and increaſes by the protruſion of globuls. But two or three days agoe I obſerved the Hair of an Elk, and found it wholly to conſiſt out of conjoyned globuls, which by my Microſcope appear'd ſo manifeſtly to mee, as if they could be handled. And therefore having ſo clearly ſeen thoſe globuls, I aſſure my ſelf, that the growth and increment of Hair is made (as I ſaid juſt now) by the protrusion and driving on of globuls. This hair of the Elk I find to be within much hollower, than that of Men or of other Animals.[1]
4. Again, I also obſerv'd a Nail of my hand, and found it likewiſe to be made up of globuls, not doubting but that it all grows from globuls protruded.

I have ſeveral times put an hungry Lowſe upon my hand, to obſerve her drawing blood from thence, and the ſubſequent motion of her body, which was thus: The Lowfe having fixt her ſting in the skin, and now drawing blood, the blood paſſeth to the fore-part of the head with a fine ſtream, and then it falls into a larger round place, which I take to be filled with Air. This large room being, as to its fore-part, filled about half full with blood, does then propel its blood backward, and the Air forward again; and this is continued with great quickneſs, whilſt the Lowſe is drawing the blood; ex cept, that at times ſhe ſtops a little, as if ſhe were tired, and recollects her ſelf; (a motion like that, it ſeems, which is in the mouth of a ſucking Infant:) From thence the blood paſſeth in a fine ſtream into the midſt of her head, that being alſo a large round place, where it hath the ſame motion. Hence it paſſeth in a ſubtile ſtream to the breaſt and thence into a gut,
