Donate of ammonia), and tonics (gentian, cinchona), must be 

 used to sustain the failing strength. 



CROUP OR ROUP IN FOWLS. 



Causes. — Probably similar to those acting on quadrupeds. 

 Exciting diet (wheat, buckwheat, oats), seems at times injurious. 

 Newly-arrived fowls are most liable to contract it, yet it does 

 not seem contagious in the ordinary sense, but rather inherent 

 in soil, locality, or conditions of life. 



Sy77iptoTns. — Dullness, sleepiness, neglect of food, ruffled 

 feathers, unsteady walk, quickened breathing, with a hoarse 

 wheeze, and an occasional loud crowing noise. On the tongue, 

 at the angle of union of the beak, or in the throat, appear 

 yellowish white films {false memiranes) firmly adherent to a 

 reddened surface, and raw sores where these have been de- 

 tached. The nostrils may be completely plugged with swelling 

 and discharge so that breath can only be drawn through the 

 open bill. The inflammation may extend along the windpipe 

 to the serial cavities and lungs, or along the gullet to the intes- 

 tines. In the first case death may take place from suffocation, 

 and in the second from diarrhoea, and as early as in twenty-four 

 hours. Toward the end of an outbreak, the malady may last 

 twenty days and still prove fatal. False membranes may form 

 on other distant parts of the body, but especially the comb, 

 wattles, eye, or on accidental sores. 



Treatment. — Disuse raw grain, and feed on vegetables and 

 puddings made of well-boiled oat, barley, or Indian meal. 

 Dissolve carbonate or sulphate of soda, or chlorate of potassa 

 •freely in the water drunk, remove the false membranes with a 

 feather or forceps, and apply to the surface with a feather the 

 nitrate of silver lotion advised for croup in quadrupeds. If 

 diarrhoea supervenes, give a teaspoonful of quinia wine thricb 

 a day. It is all-important to change the run of the chickens 

 for a time at least.
