Concluding observations on the Cetacea, pp. 194-204. 



The book closes with a fitting and diagnostic ''Appendix" devoted to "Testimonials, Cer- 

 tificates, Letters, etc., etc.," which, as the saying is, "should be seen to be appreciated." 



Besides numerous wood-cuts, there are plates of the flowing species, none of them origi- 

 nal, and most of them are even poor copies almost too poor to render the originals from 

 which they were taken recognizable in them : Balcena mysticetus, Balcena islandica, Balce- 

 noptera gibbar, pi. to face p. 15. Balcenoptera acuto-rostratus, pi. to face p. 97. Balcenoptera 

 jubartes and Balcenoptera rorqual, pi. to face p. 107. Skeleton of Balcenoptera rorqual, pi. to 

 face p. 115. Monodon monoceros (two figures), pi. to face p. 131. Physeter macrocephalus 

 and Physeter microps, pi. to face p. 148. Physeter cylindricus, pi. to face p. 161. Physeter 

 bidens sowerbyi, pi. to face p. 165. Physeter gibbosa, pi. to face p. 169. Delphinus didelphis 

 [sic] and Delphinus phoceana [sic], pi. to face p. 170. Skull and Skeleton of Porpoise (too 

 wretched for criticism), pi. to face p. 174. Delphinus orca communis, pi. to face p. 178. Del- 

 phinus gladiator and Delphinus tursio, pi. to face p. 184. Delphinus deductor and Delphinus 

 bidens, pi. to- face p. 185. Delphinapterus beluga, pi. to face p. 190. 



Prom the standpoint of systematic zoology, the present work merits little consideration ; 

 it contains, however, a modicum of information based on the author's own observations, 

 which in some degree redeems it from being merely an indiscriminate compilation, which is, 

 however, its general character. [811 ]
