veral Plants in each of them, and accordingly, in each of 
them are leveral Acres of Wheat or Barly ; tor if they were 
not included within them, how could they come out of them. 
And yet much lefs da the Ears of the Wheat, fhew us their 
Wheat Corns, when we Anatornife them, for this great Mi- 
ftery doth remain hid from our Eyes. 
I put this down as a certain truth, that the fhape of a Hu- 
man Body is included in sn Animal of the Mafculine Seed, 
but that a Mam Reafbn (ball dive or penetrate into this Mi- 
ftery fo far^that in the Anatomizing of one of thefe Animals 
of the Makuline Seed, we fiiould be able to fee or difcover, 
the intire fhape of a Human Body, I cannot compre- 
hend. 
As to what concerns my Magnifying-glaflfes,! will not brag 
of them, I make them as good as poffible I can in my 
power, and I muft fay that feveral Years fince, 1 have not 
only Ground them ftill better and better, which is a matter 
of confequence, but I have alfo Mounted ihem better from 
time to time, which is alfo very Material : I have known fome 
that have made Magnifying glaffes^and have bragged of them, 
and yet were not fit to judge, whether a Glafs did difco- 
ver well or no, and feeing that every one is not fit, to judge 
well and truly of a Magnify in;g- glafs, much lefs can he be fit 
, to make new Difcoveries, and thus doing fo, no Body muft 
Publilh or bring to light, new Difcoveries, and judge by 
one fight^but he muft fee the fame over and over feveral times, 
for it doth happen often to me, that People looking through 
a Magnifying-glafs, do fay now I fee this, and then that, and 
when I gave them better Inffrudions, they faw themfelves 
mifVaken in their opinion, and what is more, even he that is 
very well ufed to look through Magnify ing-glaffes, may be 
miflcd by giving toofudden aJudgmenr,of what he doth fee. 
In the meanwhile that I am bufie in Writing thefe, I have 
Sor 10 Magnify ing-glaffes lye before me, which I have fee 
in Silver my felf, and although 1 have never had any 
Inftrudion at all how to Work any Mettal with Hammer or 
File, yec l mount my Glaffes and Tools lb well^ that Work- 
men in Gold confefs themfelves that they are not able to do 
$hfi fame. 
Thefe Magnifying glaiTes Magnify fome more then others, 
and before them ffand^ the Animals, that are in the Mafcu- 
line Seed of Mankind.
