cord was found to be of a black color throughout with extension of thi.s pathological 

 condition into the nerves for some distance from the spinal cord. The brain mem- 

 branes were thickened and covered with a dark-colored fluid. 



Lead poisoning of cattle, R. H. Forbes and W. W. Skinner (Arizona Sta. Rpt. 

 1904, pp. 497, 498). — Numerous fatalities occurred among cattle after drinking water 

 from the tailings of a quartz stamp mill. An analysis of this water showed a faint 

 trace of arsenic, somewhat more copper, and 2.64 to 3.21 per cent of lead in the form 

 of white carbonate. The symptoms observed in the poisoned animals were those 

 which are produced by lead, and it is believed that the carbonate of lead was the 

 cause of death. 



Malignant edema, V. Schaefer (Amer. Vet. Rev., 28 (1904) , No. 4, pp. 364-367). — 

 An outbreak of this disease occurred on a farm near Herman, Nebr., and affected 

 both horses and cattle. Large edematous swellings were observed on the anterior 

 portion of the thorax. Affected horses were treated with iron and quinin, but died 

 within the course of 2 days. Several years later an outbreak of the disease occurred 

 in the same locality among cattle. The swellings on affected cattle were of large 

 size. The author tried potassium iodid in half-ounce doses 3 times daily and made 

 external applications of corrosive sublimate. The doses of potassium iodid were 

 increased and maintained for a number of days. After a time symptoms of iodism 

 appeared, after which the treatment was omitted for 2 or 3 days. The remedy was 

 then applied again and continued until complete recovery took place. 



The bacillus of malignant edema, E. Bachmann (Centbl. Bald. u. Par., 1. Abt., 

 Orig., 37 (1904), Nos. 2, pp. 221-228; 3, pp. 353-364). — A careful study was made of 

 the morphology, biology, and pathogenic properties of the bacillus of malignant 

 edema. During the author's experiments a number of races of this organism were 

 used in inoculating guinea pigs and rabbits. For this purpose cultures were main- 

 tained on agar and liquefied gelatin. The 5 races of the bacillus which were used by 

 the author would naturally be classified in 2 groups containing 3 and 2 races, respec- 

 tively. The first group when inoculated into rabbits and guinea pigs produced sera 

 which agglutinated bacilli of the same race and which also possessed a weak agglu- 

 tinating power toward other races of the same group. In the races belonging to the 

 second group no pronounced agglutinating serum was obtained during the author's 

 experiments. It is believed that the ordinary bacillus of malignant edema and the 

 bacillus described by Ghon and Sachs are identical and the term bacillus of malig- 

 nant edema is, therefore, retained as a group name. 



Etiology and treatment of azoturia, B. M. Flint (Amer. Vet. Rev., 28 (1904), 

 No. 2, pp. 146, 147). — Brief notes are given on the symptoms of this disease. In 

 treating azoturia the author administers eserin or arecolin, followed by a mixture 

 containing fluid extract of jaborandi, fluid extract of buchu, sweet spirits of niter, 

 and cold water. The fluid extract of jaborandi is considered a drug of great value 

 in combating the symptoms of azoturia. 



Diseases of sheep in Great Britain (Jour. Bd. Agr. [London], 11 (1904), No. 

 8, pp. 490-494). — During the spring of 1904 reports were received by the board of 

 agriculture which indicated that sheep diseases were perhaps unusually prevalent on 

 account of the previous wet season. A circular letter of inquiry was, therefore, 

 addressed to a number of correspondents and replies were received from which 

 considerable information was gained regarding the nature and prevalence of sheep 

 diseases. In general, the health of sheep was found to be in fairly satisfactory con- 

 dition. The death rate in most of the localities was not above the average. Notes 

 are given on the occurrence of liver fluke, foot rot, louping ill, blackleg, scour, and 

 joint ill. In the replies to the circular letter it was stated that in some localities 

 scour is very fatal and widely distributed in certain seasons. 



Treatment of petechial fever -with Ichthargan, Brugger ( Dent. Tierarztl. 

 Wchnschr., 12 (1904), No. 47, pp. 470-472). — The symptoms and course of a case of 

 this disease in the horse are described in considerable detail. A 2 per cent solution of
