KDITORS rKEFACH. IX 



the ])urchase of manuring matter, however valuable, 

 at the cost of all domestic comfort. The sewers must, 

 we fear, still receive what would be ofTensive to our 

 English senses. But can the contents of these sewers 

 not be made available ? The great mass of water which 

 necessarily accompanies at present the fertilising matters, 

 renders them of comparatively little value when com- 

 pared with the expense of transport. But how to 

 separate and concentrate these matters from the water 

 is a problem which is at present occupying the earnest 

 attention of scientific and practical men. The solutions 

 hitherto proposed are far from satisfactory. The future 

 of agriculture is, however, intimately connected with 

 the right solution of this great sewage question. 



In conclusion, I have only to state that the foreign 

 weights and measures have been, when necessary, trans- 

 lated into their equivalents in English, but have been 

 left unaltered when the point was only one of comparison, 

 which could be equally illustrated by the foreign weights.
