82 EXPERIMENT STATION RECORD. [Vol.36 



Quasi-continuous temperature records in healthy and tuberculosus bovine 

 animals, especially in relation to the tuberculin test, P. C. V. .Tones and G. S. 

 WooDHEAD (Jour. Compar. Path, and Ther., 28 (1915), No. 4, pp. SS7-S57, figs. 

 16). — The authors describe in detail a specially constructed apparatus for ob- 

 taining continuous temperature records in bovines. The apparatus consists 

 essentially of a modified platinum electrical resistance thermometer encased ia 

 a silver tube with the coil connected by means of comparatively heavy flexible 

 leads composed of a series of strands of copper wire to the Wheatstone bridge, 

 on which the resistance (and temperature) is measured by means of the deflec- 

 tion of a galvanometer. 



A .special harness for holding the thermometer in place so that the animal is 

 free to assume any position has also been devised and is described. 



Normal (winter and summer), pre-tuberculin period, post-tuberculin period, 

 and late post-tuberculin period temperatures taken in the vagina by the appa- 

 ratus described are submitted in graphical form. 



The diastase in the saliva of the ox, C. C. Palmer (Amer. Jour. Physiol., 41 

 (1916), No. 4, pp. 483-491). — From experiments conducted at the veterinary 

 research laboratories at the Minnesota Experiment Station it is concluded that 

 the saliva of the ox contains a starch-splitting enzym or enzyms, the amount 

 varying in individuals and at different times in the same individual. This 

 enzym (or enzyms) is not a specific constituent of the saliva, but comes from 

 the blood, which contains the same or similar enzyms in much higher concentra- 

 tion. The enzyms are destroyed when subjected to a temperature of about 

 65° C. for 1 minute. The enzym (or enzyms) is deemed to be unimportant so 

 far as digestive ability is concerned. 



An attempt to use pilocarpin hypodermically to stimulate salivary secretion 

 was unsuccessful on account of the diastatic power of the pilocarpin on the 

 starch. The procedure used in the experiments described was to irrigate the 

 mouth with water or a dilute solution of acetic acid followed by inhalations of 

 strong acetic acid. 



The blood serum used was obtained by bleeding from the jugular vein in the 

 usual manner. 



A simple method of obtaining serum for the agglutination test from cattle 

 suspected to be suffering from contagious abortion, L. E. W. Bevan (Jour. 

 Compar. Path, and Ther., 28 (1915), No. 4, pp. 277-280, figs. 2).— A tube for 

 collecting blood for serological work which has been found to be superior to the 

 usual pipettes used is described. 



For preserving blood samples which are to be sent some distance for exami- 

 nation a preservative containing 3 gm. of boric acid and 0.9 gm. of sodium 

 chlorld in 100 cc. of distilled water was found to yield satisfactory results. If 

 it was desired to prevent coagulation the pre.servative solution described, but 

 containing in addition 3 gm. of sodium citrate, was used. 



The death and expulsion of the immature fetus as a standard for measur- 

 ing the prevalence of cattle abortion, W. L. Williams (Jour. Amer. Vet. Med. 

 Assoc, 50 (1916), No. 1, pp. 29-40). — A paper presented at the annual meeting 

 of the American Veterinary Medical Association at Detroit, Mich., August 22, 

 1916. 



The outlook for the control of cattle abortion, W. L. Williams (Jour. Amer. 

 Vet. Med. Assoc, 49 (1916), No. 2, pp. 199-217).— A further discussion of this 

 subject (E. S. R., 34. p. .*586). 



Case reports of lymphangitis in cattle caused by an acid-alcoholic-fast 

 organism, .T. Tkatim (Jour. Amer. Vet. Med. Assoc, 49 (1916). No. 2, pp. 254-257. 

 pi. 1). — lleports are given of cases of lymphangitis of cattle which showed the
