With regard to birds it in;tr be observed, that if spirit be injected 

 down the windpipe, it will pass through almost the whole body by 

 means of the air-cells. In the c ase of a quadruped preserved in spirit, 

 or in the Baline solution, it is proper to inject the preserving liquor 

 into the abdominal cavity and intestinal canal.

Supplement to the History of British Fishes. By William Yarrell, 

 F.L.S., V.P.Z.S., Illustrated by Wood-cuts. London, Van Voorst, 

 8vo. 1839. 



In an early number of the ' Magazine of Zoology and Botany,' 

 we noticed the work to which that bearing the title above is a Sup- 

 plement, considering it as one well executed in all its departments, and 

 of much importance in bringing together our knowledge of a branch 

 of the British Fauna which had not been investigated so minutely 

 as either the zoology or ornithology ; and moreover we looked upon 

 it as a work which was sure to cause the production of much ad- 

 ditional information. In the latter prophecy the Supplement before 

 us bears ample testimony that we have not been deceived, while it 

 also exhibits the zeal of the author in his interesting department, 

 and the assiduity with which he is assisted, which is mainly to be 

 attributed to the excitement given to our ichthyologists by the in- 

 terest of his previous volumes. 



The execution of the Supplement more than equals that of the 

 former volumes. Thirty-one figures of fishes are given, besides vig- 

 nettes illustrating structure or characters. Among the species the 

 greater number are new to our Fauna, the others being improved re- 

 presentations of fishes previously illustrated, or taken from speci- 

 mens where the former wood- cuts were, for want of better materials, 

 copied from drawings or other engravings. In the letter-press se- 

 veral mistakes and inadvertencies have been corrected. We trust 

 that Mr. Yarrell will continue to collect materials as he has already 

 done, and we will venture to predict that it will not be long before 

 they will again swell to an extent even beyond that which he has 

 already presented to the public. 



The following may be noticed as occurring among the more im- 

 portant corrections and additions to this Supplement : — Couch's 

 Serranus Mr. Yarrell has found to be identical with the Poly prion 

 cernuum of Cuv. and Val. An improved figure of the baagmaer or 

 Deal fish is given from the representation of Professor Reinhart of
