BLOOD. 31 Taking this drop of blood from my finger as a standard of comparison, we find, on applying the mi- crometer, that the disks rim from l-2500th to l-5000th of an inch; but that the great majority are about l-3300th in diameter. On these slides are samples of other kinds. This is the blood of a Fish,—the common Blenny or Shanny {Blennius pholis). Here we see at once the oval form of the disks; their average is l-2800th by l-3300th of an inch. Here

Here we see at once the oval form of the disks; their average is l-2800th by l-3300th of an inch. Here is the blood of a Frog {Rana, temforario); these are more than twice the size of the fish's; for they average l-1250th by l-1800th of an inch. And, finally, I can show you a drop of blood from this Smooth-newt {Lissotriton punc- tatus). The large size of the disks is now conspicuous, and so indeed is the elegance of their form: in this case, as in the last, we see in each disk a distinct round- ish nucleus. These run from l-YOOth to l-950th in length, by 1-llOOth to l-1600th in breadth; but the average are about l-800th by l-1300th of an a Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Gosse, Philip Henry, 1810-1888.
