598 EXPEKIMENT STATION RECORD. 



tures of anthrax bacillus which had been maintained for 1 j years upon a 10 per cent 

 gelatin medium at the living temperature, and which had been transferred at inter- 

 vals of 2 or 3 months during this time, lost the jiower of liquefying gelatin to such an 

 extent that this process took place only to a slight degree after 50 days. The anthrax 

 cultures which had lost this characteristic of liquefying gelatin remained as virulent 

 as other anthrax cultures. The power of liquefying gelatin gradually returned after 



4 to 6 transfers upon agar medium at a temperature of 37° C. 



Th.e practical ■working- of reg-ulations for combating foot and mouth disease 

 {ArcJi. lA'ut. Lmid/r. liuths, J4 [rjoO), }ip. ..'4-^--'74)- — After a discussion uf the ])r<)hlem 

 at the twenty-eighth meeting of the German Agricultural Conunission, it was 

 resolved that the present regulations regarding this disease are not well adajjted to 

 prevent the spread of the disease, and that at the same time they work unnecessary 

 hardships upon certain stock owners and shippers. It was further resolved that a 

 commission be selected to report upon more suita})le regulations regarding this matter. 



Contribution to the study of antileucocyte serums — their action upon the 

 coagulation of blood, C. Delezenne {Cornpt. Rend. Acad. Sci. Paris, 130 {1900), 

 No. 14, pp. 938-94-0). — The author's experiments were conducted on dogs and rab- 

 bits. It was found that the antileucocyte serum when mixed with the blood of the 

 dog in a glass vessel hastened the process of coagulation. When injected directly 

 mto the circulation the serum had the opposite effect. 



Antirabies vaccinations at the Pasteur Institute in 1899, E. Viala {Ann. 

 Imi. Paskur, 14 {1900), Xo. 7, pp. 4S7-491) .—Briei notes on the history of the 1,614 

 cases treated, including o])servations on the rabid animals. 



A parasite the supposed cause of some cases of epilepsy, G. H. French 

 {Canad. Ent., 32 {1900), No. 9, pp. 263, 264, fig. !)• — Gastrophilus epilepsalis is described 

 as a new species, which was found in great numbers in the intestines of a boy suffer- 

 ing from epileptic spasms. After a prolonged anthelmintic treatment the boy recov- 

 ered, and it is believed by the author that this species was the direct cause of epilepsy, 

 It is not i^ossible to determine in this case the origin of the infestation. 



Statistics on parasites of slaughtered animals of European Russia, Sibe- 

 ria, and the Caucasus for 1896 and 1897, G. Gueix {Izv. MoscfMr SehkoMiOz lust., 



5 {1899) , No. 3, pp. 234-283). — These statistics are taken from the reports of 40 slaugh- 

 terhouses and cover 1,959,688 cattle, 149,329 calves, 1,479,923 sheep, 510,842 hogs, 

 and 13,036 horses. The most common parasite in all these animals was Txnla echi- 

 noccocus. The liver fluke was the second most frequent in adult cattle, calves, and 

 sheep. Other parasites which occurred with more or less frequency were T. medio- 

 canellata, T. dentlculata , T. expanm, Sirongiilus parado.rus, S. micrurus, S. filaria, S. 

 contortus, Ascaris megulocephala, and Trichina .spiralis. — p. fireman. 



G-regarines and the intestinal epithelium, L. Leger and O. Duboscq {Compt. 

 Rend. Acad. Sci. Paris, 130 {1900), No. 23, pp. i5(56-i56<?).— The author made a study of 

 the life history of gregarines in the alimentary tracts of insects. The study was prin- 

 cipally confined to Anthrenus museorum and (xryllus do7ne.slicus. In the intestines of the 

 former species the gregarine P(/.rm/rt ?ho6ms2/ was found in abundance, while Diplocyslis 

 major was the common species in the intestines of the cricket. The author was unable 

 to find these species inside the epithelial cells during any stage of their development. 



Nodular disease of the intestines of sheep, D. Hitcheon {Agr. Jour. Cape 

 Good Hope, 17 {1900), No. 2, lyp. 89-91). — The author made a study of this disease of 

 sheep. It is stated that no remedies are known which will kill the embryo worms 

 in the intestinal nodules and restore the intestines to a healthy condition. It is pos- 

 sible, however, to expel the worms from the intestines by the use of cathartic remedies. 



Worms in sheep {Jour. Agr. and Ind., South Australia, 4 {1900), No. 1, pp. 22-26.) — 

 Brief notes are given on nematode worms in lambs, together with a discussion of the 

 more approved remedies for ridding lambs of these parasites, and methods of pre- 

 venting infestation.
