Buchanan. — On Pseudo-scab and Lung-worm in Sheep. 273 



but I fear the sheep were too far gone for any remedy to have effect. In 

 each of these latter cases I found on opening the sheep that the worms 

 had penetrated the lungs, and when this has occurred I am afraid there is 

 no cure. I have made the infected sheep inhale sulphur four times, at 

 intervals of three days, and the flock seem now quite recovered, in good 

 heart and feeding well. The sulphur inhalation is the cheapest and speed- 

 iest cure, and I am much indebted to you for your suggestion of it; in future 

 I intend putting the sheep through a course of this treatment at the end of 

 each autumn as a preventative, as I have noticed that this is the season 

 when the disease always shows itself first." 



Mr. Eeginald Foster, writing to the Stock Department, says: — "We 

 must look rather to preventive means. In this, as in the case of most 

 diseases, I think there must be some predisposition to contract disease, and 

 this is most likely to occur soon after weaning, when those lambs which had 

 not weaned themselves, being suddenly deprived of their natural food, are 

 for a time debilitated, and would therefore be the more susceptible to disease. 



" Most stock-owners wean their lambs on their best feed, which in 

 summer is usually on the moist low-lying land, where these parasites, or 

 rather their ova, exist. None but adult stock which are able to resist the 

 attacks of the bronchial worms should be put on rich swampy pastures. 

 Lambing paddocks should if possible be virgin pasture, or should have been 

 saved some time for the purpose, and the lambs should always have access 

 to rock-salt, which is the best known preventative for worms of all kinds. 

 The simplest remedies recommended are a dessert-spoonful of turpentine 

 to two of linseed oil, given every other day, about three or four doses ; or 

 the sheep should be placed in a close shed and made to inhale the fumes of 

 sulphur. This may be done by sprinkUng sulphur on a pan of live coals. 



" These remedies have been tried in two or three instances here, but I 

 have not yet heard with what result. I think they would only be effectual 

 in the very earliest stages."

" We have no knowledge of the cause of the lung- worm — a name given 

 for the want of a better perhaps. It affects young sheep in a greater degree 

 and to a greater extent than matured animals. The worm is a small white 

 one, and is found in considerable numbers in the lungs, or in tubes con- 

 necting the windpipe with the lungs. The symptoms are weakness, failure 

 to eat, loss of flesh, and a cough. This disease is but little understood by 

 the wool-grower. 



" Stricana or Strichnia is perhaps a very incorrect name for the disease 

 I wish to describe. It is caused by a very small worm, so minute, indeed, 

 that it cannot be seen without the aid of a magnifying-glass. It is believed
