article of food. On the other hand, the wels recom- 

 mends itself for acclimatisation in more than one 

 respect. It may be procured in large numbers from 

 the numerous lakes in Mecklenburg and Northern 

 Prussia, at the place indicated in the beginning of 

 this paper ; the price of 1000 young fish would not 

 exceed 15. Its tenacity of life insures an easy trans- 

 port during the two or three days' journey, without 

 any considerable loss, if young examples, not above 10 

 inches in length, be selected, and the transport be 

 made during the cooler part of the year. The place 

 for its reception must be judiciously chosen, but 

 there are numerous lakes in the north of England, 

 Wales, Scotland, and Ireland, whose physical features 

 are in accordance with those of its native place ; and 

 we sincerely hope that the few specimens which are 

 now in possession of the Society of Acclimatisation 

 may be the forerunners of a more extensive immigra- 

 tion, which might draw yet another presumption in 

 favour of success from the fact that all the immigra- 

 tions of animals which are known to have taken 

 place in a state of nature have proceeded from east 

 to west.
