618 EXPERIMENT STATION RECORD. 



aftor the adiiiinistratioii oi the air. In comparison with the results obtained l)y this 

 nietlioil, tlio author states that in treating the same disease hy the Schmidt method 

 a mortahty of 20 per cent was observed. The author V)elieves, therefore, that the 

 air tri'atment is in cvi'ry way superior to the use of infusions of potassium iodid. 



Notes on hemoglobinuria, Simon {Berlin. Tierarztl. Wchnschr., 1903, No. 4, 

 pp. 51, 52). — The author observed a number of cases of this disease during a general 

 pmctice and describes the most connnon symptoms. As a rule a considerable anemia 

 and emaciation were observed associated with an increase in temperature and a yel- 

 low coloration of the conjunctiva. In the majority of cases death took jilace within 

 a few days. In controlling this disease the author recommends proper drainage of 

 the soil in fields and corrals where cattle are allowed to run, and the free use of such 

 well-drained })astures. 



Ticks and African coast fever, C. P. Lounsbury {Transvaal Agr. Jour., 2 {1903), 

 X(i. 5, p)). 4-l.i). — During the past season the author made a study of this disease in 

 the Transvaal. The term African coast fever is preferred to Rhodesian cattle disease, 

 Rhotlesian tick fever, Rhodesian red water, virulent red water, etc., under which the 

 same disease has been referred to by other writers. The disease is unquestionably 

 different from ordinary Texas fever, but is transmitted by ticks, probably a species 

 of Rhipicephalus commonly known as the brown tick. Notes are given by way of 

 com]ianson showing the methods of transmission of other diseases by ticks and other 

 animal jiarasites. It is of considerable importance to determine definitely just which 

 species of ticks are concerned in the transmission of African coast fever. Experi- 

 ments were made to determine the pathogenicity of Rhipicephalus dccolorafus, R. 

 sJiiph'i/i, R. everfsi, R. simiis, Hyalomma scgyptium, and Amhlyomma hehrieum. Posi- 

 tive results were obtained only with R. shipleyi, commonly known as the brown 

 tick, and this tick was fomid to be pathogenic only in its adult stage. Detailed notes 

 are given on the habits and life history of the various species of ticks. In combating 

 infestation with ticks the author recommends burning over infested fields wherever 

 this method is possible, and the dipping and spraying of cattle with arsenical solu- 

 tions. Carbolic dips are not recommended. Kerosene oil ai:)plied in various ways 

 has given fairly satisfactory results. It is believed that 1 year is not too long a period 

 of (|uarantine for infested fields. 



Ringworm in cattle {Bd. Ayr. and Fisheries [London], Leajkt 95, j>p. 2). — Brief 

 notes on the cause and treatment of this disease. A number of preparations are 

 recommended for treating affected herds. Good results have l^een obtained from the 

 use of a preparation containing 5 parts train oil and 1 p^rt sulphur. 



Warbles or grubs in cattle hides, R. C. Jacobson {Proc. Nat. Live Stock Assoc, 

 6 {190S), pp. 202-204)- — The author calls attention to the injury produced in cattle 

 hides by the presence of the larvte of the ox warble fly. It is stated that ]>ackers 

 have agreed to classify cattle hides according to the number of warble holes in each 

 hide. Class No. 1 includes only those hides which have not more than 4 warble 

 holes. The author calls attention also to the irritation the presence of these grubs 

 produces and of the consequent loss of flesh. The treatment for these parasites is 

 conqiaratively simple and the author urges its prompt application. 



Inspection of sheep on the range {Proc. Nat. Wool Growers' Assoc, 38 {1903), 

 pp. 75-84). — This is a discussion by members of the association on the general subject 

 of inspection of sheep on the public range, with special reference to its bearings upon 

 the use of summer range, particularly in forest reserves. It was urged by some of 

 the members that the general inspection of sheep for scab might result in some limi- 

 tation of their privileges upon the public range. 



Sheep pox and the epitheliomata of this disease, F. J. Bosc ( Centbl. Bakt. n. 

 Par., 1. Aht., Oriy., 34 {1903), Nos. 5, pp. 413-420, Jigs. 2; 6, pp. 517-526, figs. 6; 7, 

 pp. 667-674, pl»- 3). — A detailed descrij^tion is given of the lesions observed in cases 

 of this disease in the skin, cornea, rumen, fourth stomach, lungs, liver, kidney, pan-
