kringhfs^ Borelh/s, Malfighhfs^ and Others? too many to be nicely 
quoted, fince we have among us in the XJniy QtRty, eye -whrie/Ses 
enough in moft of the cafes recited. 
The part moft ufually affed:ed is the right Ventricle of the 
heart, and thegenm -uemfum^ where the blood returning frora 
the habit of body, flow in motion, impoverifht and difpirited 
moreeafily admits fuch a concretion : yet the left Ventricle 
^ and the gmm artenofum frequently breed the like,fuch was that 
jTWp/^Af mentions, branching o;nt into the Aorta and Vena Pulmo- 
mofiarh^ in a perfon who di^d of a grievous Apoplexy, and 
fuch Weffer makes one gnat caiife of Apoplexies. Xhe linus's of the 
brain alfo often harbour them, as we have found in one that 
had an obftinate Headachy and at laft died mad , and not long 
lince in another, who once had fome fits of a Frenzy^ and at 
length died epileptical, in both which cafes the fim/s kngitudi- 
nahs was full of a Poljpm^ which emitted very tough branches 
into all the httle lateral veflels, and Blafius gives the like ac- 
count in a mad' Man s brain, who at laft died convulft. 'Twere 
eafy toamafs together many Obler various of this nature, 
but upon the ftreis ot , thefe already brought tis reafonable to 
aflTert, that a Poly^u^ is fo far from being a product: at the pe- 
riod of a difeafe, that it feems rather a ftated fettled caufe as 
well as an immediate occafion of the fatalfymptoms which'at- 
tend the moft incurable diftemperss thus if in the heart it grow 
15 laTge as to force a Diafiole beyond the due tenfion of theF/i'm, 
it produces a mortal Sjncc^e 5 if fmaller and not exceeding the 
confines of the Ventricles* a ftrong and irregular pulfe fuc- 
ceeds, and there muft be a pa/pitattcn of the Heart to maintain 
life i if it fend branches into the larger pulmonary veffels, 
the motion of the blood is retarded; and the breaft and lung$ 
labour under their load in an AJihma : or if it reaches the ca- 
pillaries, a Ftripnet^mony^ anUlrer^ and at Ij^H a Conjur^ftkn is at 
hand if the concretion begins in the fmall vellels of the 
Tleura^ then a Pkiirijy follows, if it grows and fixes in the lar- 
ger veflels of the arms, legs,or the like, painful varices appear, 
and probably Rhe^mtiJ^s owe muchof th^k pain to fome fuch 
concretions begun in the capillary veflels of the habit of the ' 
Body. Again, when thefe bodies are in the Stnus of the Braw^ 
if fmalJ, the veflfels will only be a little dittended, andfo a 
patn in the head may fuffice, but if larger,' the obftrudtion increa- . 
fes, the blood and fpirits are caft into an hurry, the brain is 
inflam'd, the fenfes prefently are diforder d in the apprehen- 
fion of their pbje^ls andfo a Fw/^y/ feizes the man ; if yet they 
chance to be bigger and fill the <S^W more, the hlojdfentuf ',
