With regard to "Lung-worm" — cnvfinued. 



Tn all cases the woriiis were alive and vigorous. 



One sheep from each lot was weighed at the c(tmjnenceruentof the experi- 

 ment, at ten days and at twenty days. 



Results were as follows : — ■ 



So far, therefore, as these experiments go, the best all-round results were 

 obtained from giving the sheep a liberal diet and a full allowance of salt. 

 No one who had seen the sheep at the beginning of the experiment, and 

 noted how tliey stood out above the others in general appearance at the end 

 of the twenty days, could help admitting that intra-tracheal injections gave 

 favourable results in regard to destroying the parasites, and the weighed 

 sheep gained considerably, but this method cannot be taken into consideration 

 for large flocks. Results from fumigation were somewhat disappointing, as 

 in no case were all the worms got rid of. All the drenches failed equally to 

 procure the expulsion of the parasites, and it is very doubtful whether any 

 drench will prove successful, while the weighed sheep did not gain to nearly 

 the same extent as those treated in other ways. (J wing to the lateness of 

 the season the positive results cannot be regarded as absolutely final, but this, 

 of course, has no bearing on the failure of any of the methods of treatment. 



As these sheep were also badly infested with stomach and intestinal 

 worms — Strongylus contortus in the fourth stomach, Trichocephalus ajfinis in 

 the csecum, and (Esophagostoma cohimbimtum in the caecum and large 

 colon — these experiments provided an opportunity of noting the effect of the 

 various drenches on these parasites.
