30 These measurements were taken from the eye before it was put in alcohol. it was carefully compared with the eye of a finback taken the next day. The eyeball is much more electrical than is that of the Finback. Very high (photographed). By peeling off portions of the epidermis I found the color to be gray slate, with little of any blue in it. This is probably the true life color of the back & head also. The Finback dorsal was neutral tint, with a good deal of blue? mixed with black & white, would get it. It was decidedly purplish which is probably life color & is what I have described the Alaska Finbacks to be.
