 [Received 28th January 1918.] 



The method of destroying sheep-maggot flies by trapping them before 

 they have time to deposit their eggs upon the sheep is one that is 

 yielding good results. A cheap and simple trap can be made by 

 covering the open end of an empty kerosene tin with wire gauze which 

 must overlap the sides about 2 inches. Let into the centre of this 

 cover is a funnel, 4 inches in diameter and 5 inches long, the opening 

 at the apex, inside the tin, being about the size of a threepenny piece. 

 The inside of the tin is painted white, the outside also being painted 

 as a protection. The trap can be baited with any offal or with sour 

 milk.

Vermin in poultry houses naturally fall into two groups, parasites 

 that live and hibernate in the j30ultry house on roofs, etc., such as 

 Dermanyssus gallinae (red mite), and those which pass their whole 

 existence on the fowl, such as Goniocotes abdominalis (large chicken 

 louse). The latter may be combated with a dust bath, or by dusting 

 the birds by hand with insecticides, or sulphur, or wdth equal parts of 

 sulphur and fine ashes. The best method of keeping poultry houses 

 free from vermin is to spray them with kerosene emulsion as often as 

 necessary. The emulsion, which should be applied by a force pump so 

 as to reach all the cracks and crevices, is composed of 8 oz. soft soap 

 dissolved in 1 gal. boihng water, 1 gal. of kerosene being slowly added 

 while stirring, and the whole thoroughly shaken to effect emulsification. 

 For use, 10 gals, soft water must be added, and if the spray is to be also 

 a disinfectant, one tablespoonful of miscible carbolic acid to each 

 gallon of emulsion should be stirred in. Where the infestation is 

 severe, 2 or 3 applications may be necessary at intervals of 1 or 2 days.

This paper is a review of the subject of tick-infestation, and gives an 

 account of the various parasites transmitted by Ixodids and of their 

 ■evolution in the tick and in the animal host. The method of trans- 

 mission from tick to host is described. The ticks dealt with include 

 Margaropus annulatus, which transmits Piroplasma bigeminum and
