Rh at my leisure. I found them not to differ from what I gave an Account of in my Letter of the 4th of Novemb. 1681. unless it were that some of the hairs in these supposed worms were so tender, that they broke in two upon the least touch, Other worms seem'd to be a bundle of hairs, but when I went to seperate them, it was just as if I had toucht a' soft fat body.

I squeezed some black specks out of the thick of my own Nose, which I saw to be bundles of hairs, I then took out hairs from one of them to the number of 36.

Fig. A. B. C. D. E. is a bundle of hairs, as it appears in a Microscope, the part A. B. C. before I took it out of my Nose, lay even with the skin, and appear'd like a black speck; the hairs were not all of a length, but one stood out more than another, as at B. a single hair standing out as B. was transparent, and in the lower part oi the bundle C. D. E. A. all the hairs together were transparent. parent. In some bundles of hairs the part next the skin lay quite even, as if it had been cut with a pair of sizers. B.

I took the worms out of the Noses of 2 other persons, and I found the number of hairs in a bundle, to be from 3, 4, 5, 6, and 9. to 25, and 30. when the worms lay deepest in the Nose, they seldom contained any hairs, unless the person they came from were very black, and then the hairs were more easily perceivable.

In the pressing out of worms, I could tell whether there were hairs in them or no, for if the substance came out streight, then there were always hairs, but if bended and bow'd, none.

The make and conformation of these worms, I suppose to be after this manner. When the Root of a hair lying deep in the skin, supplies so much nourishment as to make the hair grow out and appear upon the face, the upper part of the hair by rubbing, or some other violence, comes
