VETERINARY SCIENCE AND PRACTICE. 411 



t-attlf are Slrougy'lns filarki, S. viicriirus, and S. contortus. The animals upon which 

 the author made his observations in Texas were also infested with Uncinar'ui radia 

 and (J^sophagostovia columhianum. These worms appeared to be so well protected 

 against vermicide treatment that quite unsatisfactory results w^ere obtained front the 

 use of turpentine, chloroform, carbolic acid, benzine, creosote, liquid sulphur, and 

 formalin. The post-mortem appearances of infested animals are briefly described. 

 In preventing the spread of the disease the author recommends isolation of affected 

 animals, drainage of pastures, and a pure water supply. 



Dipping- tanks, G. S. Armstrong {Agr. Jour, and Min. liec, (! {190S), Xu. 15, 

 pp. 566-568, jiy. i). ^Attention is called to the necessity of dipping cattle and to the 

 use of certain dipping vats and chemicals. The author describes the details of con- 

 struction of a dii)ping tank for cattle which has been found to give satisfaction in 

 operation. The cost of the dipping tank will vary, according to the materials used, 

 between $350 and $500. 



Dipping tanks, G. D. Alexander {Agr. Jour, and, Min. Rec, 6 {1903), No. 14, 

 pp. 519-o..'4). — A number of opinions were secured from various people who have 

 had experience in dipping cattle as to the effectiveness of this process. It was 

 found that cattle could be freed from ticks for a period of 3 or 4 weeks during the 

 worst season as the result of one dipping. The dip which was used most extensively 

 contained arsenic, soap, and Stockholm tar. 



The loco and some other poisonous plants in Montana, J. W. Blankinship 

 {Montana Sta. Bid. 45, pp. 75-104, figs. 7). — The conditions under which plant poison- 

 ing occurs in Montana are briefly outlined. The distribution of the loco plant is 

 briefly described and notes are given on its symptoms. In combating this trouble it 

 is recommended that lambs be prevented from grazing on loco areas until late in the 

 season, when the plant becomes less palatable. 



W. A. Tudor made an experiment in the extermination of loco. He employed 2 

 men for a period of about 1 month, during which they succeeded in digging up the 

 loco plants on an area of 16 square miles. The plants were cut off just below the 

 crown by means of a heavy hoe. Where this was properly done the loco plants did 

 not sprout again and have not appeared during the present season. 



Descriptive and biological notes are also given on lupine, water hemlock, death 

 camas, larkspur, and wild parsnip {Pteryxia (hapsoides). All of these plants are 

 believed to cause greater or less loss of stock in Montana. Brief notes are also given 

 on the effect of alkali upon stock. The author presents an analytical synopsis of 

 symptoms for the determination of the cause of poisoning. A brief bibliography of 

 I)oisonous plants is appended. 



Plants injurious to stock, T. N. Willing {Rpt. JJept. Agr. Xortlurest Territories, 

 1902, pp. 33-44, figs. 9). — A number of plants have been found to ])e poisonous or 

 have l)een suspected of causing the death of domesticated animals in the Northwest 

 Territories. Notes are given on some of the more important species, including horse- 

 tail, larkspur, corn cockle, lupines, loc» weeds, water hemlock, death camas, etc. 

 The symptoms produced by eating these plants are briefly described. 



Hog cholera, C. L. Willoughbv [Georgia Sta. Press Bid. 41, pp. 4). — Notes are 

 given (jn the nature, cause, means of distribution, symptoms, and treatment of this 

 disease. Suggestions are also made regarding sanitary measures, disinfection, disposal 

 of dead animals, preventive regulations, and the control of the disease by State laws. 



Hog cholera, D. Hutcheon {Agr. Jour. Cape Good Hope, 23 {1903), No. 2, pp. 

 134-137) . — Brief notes on the symptoms and post-mortem appearances observed in 

 this disease. 



Hog- cholera, W. C. Quinnell {Queensland Agr. Jour., 13 {1903), No. 2, p. 92, 

 ph. 2) . — Notes on the symptoms and etiology of this disease, which is shown to be 

 distil ct from swine plague and swine erysipelas.
