period and of 1.4 lb. per pig per week on the average of the second experi- 

 mental period or an average gain for the whole period of 1.35 lb. weekly. 

 On the other hand the use of fish meal to the extent of one eighth of the 

 total ration as a substitute for an equal weight of sha^DS increased the 

 cost of feeding by barely 1/2 d per pig per week. If, further, the residual 

 manurial values be allowed on the scale suggested by Hall and Voel.cker, 

 the fish meal becomes actually cheaper since the manurial value of the 

 fish meal is £ 4 8s per ton, whilst that of the sharps is but £ i qs per ton. 

 But even leaving out of account the manurial value and considering only 

 the live weight gains, there can be no doubt as to the decided benefit of 

 partially replacing sharps by fish meal. 



No objectional taint was imparted to the carcass of the animal by 

 the use of fish meal.
