Moreover, I examined the artery which I had thus cut afunder, 

 in that part of it which was near to the animal's body, and where 

 it was alfo divided into many fmaller branches, in order to fee 

 whether the circulation was there continued, and with great pleafure 

 I faw, that the courfe of the blood was not interrupted, only it pro- 

 ceeded with a fomewhat flower motion. 



Hence I plainly perceived, that when any part of a limb is cut 

 off, the circulation of the blood will continue in the veflels that are 

 not wounded, efpecially if the efFufion of blood from the veflels 

 which are cut afunder can be flopped. And we may alfo, from this 

 experiment, be well afllired, that there is no artery, which is not 

 throughout the whole of its courfe divided into fmaller branches, 

 whereby it by degrees becomes fmaller, until the very fmalleft 

 ramifications return back towards the heart, and conftitute what 

 we call veins. 



A portion of the blood taken from this crab's foot I examined by 

 the microfcope, to difcover, as far as I was able, of how many 

 parts each globule of blood was compofed ; and I concluded that 

 each globule was compofed of fix diftind; globules, as in the human 

 blood : moreover, I faw that the globules of crab's blood, when 

 brought into conta6l, coagulated in the fame manner as the blood 

 in an human body, though, till this time, I had been of opinion that 

 the blood of fiflies would not be difpofed to coagulate, becaufe we 

 do not obferve any heat in it. 



I expofed a portion of the thinneft part of this blood to evaporate 

 in the open air, in order to fee whether, in that thin part called the 

 ferum, Ifliould difcover any particles; and, in doing this, I faw fo 

 many particles, which, to my eye, appeared fpherical, that the whole 

 fubftance feemed compofed of them and no other, and, upon rtir- 

 ring the fubftance with the point of a needle, thofe particles came still 

 more diflin<illy into view. 



Moreover, I difcovered a great number of faline particles, which, 

 upon the leaft application of heat, coagulated in irregular parts.
