Buchanan. — On Pseudo-scab and Lung-worm, in Sheep. • 271 



Preventative measures with this disease should always be tried in pre- 

 ference to what may be termed a cure, for it is only when the worms are 

 leaving instinctively that any cure is ever tried, and it were better to 

 assist their escape by cleaning out the nostrils of the sheep than killing 

 them in the air passages of the lungs with the fumes of burning sulphur. 



Either prevention of access of the worm to the sheep in spring, by their 

 removal to dry ground — or keeping rock-salt in places where the sheep can 

 have access to it, more especially when the young nematode has newly 

 reached the lungs and is of a microscopic size — should be adopted. 



When the young worm finds a nidus on the back, and the wool shows the 

 first symptoms of raggedness, an application of a mixture of soft soap in 

 water with a little turpentine or kerosene, if distributed in the opened wool 

 with a groove-corked bottle, would speedily check the evil. 



Extracts from Reports of Sheep Inspectors and Notes thereon. 



Mr. Foster in a report to the Stock Department describes very correctly 

 the disease in sheep caused by worms in the lungs ; but the proper time for 

 administering remedies is not stated, and any treatment which would kill 

 the worms after they have reached an advanced stage of development is 

 more likely to kill the sheep ; every means should be used to get the worms 

 out of the nostrils and prevent suffocation of the sheep. It is very pro- 

 bable that sulphur fumes might prove beneficial if applied when the worms 

 are of a microscopic size on their earliest arrival from the wet ground. 



Mr. Boyes seems to be on the right track with the sulphur fumes, he 

 says he is sure it will cure the bronchial disease " in its earlier stage," and 

 he means to use it as a preventative ; perhaps he expects too much in that, 

 as sulphur fumes are not likely to do much damage to worms before their 

 arrival. Why not put soluble sulphur in the blood through the stomach ? 



Mr. Eeginald Foster pomts out the main feature of the whole subject : 



"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. Lambing paddocks should be virgin pasture." 



Sheep Inspector Simpson, Marton District, reports as follows : " I for- 

 ward by mail to-day a package containing portion of a sheep's lung showing 

 a number of worms in its tubes, perhaps you may be able to obtain reliable 

 information if this is the cause of the heavy losses, chiefly in hoggets, for 

 several years past. 



" The first symptom is a severe cough, afterwards followed by scouring, 

 which invariably terminates in death. I have very little doubt but the 

 worm is the cause of the cough, and the scouring is an after con- 

 sequence."
