Yet different from the nature of blou » the white and ragged parts thereof, being preci- 
pitated fey the contiguity of thofc unlike partf, are in the large folds of the Hearts right

neration of the ftone in rhe Pelvis of the kidneys, or in the concrcion of Tartar in water 
Conduits. Bur, befides this, the Au hor conceives, that the Pol)pismay be ge erated 
from other cau c, fince Experience evinas, that it is produced by poifonous potions, by 
malignant Fevers, caufed chiefly by a miifma or corruption of the Air, and by the Plague, 
and other infectious Diftcmpers ; wherein it happens, that fuch fteams or juyces are, by the 
corrupt ferments of the Vifccra, mixt with the Bloud, which difturb its texture. This 
our Author illuftrates by fome Experiments > whereof one is, that powring 0)1 of Sul- 
phur, or of Vitriol upon warm blou -V it raifeth it, and by a kind of co&ion at lafl incru* 
Jtates it : Another^ that thr iving pulverifed ^ZJawonir, it renders it black and aduft. 
But that Niter either pulv rifed or diflolved per delifuium, attenuats it, and renders ic 
veiy florid ; as alfo doth Jq.?a vita, Sul gemm.e. Common Silh Sal Armeniic, Sulphur t 
arid-Harts horn \ which alio for a p'retry while hinder the coagulation of tb* bloud. And 
dif.ourfing from hence of the caufes, which in the Plague, &c. do coagulate the bloud>ei- 
ther in who e, or in part by ^crating. Polpus's, he faith, that ihofe caufes ought to be 
taken from fomething a; alogous to Attn , Vitriol land, he like, not from Niter and Vol 4' 
'tilt Spirit' 3 which ihould rather be uted as remedies by rc- fermenting and rendring fluid

What Galilao lali $i undertook, after he hsd difcovcr'd the Sitellits of Jupiter* of - 
giving an eafy and furc w;,y to know the Lo'gitudtsby acaeful Obfervation of thofc Sta^i 
Signior Caffini feemsto have now performed more fully than others, by compofing certain- 
Tables, after i $ years Obfervations made with exatifiefsof the motion of the faid Sarellitf. 
Thefe Tables are contain'd in this B uk 5.. and for the verifying of them, he hath added the 
Ephemtride s of thofe Stars for the year lately elapfed, vi\ A. 166B. Whereupon the Au- 
iho-r hath been deGred from hence, that, if he have calculated any more ^phemerides of them 
lor any foi' owing yearr 3 he would oblige the Cu.ious by timely publishing them for obfer- 
vation. Mean time the French Philolbphers at Paris have acquainted us in the Journal d:s 
Scavans of Dec.17.166Q. with the Obfervations made by them, to verifie the laid Ephemt- 
rides, by a Telefcope of 14 foot y which may be of ferviee to^thofe, that have made obfer- 
vations elfew here at the fame infant and with the lame accuraterrefs, to know the difference
