1, pp. 16-28). — Egg white was introduced into animals and the blood and tissue 

 extracts from them tested for its presence by sensitizing guinea pigs. 



The work shows that egg white injected into the stomach, rectum, or 

 l)eritoneal cavity of a rabbit may be, in part at least, absorbed unchanged. 

 Egg white injected intravenously in rabbits quickly disappears from the cir- 

 culating blood, but may subsequently be detected in the peritoneal cavity, and 

 by the sensitization test in certain organs. It may also be detected in the bile. 

 When carried into the tissue after intra venotis injection it may be washed back 

 into the blood current by transfusion with salt solution. The injection of egg 

 white intravenously in rabbits decreases after a few hours the total protein in 

 the blood, but injection in large amount proves fatal. 



Biolog'ical difiEerentiation of the protein of mice and various species of rats, 

 F. Graetz {Ztschr. Immunitdtsf. u. Expt. Ther., I, Orig., 6 (1310), No. Jf, pp. 

 627-6/f3; abs. in Zenthl. Gesam. Physiol, ti. Path. Stoffwechscis, n. scr., 6 {1911), 

 No. 1, p. IS). — It is not possible, according to the author, to differentiate the 

 proteins of the various species of rats (litis decunwnus, M. rattus, and white 

 i*ats) with the precipitin and complement-binding or fixation and anaphylaxis 

 reactions. On the other hand, however, it is possible with the complement- 

 binding and precipitation methods to differentiate the protein from the various 

 species of rat from that of the white mouse. 



Anaphylaxis with plant substances, T. Azuma (Beitnige zur pflanzlichen 

 AndphyUidh'. Disti., Osaka, 1010 ; abs. in Ztschr. Immunitdtsf. u. Expt. Ther., II, 

 Ilcf., 3 (1910), No. 11, p. 996). — Anaphylaxis is not so easily produced with 

 plant antigens as with animal antigens. The expeiiments, which were con- 

 ducted with soy beans, horse beans (Vicia faba), rice, and barley, show that 

 anaphylaxis can be produced by giving either one large initial dose of the 

 antigen or repeated small doses. 



Precipitating characteristics of plant antigens, T. Azuma (Beitrdge sum 

 Studium dcr prdzipHierrndcn Elgcnschaftcn pflanzHchcr Aiitigcne. Diss., Osaka, 

 1910; abs. in Zt.schr. Immunitdtsf. u. Expt. Ther., II, Rcf., 3 (1910), No. 11, p. 

 99.'f). — Seed and seed-germ extracts from rice, barley, horse beans (Vicia faba), 

 and soy beans are capable of producing precipitins. The normal sei'a of various 

 animal species were found to give a precipitation with these plant extracts. The 

 precipitin-forming substance of the plant extracts is destroyed by autolysis. 

 The precipitinogens are weakened by a temperature of 60° C, and absolutely 

 checked at 80°, but at 100° they are revived. 



The action of some lipoid substances upon ultrafilterable viruses, Y. 

 FuKUHARA (Ztschr. Imniunitiitsf. u. Expt. Ther., I, Orig., 9 (1911), No. 1, pp. 

 75-86).— Oleic acid was found to exert a strong destructive action upon all 

 viruses, including chicken pest vaccine virus and the virus of rabies. Sodium 

 and potassium oleate and lecithin, however, did not possess such a capacity, 

 save for the virus of rabies. The bactericidal action of pyocynase, according to 

 the author, is probably due to the presence of an alcohol-soluble lipoid sub- 

 stance which, when isolated, is more powerful than the original pyocynase. 

 Coli lipoids did not have any effect upon the various viruses. 



Methemolytic reactions, O. Bail and S. Suzuki (Ztschr. Immunitdtsf. u. 

 Expt. Ther., I, Orig., 9 (1911), No. 1, pp. 42-60). — A specific prepared solution 

 of sensitized blood corpuscles , is still capable of fixing large amounts of hemo- 

 lytic immune bodies in the same manner as intact sensitized blood corpuscles. 

 From this it appears that the hemolysis which goes on between the blood 

 corpuscles and the serum does not go on to the final reaction, but simply acts 

 as a preparer or an accompanist for the reacting substances contained in the 

 blood corpuscles. This is termed by the author, " methemolysis." The excessive 

 fixation of immune bodies by the blood corpuscles, which are not necessary for
