to where the animal became immersed, 1. e. the visible part of 
its back. The estimated measurements of the individual of captain 
M’QuuaeE (n°. 118) were: length of the head about three feet, 
breadth about two feet; diameter of neck below the head about 
one foot and a third; length of the neck to the fore-flappers about 
twenty feet; length of the trunk from the fore-flappers to the hind- 
flappers about twenty feet, length of the tail about forty feet, 
length of the whole animal between eighty and ninety feet. Let us now 
repeat those of the individual of the Osborne, which seems to be 
about three times larger. The breadth of the head is about six 
feet, consequently the length of the head about nine feet; the 
diameter of the neck below the head about four or five feet, say 
four feet, i.e. ¢hree times one foot and a third; the distance from 
the occiput to the flappers -— forty feet, according to my calculation 
given above but, — comparing the dimensions of the individual of 
Captain M’Quuae with the present, I don't hesitate a moment to 
put down sixty feet for the distance from the head to the fore- 
flappers. The officers of the Daedalus were in a more favourable 
situation to estimate this distance, the distance from the fore- 
flappers to the hind-flappers and the whole length of the animal 
they saw, — than Lieutenant Haynes; for the former saw the 
animal from aside, whilst the latter beheld it from behind, and 
was consequently in a bad situation to estimate the different 
lengths of the animal, but in a more favourable to estimate its 
different breadths. The length of the neck must really have been 
formidable, for though the animal (see drawing) showed hardly 
any neck at all, (resembling an enormous ball just visible above 
the surface of the water, with another smaller bullet on its top,) 
Lieutenant Haynes estimated the distance from the top of the 
head to the part of its back, where it became immersed, at fifty 
feet! The remaining part of the back and the animal’s tail and 
hind-flappers were entirely invisible. I have already expressed my 
firm conviction that the ridge of fins has nothing at all to do 
with the animal. It is evident that Lieutenant Haynes himself 
had his doubts about this point, for else he would not have 
written: “unless the ridge of fins....... were really the contin- 
uation of the shoulder to the end of the object’s body”. Evidently 
the animal elevated its head from time to time some feet into the 
air to take a survey before it. Evidently it never dropped its head 
so as to come with its nostrils below water, for “there was an 
entire absence of blowing or spouting’.
