Or those cf the above .sheep which were drenched, only two out of ten 

 .showed many stomach and intestinal worms on "post inortem^ but of those 

 undrenched ten out of fifteen showed bad infestation, usually with at least 

 two out of the three forms of stomach and intestinal parasites found. 



There would, therefore, appear but little doubt that the drenches used 

 caused some improvement in the stomach and intestinal infestation, but 

 were unable to destroy all the worms present. The sheep treated with the 

 departmental drench showed very good results, but unfortunately^ only one 

 -post mortem could be made. 



In no case was there any evidence that any of the drenches used caused 

 the slightest harm to the sheep ; in fact, all the weighed s^lieep under treat- 

 ment gained to some extent. 



In conclusion, the results obtained would seem to emphasise again the tact 

 that the giving of good feed and salt is the best treatment to apply to sheep 

 affected with worm infestation of any description ; that while stomach and 

 intestinal worms can be dislodged fairly readily, bronchial ])arasites can be so 

 only with great difficulty ; and that stock-owners must look to preventive 

 methods rather than to " cures " to save themselves from loss from this cause.
