posteriorly, a feature not shown in the older foetus which, as I have 
figured it, is almost straight on the upper surface. I believe this to 
be due merely to collapse of the soft spermaceti containing head. I 
have little doubt that the same state of affairs accounts for the shape 
of the head in the feetus examined by Kiikenthal which, being older, 
should be straight on the surface like my oldest fcetus. 
THe Trunk. 
We shall now proceed to consider and compare the trunk of the two 
feetus. ‘The following measurements apply to the two fetus described 
in the present paper. 
(1) Foetus of 44 inches. (2) Foetus of 94 inches. 
Tip of lower jaw to front edge of 
umbilicus (in a straight line) - 47 mm. 115 mm. 
Front edge of umbilicus to end of tail 57 mm. 123 mm. 
Front edge of umbilicus to anus = 22 mm. D4 mm. 
Anus to end of tail - = = 35 mm. 75 mm 
Tt will be noticed that the above measurements are not always 
exactly and collectively equal to the total measurements of the feetus 
given above. It is difficult to be exact; but it will be seen that 
there are no great discrepancies. These measurements bring out the
