VETEKINARY SCIENCE AND PRACTICE. 391 



The authcn- gives a detailed description of \'arious bacteriological 

 apparatus upon which improvements have been made, including a tube 

 carrier for a hand centrifuge, a thernio-regulator, sterile pipette for 

 plate cultures, and a test-tube holder. Notes are also gi^'en on the 

 use of the platinum loop and on methods of detecting tubercle bacilhis 

 in tissues. 



Results of the Lorenz method of inoculation against hog cholera 

 ■with Prenzlau vaccine during the years 1897-1899, E. Jokst 

 and A. Helfeks {Berliv. Tierdrtl. Wc/tnsc/ir., 1900, x\v>. 11, j)j?. liil- 

 12Ji). — The number of hogs inoculated was 217,376. In general the 

 inoculations were endured by the hogs without any disturbance of the 

 general health conditions. The number of deaths which were attributed 

 to inoculation by thi.s method was 40, of which 31 cases were not care- 

 fully investigated. One case showed necrosis of the cervical ligament, 

 3 erysipelas of the head, 1 peritonitis, 1 articular inflanunation, and 2 

 gastro-enteritis. The number of cases of hog cholera which developed 

 in consequence of the injection of cultures was 202. In these cases the 

 disease was manifested within from 2 to 7 days after the inoculation. 

 Sixty-four of these cases recovered spontaneously. The inoculation 

 failed to produce a sutiiciently complete immunity in 155 cases which 

 became later infected with the natural disease. The question whether 

 inoculated hogs transmit the disease to uninoculated hogs was answered 

 in the negative in nearly all the reports. Of the hogs which were 

 suffering with hog cholera, 68. S per cent were cured by the method. 



Partial paralysis and crippling of sTvine, J. H. Reed and G. E. 

 Day {Oittario Agi'. Col. and Expt. Farm Bal. 110, pp. 8-l'2). — During 

 the winter and spring months many pigs become somewhat paralyzed or 

 lame from an apparent rheumatic affection. In paralysis the appetite 

 is variable and the hind limbs are so affected that locomotion is scarcely 

 possible. In rheumatic affections the symptoms are similar to those 

 of paralysis, with the exception that the joints are frequently swollen 

 and sensitive. This form of paralysis is usually the result of digestive 

 disturbances associated with constipation. These digestive troubles 

 are due to overfeeding or improper feeding and lack of exercise. The 

 rheumatic troubles are mostly caused by improper l)uildings, poor 

 ventilation, or damp sleeping places. 



The curative treatment for these affections consists largely in cor- 

 recting these faults in diet or surroundings, the use of a tonic, such as 

 nux vomica, and suitable purgatives. Under the head of "Correc- 

 tives," the author refers to substances which are not strictly foods, 

 but which assist in bringing about a normal digestive action. Among 

 these substances may be mentioned fresh earth, ashes, and charcoal. 

 Suggestions are given as to proper plans for building the piggery, so 

 that damp floors may be avoided and proper \entilation secured.
