An epizootic nianimitis of sheep caused by bacteria, Dammann and 

 Freese (I)riit. Ticnirztl. Wchnschr., 15 {lOdl), Xo. 12, PU- li!'>-170).—An epi- 

 zootic mamniitis was observed in sboep on an estate where it bad prevailed for 

 a muiii>er of years. The disease conunonly appeared in ewes when tbe lambs 

 were al)out 4 to (j weeks old. A bacterial organism was isolated from tbe udder 

 of affe'cted ewes and jiroved to be pathogenic when injected into tbe udder of 

 healthy ewes. When, however, healthy ewes were kept in tbe same pen with 

 diseased animals the infection did not sjiread. Notes are given on the behavior 

 of tbe pathogenic micro-organism on various nutrient media. 



A note on the inter-comniunicability of ovine and caprine variola, W. H. 

 Floor {^'rt. Rec. 19 (1907). Xo. 91 S, p. G'/S). — Brief mention is made of in- 

 stances in which variola has I»een observed to spread from sbeep to goats, or 

 vice versa. Attention is called to the fact that in insi)ecting sbeep or goats for 

 the possible jiresence of variola, the brisket should always 1)6 carefully examined. 



The histology and physiology of normal pigs' blood, W. Giltner (Jour. 

 Compar. Path, and Titer., 20 (1907). Xo. 1, pp. 18-23).— As a basis for the study 

 of the reactions of the blood in disease, it is necessary to establish be.vond dis- 

 pute all of the normal conditions which may be found in the blood. The au- 

 thor's observations along this line were undertaken to determine the relative 

 number of red and white blood corpuscles, the specific gravity of tbe blood, the 

 size of the red blood corpuscles, and other points. During this study, tbe blood 

 of ii4 normal pigs was studied and tbe results of tbe observations are presented 

 in a tabular form. 



Increasing the resistance in protective vaccination against swine erysip- 

 elas, M. I*RETTNER (ZtscJif. fllfcJxtioilshTdllk. II. HlKJ. Hd ii.'nt icfc. 2 {1907), Xo. 

 -i--j< VV- 3').3-3')9). — According to the experiments reported in this paper the 

 resistance of the anim.-.l organism toward swine erysipelas becomes higher 

 tbe more active the part taken by the organism in tbe jirocess of imnnniity. 

 Tbe degree and duration of this I'csistance aiijiarently depends upon the rela- 

 tion between the (piantity of seriun and culture used in the siuuiltaneous 

 method. The smaller tbe quantity of serum tbe more pronounced the active 

 imuauiity which results. In the author's opinion tbe simultaneous method of 

 vaccination for swine erysipelas produces an essentially passive innnunity. 



Trichina inspection in southei'n Germany, .J. Bohm (WclnixcJir. TicrhcUlc. 

 II. \ irjiziiclit, -jI {1907), Xo. 12, pp. 221-22()). — It has been commonly reported 

 that hogs affected with trichina are exceedingly common in southern Germany 

 and that the disease is almost unknown in man in that region. In the author's 

 ojtinion this condition of affairs no longer prevails. Notes are given on a number 

 of outbreaks of trichina among hmnan beings and recommendations are made 

 regarding the sanitary supervision of farms in order to prevent the infestation 

 of hogs with trichina.

 been already noted (E. S. R., IS, i>. ."iS-'V). The present volumes contain an 

 account of ring worm, mange, and some of the intestinal parasites of the horse 

 and a detailed discussion of the structure and diseases of the bones and muscles. 

 Si)ecial chai)ters are given on diseases of tbe .joints and feet, wounds, .materia

Intoxication produced by dead glanders bacilli in the stomach, J. Can-
