CIRCULATORY AND LYMPHATIC SYSTEMS 299 



the heart going at a great pace, whilst it can, in many cases, be heard 

 beating loudly at a distance of 5 or 6 feet from the side of the patient. 

 In milkers the secretion is suspended, the nose, eyes, mouth, udder, 

 and vagina have a dirty yellow cast, while the lips of the vulva have 

 a tight, puckered-up appearance, and the urine has, as already stated, 

 its characteristic red colour. The animal will take neither food nor 

 water, and in the first stages is affected with diarrhoea. As the 

 disease advances, all the symptoms become aggravated, but an 

 obstinate constipation takes the place of the diarrhoea. In my 

 opinion, this suspension of the action of the stomach and bowels is 

 due to the deteriorated blood acting on the nerve centres, causing 

 perverted action, or, in a degree, paralysis of the nerve fibres supply- 

 ing the alimentary tract, and the poor brute's condition becomes 

 much more aggravated by the owner, on seeing this symptom, pour- 

 ing into it large doses of relaxing purgatives, which only hurry it on 

 to dissolution. 



470. Treatment. — The treatment I recommend as soon as the 

 animal is observed to be affected is to give it from 14 to 20 ounces 

 of common salt in 2 quarts of gruel, and then to place in front of the 

 patient a large pailful of hay, nettle, or bran tea, or cold water and 

 milk in which from 2 to 3 ounces of hyposulphite or bicarbonate of 

 soda is dissolved. This must be renewed as soon as the patient 

 drinks it. It should be followed by 20-ounce doses of linseed oil, to 

 which is added 2 ounces of turpentine. Should the bowels not 

 respond, 4-ounce doses of hyposulphite of soda may be given along 

 with warm cordials, such as 1 ounce each of ginger, gentian, sweet 

 pepper, mustard, etc., in 2 quarts of warmed ale, or in gruel contain- 

 ing \ pint of whisky, every six or eight hours. I have found this 

 treatment to be very beneficial. A subcutaneous or intravenous 

 injection of a preparation of trypanblue is now supposed to not only 

 destroy the parasites in the blood, but also to render the animal 

 immune. 



471. Prevention consists in first draining the land, and then dress- 

 ing the particular grazing pastures affected every fourth or fifth year, 

 with 10 cwt. of rough, crushed rock-salt to the acre, while large
