trary, many facts to support the assumption that there is no causal relation whatever 

 existing between this malady and the so-called cornstalk disease of cattle." 



The horse's teeth, E. P. Nilks (Firghna Sta. Bui. 36, pp. 7). — This consists of a

 tious of animals slaughtered.

 Sta. Bui. 13, 2d ser., pp. 7). — This bulletin consists of a general discussion of tuber- 

 culosis and glanders, and a statement of the diagi ostic value of turberculin and 

 niallein. 



Contribution to the knowledge of the streptococci of yellow^ "gait," L. 

 Adametz {Jour. Landw., 43, Xo. 3, pp. 231-241). — A study of tlie microorganisms 

 occuring iu the milk of cows affected with a form of udder inllammatiou common 

 in Switzerland under the name of gelbe gait. 



DAIRYING. 



Contribution to tliG study of the colostrum of the cow, V. 



HouDET {Ann. Inst. Fasteur, 6' {H^'Ji), Xo. 7, pp. oOiJ-'jlS). — As iir.st 

 ])ointed out by Lassaigne^ the formation of colostrum proper is pre- 

 ceded by the secretion of an albmiiinous litjuid whicli sometimes begins 

 to form 2 montlis before parturition. Tliis secretion often appears 

 under 2 forms — a brownisli, viscous, honey-lilie product, and a lemon- 

 yellow, non- viscous ]i{|uid, although the two are not always distinct and 

 often coexist in the same animal, the earlier milkings furnisLing- the 

 first, the later milkiiig's the second. Examinations of samples of the 

 viscous secretion showed it to be curdled by heating and precipitated 

 by acetic acid, biclilorid of mercury, and alcohol, but not curdled by 

 rennet. It was absolutely free from fat, and it contained traces of 

 mineral matter, G.'llJ: per cent of water, 22.74 per cent of albuminoids 

 soluble in water (to the extent of passing a Chamberland filter), and 

 14.12 iier cent of albuminoids insoluble in water. The fluid secretion 

 contained less water and less soluble albuminoids than the viscous 

 secretion, and gave a barely appreciable precipitate with biclilorid of 

 mercury and alcohol, but behaved in the same manner as the latter
