DISEASES OF THE OX AND SHEEP. 423 



diarrhoea. Lambs, however, are also troubled with scouring at 

 the same time. 



Two other varieties of strongylus, viz. the Strongyliis Jilaria 

 and the Strongyliis rufescens are also at times found present in 

 the lungs of sheep. The first of these, the Strongyliis Jilaria, 

 has its head provided with papillse, the mouth circular, and the 

 skin covered with warty papillae. Tne Strongylus rufescens has 

 its head unarmed. The mouth is furnished with lips, and the 

 oesophagus is short. The eggs are but few in number. The 

 males are about five or six inches long, the females about six or 

 seven inches. These strongyles are generally found together 

 with numbers of the Strongylus jilaria. Only a few of them 

 have ever been found in one sheep, and they are seen to be 

 coiled up in the substance of the lung. In order to prevent 

 husk, salt should be strewed all over the pastures, in order that 

 the larvfiB may be killed. 



As a curative medicine, the following mixture may be made : — • 

 Pulv. Scillse, 5 gr. ; Pulv. Ipecac, 1 dr. ; Besinse Ammoniaci, 

 \\ dr. This powder may be administered twice daily, or the 

 following mixture may be tried : — Tincturse Benzoini, 2 fluid 

 dr. ; Balsam of Peru, ^ fluid dr. Mix the two with mucilage. 

 Turpentine has also been recommended. 



We may here state that two authorities, Mr. Youatt and Mr. 

 Mayer, recommended by way of treatment of this malady the 

 daily administration of two ounces of salt at one part of the 

 day, and that of about seven fluid ounces of lime-water at some 

 other time during the same day. 



Acute injlammation of the lungs may be brought on in sheep 

 by the influence of cold and wet, as a result of chills after hard 

 driving, of careless or injudicious washing of sheep before 

 shearing, of shearing during tempestuous or inclement weather, 

 and other causes of a like nature. At the outset, the patient 

 exhibits febrile symptoms, has a quick and hard pulse (which 

 may become oppressed and intermittent), manifests a dislike for 

 food, ceases to chew the cud, is unwilling to move, heaves 

 slightly in the flanks, frequently gives utterance to a cough 

 (which is very distressing, and which, as the disease progresses, 

 becomes still more quick and painful), breathes irregularly, 

 completely loses all appetite, discharges an offensive and fetid 

 matter from the nostrils, grinds the teeth, is exceedingly thirsty.
