150 PHEASANTH FOR ('nVERTH AND A VI ARIES. 



enteritis caused Ijy intestinal worms is that set up by small 

 round worms wliich are fouud cliietly in tlie blind cieca of the 

 intestinal tract. These worms may bo so small as to require 

 ,1 microscope to iind them, or may be easilv visible to the 

 naked eye ; the one that is most common!)' associatecl with the 

 disease is known as Setfrnkis papilhiNa or H. iwsiciiJd ri^. 

 When it is present the liniufy membrane <:)f the intestine is 

 touud to be intensely inflamed, and in seyere cases the 

 intestine contains nothino' but blood-stained mucus. Tlie 

 symptoms are those of enteritis, namely, loss of apjjetite, 

 emaciation, diarrluea, &c., but death does not occur so 

 ra];iidlv as in enteritis cause<l by coccidia. The diseases 

 causeif l)y these parasites are infectious, as the eu'u's of the 

 worms are passed with the dropping's, and may be ]iicked up 

 by healtliy birds witli their foo<l. The treatment here miisr 

 he mainly preveutiye, moying the liirds oii to fresh ground, 

 and paying great attention to the purity of the water supply. 

 As a medicine santonin has been found very efhcacious, the 

 dose being four grammes to ten fiirds, given with the fo()d ; 

 male fern has also been o-iveii with advanta,<'-e. 



I'heasa.nts hatched under farmyanl hens are not ni- 

 fre(|uently liable to what are known as scurfy legs. This 

 objectionable disorder depends on the presence of minute 

 |jara,sites {Scirrupfrs nuituii^:) which live uiuh'r the scales of the 

 logs and upper part of the toes, where they set up an irritati<iii, 

 causing the formation of a white, powdery matter, that I'aises 

 the scales a,nd forms rough crusts, which sometimes lieconie 

 very large. When these crusts are broken off and examined 

 with a microscoiH', or e^"en ,1, good hand lens, tht'y will lie 

 found to be filled with the female parasites, generally distended 

 with eggs. 'J'he crust itself ma^y be com])ared to the crumb 

 of dry bread ; but the parasites are to lie found only in those 

 parts which are kept moist )jy the skin. They appear to 

 cause great irritation to the bird. 



This disease is ])ropagated by infection. It is seen in 

 ianciers' yards where the poultry are closely coullned together,
