. Sani- 

 t(itsiv., 3. sen, ^0 {1910), No. 2, pp. 235-271; ahs. in Chem. Abs., 5 (1911), 

 No. Jf, p. 720). — This is an investigation of the quantitative value of the ana- 

 phylaxis reaction, the effect of diphtheria toxin on the sensitization, the spe- 

 cificity of the phenomenon, the differentiation of proteins of closely related 

 species and chemically different proteins fi*om the same species, and the action 

 of normal serums when injected intravenously. 



It was found that diphtheria toxin when injected at the same time with an 

 extract from a blood spot for sensitizing purposes increases the sensitization 

 but decreases the specificity. The author considers that the reaction can not, 

 therefore, for the present at least, be considered seriously for medicolegal pur- 

 poses. It was also found that the serum from a monkey could not be posi- 

 tively differentiated from human serum, nor was the author able to differentiate 

 the serum protein of a cow from the casein or albumin of cow's milk. 



A contribution to the question of the bacterial content of the muscles 

 of healthy and diseased animals which, come to slaughter, A. Horn {Ztschr. 

 Infelctionskrank. u. Hyg. Haustiere, 8 {1910), No. 6, pp. ^24-^37; ais. in Centhl. 

 BaM. [etcl, 1. Ait., Ref., J,9 {1911), No. 8-9, pp. 2^7, 2.^8).— This work shows 

 that the muscles of healthy, recently slaughtered animals can contain bacteria, 

 but they are as a rule present in only very small amounts and can in most 

 instances be detected only by enriching methods. The bacterial content of the 

 muscles of diseased animals stands in no relation to the extent of the disease. 

 The author recommends examining the spleen of animals affected with septi- 

 cemic diseases. 



The spontaneous occurrence of Bacillus enteritidis (Gartner) in mice, 

 and the significance of the meat-feeding test with white mice, G. F. Berg 

 (tjber spontanes Vorlcommen von Ententidis-Gdrtnor-BazUlen hci Mdusen und 

 die Bedcutung des Fleischfiitterungsversuches an Weisse Manse. Inaug. Diss., 

 Gie^sen, 1910, pp. 30; abs. in Centhl. Bakt. [etc.], 1. AM., Ref., J,9 {1911), No. 

 8-9, pp. 2^8, 2.'i9). — Mice, according to this author, when inoculated intraperi- 

 toneally and subcutaneously with B. enteritidis (Giirtner), are killed, but 

 when fed i^er mouth remain alive. When sound meat was fed the animals 

 died in the same space of time as others which were fed diseased meat. 



In regard to the occurrence of micro-organisms in the conjunctival sac 

 of horses and bovines, F. Karsten ( tJher das Vorkommen von Mikroorgan- 

 ismen inv KonjimktivaJsacke des Pferdes und Rindes. Inaug. Diss., Univ. 

 Giessen, 1910, pp. 53, pis. 3; abs. in Gcntbl. Bakt. [etc.'], 1. Abt., Ref., 49 

 {1911), No. 5, pp. 135, 136). — The conjunctival sac of the horse and bovine 

 almost always contains micro-organisms, which are variable in number. The 

 white micrococci and the xerosis bacillus are almost invariably present, the 

 former in greater amount. Bacillus subtilis, Micrococcus aureus. Bacterium 

 pseudoconjujictivitidis, M. roseus, M. siilfureus, M. aurantiacus, M. flaxms. 

 Streptococcus lanceolatus, and Bacterium pyocyaneum are present occasionally. 



Sacculated kidney, perinephritis and intranephritis, subcapsular cysts in 

 domesticated animals, F. W. Hagemann {Arcli. Path. Anat. u. Physiol. [Vir- 

 choiD], 202 {1910), No. 2, pp. 2U-266, figs. 8).— The author describes the 

 patho-anatomical and histological findings of the above conditions in bovines 

 (including galves), bogs, »nd horses.
