Phocama, or the Anatomy of a forpefs » 4| 
There remains the Ofieology, or to give an account of 
the Bones and Sceleton of this fifh, and in general I fhall 
oblerve of them, that as the Mulcles and molt of the Vifct- 
ra very much imitated the ftrufture of thole of Quadru- 
peds, lb likewile the Bones here came very near them, as 
to their folidity, colour and ftrufture, and in all excepting 
what differences the neceflity of the figure of this filh 
occafioned. I fhall begin with thole of the Head, where 
I fhall take notice of the Cranium, the Rofirum and lower 
Jaw or Maxilla. For where (a») Rondeletim faith, a 
Phocana has no Rofirum , it mu ft be underftood of its ap- 
pearing fo whil’ft the flefh and fat is on ; whole great 
bulk does render it obtule and curt : but when his ta- 
ken off it appears otherwile ; for then the upper Jaw or 
Rofirum from the Cranium to its Extremity is fix inches 
long, but in a Dolphin much longer* At the beginning 
* Tab. 2. of this bone juft below the Cranium is the Fifiula or * Na ~ 
Fig. x . aa. res ^ w hich as is related before was divided by an offeous 
fief turn into two Cavities. The fifiula was formed part- 
ly by that bone Columbus calls the Vomer , which arifing 
from the Palate does lend a thin Lamina up the Cranium , 
and is continued on the os frontis to the great Protube- 
t b. ranee in the middle there, forming three f protuberances 
on the os frontis above the fifiula. The other part of the 
fifiula is formed by two bones, pretty large at their balls 
and rifing above the furfaceof the Rofirum , and lending 
II ce. down two I! Pyramidal procefles about two inches long, 
between the inward bones of the Rofirum. For the Ro- 
* d- ftrum was compoled of four Bones, the two * outward- 
moft were a continuation of thole of the Cranium ha- 
ving two procelfes, the firft that compoled part of the 
Ilf II ps Zygomaticum^ and another about two inches lower ; 
then it grew narrower, not being almoft half the breadth 
as it was before. To be too nice and (crapulous in the 
delcription of all the bones here might leem tedious and
