Comparison of the dimensions. Supposing that the dimensions of 
the several portions of the animal are relatively nearly the same 
in individuals of different ages, we are able to draw up a table 
of comparative and relative dimensions. We learn from the officers 
of the Daedalus that the vertical diameter of the neck was about 
1*/, feet. From the officers of the Osborne we have the following 
estimations of dimensions: horizontal diameter of the head about 
6 feet, horizontal diameter of the neck about 4 feet. We know 
from several eye-witnesses that the neck is round, so that we may 
suppose that its vertical diameter is the same as its horizontal or 
transversal one. Consequently the transversal diameter of the neck 
of the Daedalus animal was 1?/, or 4/, feet; and that of its head 
°], = 2 feet. For a moment I will suppose that in these animals 
a head of about 2 feet broad has a length of about 3 feet, and 
this I may do, as the heads of the animals which I consider as 
allied to sea-serpents, have nearly these relative dimensions. In 
the same way I may put the length of the head of the Osdorne 
individual at about 9 feet. The distance from the head to the 
foreflapper in the Daedalus animal was about twenty feet. We may 
consequently suppose that the same portion measured sixty feet in 
the individual seen by the officers of the Osborne. As to the ques- 
tion whether this portion is to be called the neck as I have done 
hitherto? I answer without hesitation zo, this length also includes 
a portion of the animal’s trunk, viz. the part from its shoulder 
to the point where the fore limb is free. In the animals which, in 
my opinion, are allied to the sea-serpent, the upper arm is, so to 
say, “imbedded” in the trunk’s integument, is not free, as in 
man, and nearly immovable, and this portion is about one third | 
of the whole length of the limb. Consequently we may conclude 
that, if the free part of the foreflapper is about fifteen feet, the 
portion of the trunk from the place where the fore limb in seated 
on the body to the shoulder is about seven feet and a half. Con- 
sequently the individual of the Osédorme had a neck of about 
53 feet. As the size of the individual of the Daedalus was 
about one third of that of the Osdorne, its neck was about 
17*), feet long. For the same reason the foreflappers of the Dae- 
dalus individual were five feet in length. The distance from the 
foreflapper to the hind flapper in the Daedalus animal measured 
about 20 feet, consequently the érun& measured 22'/, feet, so that 
the distance from the foreflapper to the hindflapper of the Osdorne
