give a total of somewhere about one hundred. Although parallel to 
each other and to the long diameter of the body, they were not in 
perfect straight lines, but adapted themselves to the curve of the 
throat and chest, being shortest as they ascended towards the back. 
They commenced a short distance from the mouth or lower lip, and 
did not extend quite so far back as the penis. 
The breadth of each of these folds varied from 2 to 5 inches, and 
their height was about an inch. The interspaces or furrows were 
one or more inches wide, according to the manner in which the part 
was stretched. Here and there these plications joined each other at 
acute angles.

3. Vertical section through four of the smaller ridges and grooves. 
A vertical section of the skin showed that the crown of each ridge 
had a thick cap of hard cuticle covering it, and which was of greatest 
depth at its centre, shelving off on either side (see fig. 1). The 
furrows themselves were lined with thinner soft cuticle, and, as best 
seen in the smaller grooves, they became widened at the bottom, 
where the skin was raised in several puckerings or folds. These 
last, as well as numerous wrinkles of the free edges of some of the 
ridges, no doubt admitted of the easy distention of the parts. The 
woodcuts (fig. 1 a and 4), drawn from nature, show these several 
points. Heddle has given a couple of linear diagrams to illustrate
