from thence muft be endued with the virtue of that parr. And 

 the pureft part of this blond, being extra&cd Jikc a quintcf- 

 fence out of the whole mafle, is refervcd in convenient recrpta- 

 clcs or vcflels till there be ufe of it : and is the matter or feed, of 

 which a new animall is to be made; in whom, will appear the 

 eflfeft of all the fpecificall virtues drawn by the bloud in its ite- 

 rated courfes, by its circular motion, through all the ieverall 

 parts of the parents body. 



Whence it followeth, that if any part be wanting in the body 

 whereof this feed is made, or be fuperabundant in it; whole vir- 

 tue is not in the reft of the body,or who r c fuperabundance is noc 

 allaid by the reft of the body; the virtue of that part, cannot be 

 ki the bloud, or will be too ftrong in the bloud, and by confc- 

 quence, itrannot beat all, or it will be too much in the feed. 

 And the eflfecl proceeding from the feed, that is, the young ani- 

 mal/will come into the world favouring of that origine; unlcfTc 

 the mothers feed, do fupply or temper, what the fathers was 

 defective or fuperabundant in; or contrariwiie the fathers do 

 correct the errours of the mothers. 



But peradventurc the Reader will tell us, that fuch a fpecift- p. 



call virtue cannot be gotten by concoftion of the bloud, or by TfieJirference 

 any pretended impreflion in it ; unleffe fome little particles of Airhour< opt- 

 the nourifhcd part do remain in the blond, and return back ? lon * andthe

\vith it, according to that maxime or Oebcr, ft^uod non tngredt- 

 tur, nonimmutat no body can change another unlefle it enter 

 into it, and mixing it felf with it do become one wich it. And 

 thatfo in effect, by this explication we fall back into the opini- 

 on which we rejected . 



To this I anfwer, that the difference is very great between 

 that opinion and ours ; as will appear evidently, if you ob'ervc 

 the two following aflertions of theirs. Firft, they affirm that a 

 living creature is made merely by the aflembling togecher of fi- 

 milar parts, which were hidden in thofe bo.iies from whence 

 they are extracted in generation : whereas we fay that bloud 

 coming to a part to irrigite it> is by its paflagc through it/and 

 ibme little ftay in it and by its frequent returns tlvther, at the 

 length tranfmuted into the nature of that part: and thereby the 

 fpecificall virtues of every part do grow greater> and arc more 

 diffufcd and extended. S Se-
