The wound was stitched up, any emphysema relieved by needle 

 puncture and healing took place by first intention. 



Volatile vermifuges that are exhaled by the lungs are especially 

 useful. Thus garlic, onions, asafoetida and even ginger in com- 

 bination with gentian in the food or water, destroy the embryos 

 in the alimentary canal and often also the mature worms in the 

 air-passages. Spirits of camphor or oil of turpentine, smeared on 

 the downy breast so as to be inhaled, operates well, and may be 

 introduced into the trachea on a feather. Tobacco, salicylic acid 

 solution, kerosene or benzine may also be used in the trachea. 

 Sulphurous acid or salicylic acid, or sodium salicylate (5:100) so- 

 lution may be introduced through the larynx, or the fumes of 

 burning sulphur may be inhaled largely diluted in air and with 

 extreme caution. Tobacco smoke may be blown under a cloth 

 covering the birds until they fall over inanimate, when the cloth 

 is removed and they revive in the open air. Other vermifuges 

 may be employed in a similar manner, special care being taken to 

 avoid asphyxia to which birds are so prone. 



PARASITES OF THE CIRCUI^ATORY SYSTEM. 



H^MATOZOA IN THE HORSE. 



The blood of the horse is the home of the Trypanosoma 

 Equiperdum of Dourine, the Tr. Evansi of Surra, the Tr. 

 Brucii of Nagana and the Tr. Equinum of the Mai de Caderas. 

 (see Vol. IV). 



Among nematodes the Sclerostoma Equinum is the most 

 common, forming aneurysms in the mesenteric arteries, coeliac 

 axis, renal and spermatic arteries and even invading the posterior 

 aorta, portal vein and other blood vessels (see Vol. II) ; the 

 Spiroptera Reticulata found in the arteries of the metacarpus 

 or metatarsus, and those on the side of the cervical ligaments ; 

 the Filaria Papillosa which is so common in the serosae (see 

 parasites of the intestines in the horse) ; and the Filaria Sangui- 

 nis Equi found by Sonsini in the blood of Egyptian solipeds. 

 The species of the last filaria is uncertain. As the same animal 

 had filaria papillosa in the peritoneum it is plausibly suggested that 

 these were the larvae of that worm, the more so that Wedl found
