After this, I mixed new milk with a large quantity of Runnet, to 

 fee whether thofe fin:iller particles v/hich I have before mentioned to 

 have feen fwimming in the whey, would thereby be coagulated, but 

 they ftill continued to preferve their figure. 



Upon examining the before-mentioned filtered liquor by the mi- 

 crofcope, I faw in it an inconceivable number of uncommonly minute, 

 particles, to v.hich, by reafon of their exceeding fmailnefs, I could not' 

 give any other name than that of globules. 



Whether the gLbules or falts in the Runnet, have fuch an effedl: 

 on rain water, as to caufe any of its particles to coagulate, fo as to be- 

 come vifible by the microfcope, I have not yet been able to difcover. 



I feveral times tried the experiment of pricking my finger with a 

 needle, and, immediately mixed fome of this liquor with the blood, to 

 fee whether any of its particles would thereby be coagulated : on 

 viewing the fame through the microfcope, it exhibited a curious and 

 pleafant fpe6lacle of vafl: numbers of the globules of blood, rolling 

 one over another, but they were lb far from being coagulated by the 

 mixture, that they feemed more fluid than before.. 



After this mixture had flood about the fpace of half a minute, 1 

 perceived in it many fmall pellucid particles, which by degrees grew 

 larger, but yet were fo minute, and fo much covered by the circumja- 

 cent particles, that I could not clearly difcover their figure ; but, to 

 the bed of my judgment, they were irregular faline particles, appear- 

 ing all of different fliapes, and adhering together, in like manner as 

 we obferve in fugar-candy. Now, whether this appearance was com- 

 pofcd of lalts in the blDod, or falts in the milk, or both, I am not 

 able to difcover. 



I feveral times applied a drop of the before-mentioned filtered 

 liquor to my tongue, and I judged it to have more of a bitter than an 

 acid tafie ; whereupon I confidered, whether its property to curdle.. 

 milk, might not be derived from the gall.
