Biological proteid difEerentiation with rats and mice, K. Trommsdorff 

 (Arh. K. (Jii>idhtmmt., ^i (lOOV), No. 2, pp. 560-567; ahs. in Bioclicin. ZcntbL, 

 9 (1909), No. 7-8, p. 382). — From this work it appears that it is possible sharply 

 to differentiate the proteid of the rat from that of the mouse by both the pre- 

 cipitin and the complement binding reactions. The anaphylaxin test was not 

 specific. From this it is evident that the mouse and rat are not so closely 

 related biologically as it is generally assumed. 



About the action of imm.urie sera, E. Weil and H. Braun (Folia Serol., 

 3 (1909), No. 7, pp. 271-275; 'Jhs. in Biocltcm. ZcnthL, 9 (1909), No. 7-8, pp. 

 361, 362). — Immune sera are divided into two classes, namely, those which 

 become inactive on treatment with bacteria and those in which the protective 

 action remains unchanged. To the first class belong those which attack bac- 

 terial substance in the same manner as do the bactericidal and the bacterio- 

 tropic sera,- The second group of sera produce no change on the bacterial sub- 

 stance, only reacting toward the secretion products of the bacteria and there- 

 fore being antitoxic and antiaggressive. 



Detection of antigens and antibodies by the deviation of complement, A. 

 MosES (Mem. Inst. Osicaldo Cruz, 1 (1909), p. 109; abs. in Zentbl. Biochcm. u. 

 Biophys., 10 (1910), No. 4, p. iS8).— The author was able by the aid of the 

 complement binding reaction with numerous cases, among them being two cases 

 of spirochetosis of chickens, to detect the antigens and antibodies. With hydro- 

 phobia, variola, and chicken plague the results were in most instances negative. 



Experiments with vaccine, variola, and ovine, L, Voigt (Ztschr. Infektions- 

 l-nnilc. II. IJi/fj. JIaiisticrr. (j (1909), No. 2, pp. 101-116, pis. 5; abs. in Berlin. 

 TicriirzU. Wehnschr., 26 (1910), No. 20, p. /,10).— The results are given of 

 numerous experiments with sheep, monkeys, goats, pigs, and rabbits, in which 

 the author was able to verify Bollinger's belief that vaccination with a foreign 

 variety of pox protects the animal against subsequent attacks of the pox 

 peculiar to the animal itself or against foreign varieties of pox, but does this 

 only incompletely. 



Variola in the monkey had the symptoms common to man (rash, etc.), but 

 was milder in degree. Cattle, sheep, and goats reacted toward variola in the 

 same manner as does the rabbit, i, e., localized fever-free areas of papules, 

 macules, and pustules. The goats and sheep are only partially protected 

 against variola by vaccination. The severer form of variola in the pig, con- 

 trary to the general belief, was not observable. With vaccine the localized 

 areas of fever with the accompanying skin manifestations could be found in 

 the pig and monkey, while with cattle, sheep, goats, and rabbits the skin mani- 

 festations were present without the fever. 



A'accine with the sheep and goat produced only incomplete immunity against 

 a following infection with ovine. Likewise, ovine did not protect completely 

 against subsequent infection Avith vaccine. 



The effect of Pasteur's anthrax vaccination on the meat and milk of the 

 animal, N. Axtoxi (Ueber den Einflus.s der Puxteiir'schen MilzbrnndsrJnitzini- 

 pfunijen auf Fleisch und Milch der oeimppen Ticre. Inaug. Diss. Univ. Bern, 

 1909, pp. 31). — I'rotective vaccination has no effect on the meat of vaccinated 

 animals. Anthrax bacilli could not be detected microscopically or culturally in 

 either the organs or extracts of the muscles. The findings with vaccinated 

 goats, cows, and sheep were similar, and in addition vaccination had no per- 

 ceptible effect on the offspring.
