Moderate-sized specimens of tins species should be pre- 

 served entire ; and the head, vertebraj, with the dorsal 

 spines, Tiscera, and especially the impreg-u-^3d oviduct, 

 should be placed in spirit or solution. The Southern

 of this fish, and the ova and young in different grades 

 of development, preserved in spirits or the solution 

 No. I., are much wanted, in order to complete its ana- 

 tomical and physiological history. 



With regard to most fishes preserved in spirit or sol 

 tion it is desirable to inject some of the preserving liquor 

 into the alimentary canal, and, if the fish be large, to 



make a small opening into the Ijeliy. The more delicate 



u 



specimens should be sewed or wrapped in rmen, m order 



to preserve the scales. 



For dry specimens the larger kinds ma; ')e skinned, 

 and the skin should be washed on the inner side with the 

 arsenical soap, and then loosely filled with cotton, wool, 



or tow. With regard to the smaller or moderate-sized 

 specimens, the Curator of the Dublin University Museum 

 states : — " An excellent mode of preserving fishes, easily 



accomplished, may be thus described : Lay the fish on a 

 table, with the side up which you wish to preserve, then 

 with scissors cut it, so as to separate the fins, skin of one 

 side, mouth, and tail, from the body and viscera ; spread 

 the skin so obt^imed on a linen cloth, fold it over it, and
