most successful remedy he has tried, sprayed into a box so 

 that the birds inhale it. 



Both Megnin and Montagu advocate the administration 

 of garlic with the food. Montagu gave an infusion of rue and 

 garlic instead of water to drink. Megnin gave chopped garlic 

 with the soft food in the proportion of one clove of garlic to 

 every six pheasants ; he also was fortunate in the employment 

 of powdered assafoetida given with an equal part of powdered 

 gentian, incorporated in a cake and given in the proportion of 

 .50 grammes per head per day. After the birds have been 

 removed from the field on which an outbreak of gapes has 

 occurred, the ground should be disinfected with lime and 

 ploughed up ; Theobald recommends watering the ground 

 with a 1 per cent, solution of sulphuric acid ; the ground 

 should not be used as a rearing ground the following year, and 

 all the coops should be fumigated and disinfected with lysol. 



It should be remembered that when exposed to dry heat 

 the eggs and embryos of Syngamus soon dry up and become 

 withered, and this explains why on dry soils and in hot dry 

 summers the ravages produced by the gape worm are not 

 so severe as they are on moist soils and in wet seasons. 



Favus. 



Another parasitical disease which attacks poultry and has 

 also been known to attack pheasants and other game birds is 

 favus ; this is an infectious disease of the skin caused by a 

 special fungus Lophophyton gallinae (Megnin), Tricophyton 

 megnini (R. Blanchard). The disease generally commences on 

 the comb, or wattles, but it may spread to the skin, especially 

 of the neck and body, and more especially the cloaca and 

 adjoining part (Neumann). It appears first on the comb or 

 wattles in the form of small white or light-grey spots that 

 extend, multiply, and become confluent, forming crusts 

 covering the skin ; these crusts gradually become thicker, 

 sometimes irregular in shape, often concentric. When this 

 covering is removed the skin beneath is seen to be excoriated.
