Second Method. If no spirit of any kind can be pro- 

 cured, the fish may be preserved for a short period by 

 first soaking them for a day or two in strong brine (salt 

 and water), making a slit as before, and afterwards placing 

 them, entirely covered and surrounded by salt, in a box or 

 other receptacle. This may sometimes prove a convenience 

 to sportsmen, as fish thus temporarily preserved are less 

 easily destroyed in conveyance, or when travelling, than 

 if preserved in fluid. 



[It is earnestly hoped that in the event of any peculiar 

 specimens of Trout, Charr, or other fish being met with, 

 anglers will preserve them as suggested, and forward them 

 for inspection, either to the Curator of the Ichthyological 

 Gallery of the British Museum, or to some other com- 

 petent naturalist for his examination and report. 



Dr. Giinther of the British Museum informs me that he 

 is about to make a collection of the Trout (Salmo fario) 

 of the British Islands, with a view to determining whether 

 there are not, in fact, several distinct species at present in- 

 cluded under this name ; and he will, I am sure, be much 

 obliged by any assistance which Anglers may give him in 

 the task. In fact, it is only through the cooperation of 

 fishermen that a comprehensive collection of these nume- 

 rous fish can ever be practically made.]

To preserve heads of Fish. Take out the eyes ; place a 

 piece of stick between the jaws to keep them wide open ; 

 wash the head thoroughly over with a solution of corrosive 

 sublimate (four grains to the ounce of water), and hang it 

 up, under cover, where it can swing in the wind ; wash it 

 a few times with the solution at intervals of two or three 

 days ; and when it is quite hard and dry, varnish it with 

 shellac or copal varnish, inserting glass eyes in the sockets. 

 If a difficulty is found in drying, place the head for a day 

 or two in the kitchen fender.
