CO.. or 20 cts. for enouiili to viR'cin:il(> a suckling pig. . . . Tlie virulent blood 

 which forms ii part of the vaccine will probably sell at ai)i)ro.\iniately 1 ct. per 

 cc. This will add from 1 to 3 cts. to the cost of each dose when the simulta- 

 neous method is used. The cost of vaccinating a hog weighing 100 lbs. at 

 this rate would be about 42 cts. at the present cost of production. But when 

 the serum is produced on a much larger scale, and we have improved our 

 methods and learned to economize to the best advantage, the carcasses of hogs 

 used up in Qur work, we exi)ect to produce this vaccine for perhaps 25 cts. for 

 a full dose. At 40 cts. or even at 50 cts. a dose the dose would be very cheap 

 for herds of exposed pure-bred hogs and for use in checking outbreaks." 



Methods of controlling' hog cholera, M. H. Reynolds (Northwest. Agr., 2.'i 

 {190D), Xos. 8, p. l'J.3; 10, pp. J'i7, 2-'iS). — In this address, which was presented 

 before the Minnesota Live Stock Breeders' Association, the author reviews the 

 present status of our knowledge of hog cholera and discusses the investigations 

 of the station noted above. 



Studies of conditions relating to catalepsy of swine, C. H. Hansen 

 (Mdancdstcr. Dyrhnjvr, 20 (I'JOS). Xo. 13, pp. 333-360; ahs. in HoariVs Dairy- 

 man. J/O (1009), Xo. 1, p. 10). — The report gives data relative to investigations 

 along the following lines of study: The influence of cod-liver oil on the quality 

 of pork, the poisonous effect of pliosphorized cod-liver oil in the case of healthy 

 swine, the influence of phosphorized cod-liver oil on the deposition of lime salts 

 in the organism, and the keeping quality of phosphorized cod-liver oil. 



Some colic cases in town horses, H. Lomas {Vet. Rec, 21 {1909), No. 1070, 

 pp. Ji.'il--'i-'f3). — This account is based upon 1,244 cases among general work 

 horses. 



The author considers the increased work during certain months and poor 

 provender the important causative factors. That there is a direct relation be- 

 tween hard work and death from twists and volvulus he considers quite evi- 

 dent. The death rate is considered as very largely controlled by the age of the 

 horses and the work exacted. " Old horses— horses over 3i years' service — have 

 colic, but the death rate is very low indeed as compared with those of shorter 

 service." The majority of the twists have been at the commencement and 

 termination of the large colon. 



Glanders, W. Hunting {London, 1908, pp. 100+4, pis. l.'f). — In this work the 

 author first considers the history of glanders and then deals with its distribu- 

 tion and prevalence, etiology, symptoms, post-mortem appearances, diagnosis, 

 cure and recovery, prevention, and legislation. An appendix is devoted to 

 glanders in man. 



Observations indicating that the recent outbreak of diphtheria in the 

 wood-pigeon (Columba palumbus) is caused by a filter-passer, G. Dean and 

 W. K. Marshall {Jour. Path, and Baet., 13 {1908), No. 1, pp. 29S3).— From 

 inoculation experiments here recorded it appears that an extract of the mem- 

 brane after filtration through a Berkefeld filter still contains the virus. This 

 reproduced the disease when inoculated upon the throat, whereas when sub- 

 cutaneously inoculated an acutely fatal disease without any definite pathologi- 

 cal lesions was produced. 



Note on the prevalence of intestinal worms in dogs in Cambridge, G. II. F. 

 XuTTALL and C. Strickland {I'arasitologi/, 1 {190S), No. 3, pp. 261, 262).— In 

 the course of investigations conducted at Cambridge, England, upon dogs in- 

 fected with riroplasma canis 24 were examined for intestinal parasites. All 

 were found to harbor worms. Of the 3 species of parasites found, 17 dogs 

 harbored Ascaris inystax, 14 harbored Dipylidium. caninwm, and 4 harbored 

 Twnia scrrata. The number of A. inystax per dog varied from 1 to 113, while 

 D. caninuni varied from 1 to 102, and T. serrata from 1 to 8. The total number
