 I ii.w E the honor herewith to sultmit mv report on tlie experiments recently 

 carried out at (jllen Times on " Lung-worm in Sheep ' 



These experiments were commenced on IDth September, 1908, at the Experi- 

 ment Earm, Glen Tnnes, when forty-thrt-e sheep, got together by Mr. Gennys, 

 the Manager', as being aliened with "lung worm," were in one way or another, 

 brought within the scope of the experiment. Tlie sheep were mixed merinos 

 and cross-breds, forty-tivo about 11 mouths and oneahout two years old, the 

 property of the Experiment Farm and of Mr. L)a\idson, a neighbouring 

 farmer, who very kindly provided them fni- experimental ])urposes. All tl)e 

 sheep were in poor condition, many with a constant cough, and some showing- 

 marked cedema between the lower jaws. Jn order to discovei' the extent of 

 the infestation, three were killed, with the following icsults: —Sheep No. 1 : 

 11-month ni' rino ; verv jioor, with marked (edema Ix-twcen tlie ja^s. On 

 post mortem e.xannnation tliere was found considerable al)doniiiiid fluid, the 

 lungs were slightly mottled, no nodules, :(nd on section the bronchi and 

 bronchioles were found to be l)a(lly infested with str(mg\ les ; the rumen, 

 reticulum, and omasum were normal, hut a cnnsi(l(>rable numlier of strongyles 

 (stomach worms) \vere found in the abomasum, the cacuni also containing 

 large nund)ersof tliin white worms, otherwise the intestines appeareil noinial. 

 The li\ci' and spleen were normal, Itut the ki(hieys on section wei'e pale, 

 especially the medulla. On examination, the strongyles proved to be in the 

 bronchi and smaller air-passages, strongy/us flnria: in the 4tli stomacli, 

 stronyylus corUortus, wdiile the worms in the ca'cum were tlie tnchocephalus 

 affinis. 



Sheep No. 2, — 11 months, ci'ossd)red ; in fair coniiition, and without 

 oedema. The post mortem appearances were as in No. 1, save that no other 

 parasite was found liesides the d. filaria in the lungs, and tlie kiilneys wei'e 

 normal. 



Sheep No. 3. — 2 years old : similar to No. 2, but the lung infestation was 

 very bad, and many worm nodules were found in the mucous membrane of
