phin, and in Griffith's Cuvier the same numbers are given ; 
Sir William Jardine says 12 dorsal and 52 lumbar. Of the cer- 
vical vertebrae, the first and second were large and scarcely 
movable upon each other; the other five were much smaller 
and rather more movable, the second being more, and the 
seventh less developed than in the D. delphis, accord- 
ing to Cuvier (Oss. Foss. v. 303) ; these vertebrae, he says, are 
fused into a single piece, and yet, he elsewhere says, (Anat. 
Comp. i. 105,) that in the dolphins the atlas and axis only are 
united, the other cervical vertebrze remaining separate, though 
extremely thin. Lesson (Cet. p. 226) describes the six first 
as quite thin in the D. delphis, and the last as some- 
what thick. These discrepancies, upon so important a point 
as the number and form of the vertebrae, can only be explained 
by the confounding of species, and, with regard to the present 
individual, its specific appellation must be left undetermined. 
The stomach, with the cesophagus, and part of the intestine, 
having been inflated, dried and varnished, showed the form, 
and, to a certain extent, the structure of the different cavities, 
better than if they had been laid open, and from this specimen 
a Very correct drawing was taken by Dr. Parker. (PI. XIV. 
fig. 2.) The esophagus is 5: inches in length, and about 7 
lines in diameter ; the first cavity of the stomach (a), which is 
perfectly identical with it in structure, dilates gradually, and is 
l; by 1 inch. The second cavity (b), continued in a line with 
e esophagus, is about 1: inches in length, and terminates in 
à blunt cone, so far corresponding with the general description 
by Mr. Hunter and others of the first; it differs, however, 
ruurely in structure from what is here described as the first, 
. 8 More red, thicker, and much more muscular; the two 
are also separated by a deep groove externally, and a corres- - 
Ponding fold of membrane within, though they still com- 
aiia freely, (portions of the cavities have been cut away 
80 as to show their interna] relations) ; it is equally remarkable, 
then, whether considered as an additional cavity, or as a mod- 
“aon of the first, which is so generally uniform in shape and
