added, and the preparation is spread in a tliick layer on strong paper. 

 (5) A " tanglefoot " mixture is made by warming together Venice 

 turpentine 1 part and American turpentine 4 parts and adding castor 

 oil 2 parts ; the mixture is spread on parchment paper. (6) Ten 

 parts of resin and five of sesame oil are melted together. (7) Pine 

 resin 25 parts, boiled linseed oil 18, yellow wax 2, castor oil 5, all by 

 weight. (8) Laurel oil is used to keep flies away from horses ; it does 

 not damage the skin and gives lustre to the coat. Asafoetida (vinegar 

 solution), walnut leaf decoction, and cresylic acid also act as deterrents. 

 A castor-oil plant kept in a flower pot will effect the same result, the 

 lower portion of the leaves exuding a viscous substance, poisonous 

 to flies.

 Sydney, xxv, pt. 2, Feb. 1914, p. 105. 



The author states that the red mites and lice which infect poultry 

 can only exist on these or allied birds, and there is no fear of their 

 transferring themselves from a fowl-house to any other building ; a 

 fowl-house would remain infested possibly from 2 to 4 months after 

 the removal of the birds, but after this the insects would die out.

It was shown by experiment that flies breeding in a mass of manure 

 about half a mile away from certain dwelhngs and 150 feet above 

 them, found their way into the houses. A small quantity of the 

 manure was placed in a pit and covered with a cage, the flies which 

 hatched from it being sprayed with an aqueous solution of gentian 

 violet to which a small amount of gum tragacanth was added. A 

 large number of flies were caught on fly-papers in the dwelhngs, the 

 marked ones being detected when treated with a solution of alcohol 

 and glycerine. A noticeable diminution in the number of flies infesting 

 the dwellings was observed when the manure was destroyed.

The author gives a brief account of the history of Texas fever and 

 of the experiments conducted for the Bureau of Animal Industry, 

 since 1889, by Smith, Kilbourne and Salmon. A list of synonyms of 

 the disease is given, the best name for which he considers to be tick 

 fever. The causative organism of the disease isPiroplosma bigemi- 

 num, which is transmitted by a tick, Boophilus (Margaropus) annulaius. 

 The death rate varies from 10 per cent, in chronic cases up to 90 per 

 cent, in acute cases. Eecent experiments with this disease have been 

 principally directed to obtaining a satisfactory chemical solution for
