like plants, but by protrusion or squeezing outwards from within the skin; for 

 what was root at first within the skin, becomes the body of the hair when thrust 

 out. When it is first protruded out of tlie skin it is very soft, but suddenly 

 drying in the air it becomes harder, first without in its bark, and afterwards 

 within, whence the bark being first dried will not shrink as the inward part does, 

 but the inward stringy part shrinking, they necessarily cleave one from another, 

 sometimes with one and sometimes with many clefts, which makes the appear- 

 ance of dark lines in the hair ; these are mistaken for the marrow. 



I have several times this summer walked into our meadows, in order to ob- 

 serve the fresh excrements of cows, horses, and other animals, but I could never 

 yet discover any animals in them : but I found multitudes of these small globules 

 swimming in a clear liquor, some of which were not above one sixth part, others 

 not above a 36th part of a blood globule. I have examined also the thick part 

 of the urine of a mare after she had been hard ridden ; and found that this thick 

 ash-coloured part of it was caused by a great variety of differing globules, some 

 as large as those of blood, and composed of 6 others : these first were like a 

 very close grown bunch of grapes, whence though they were not perfectly 

 round, yet I call them globules ; amongst these I found some -^ of a blood glo- 

 bule, and some -^. In cock's dung squeezed out as soon as killed, I found an 

 exceeding great number of worms like eels, which I found to be the male seed 

 of the cocks. Then I squeezed out the dung of young hens, but I found only 

 one animal, ^ part of a blood globule. It was constituted of a transparent 

 liquor full of globules, -f of a blood globule, these were compounded of 3, 4, 5, 

 or 6 other globules, also many others of -gV of a blood globule. Young pigeons 

 dung about a month old pressed out, had in one no animals; in the second, whose 

 dung was more transparent, were many, so that in the compass of a sand were 

 100 of an egg shape, -|- of a blood globule, moving swift, the rest of the matter 

 was like that of hen's dung.
