Mafculine Seed of any Animal fo as ic is^ tVtn the Multitude 
oi thefe Animals do not only deceive our fight, but they alfo 
hinder the exad infpedion and contemplation of them. 
But I take only a little thereof the bigucfs of a Pins-head, 
and mix it with a common drop of clear and clean Rain 
water. This fiuff thus mixt, I fpread about, and that fo 
thin as I can pdflibly even to the greatest extremity, on a ve- 
ry ciear Glafs, that I have by me ready made tor that pur- 
pofe, and in fb doing, I do not only bring a thinner Watry 
moifture about the Animals^ but they lye difperfed in many 
places fo far afunder, that they do not touch one another. And 
thus doing 1 reckon to be the teft way and means, to con- 
template thefe Animals in the ground with the urmoft ac- 
curacy that is poflible. Part of thefe fpiead Animals, I fix be- 
fore fuch Magnifying- glafs, as 1 Judge to be moft convenient 
for that purpofe^ and thus they leem to lye before my fight, 
as in-open Fie^d, which I contemplate in a clear day, and 
fometinies by Candle-light, and to have ftill more light, I 
ufe fometimes a metal Concave Looking glafs, but above 
all things you muft have a care, not to make your view 
in the Sun Ihine, for if you do fo, the Circumference of 
each Animal^ will have almoft as many Colours, as we (ee 
in the Rainbow. 
I have alfo obferved, that between thefe Animals, did lye 
feme fmaller Roundifh parts, and thefe have fecnied to me, as 
if they had Tails,wherefore I took into c6nfideration,whether 
thefe parts might not be young AniraaIs,for certainly thefe 
Animals ftall procreate, and from fmall ones grow to their 
perfed bignefs, and who doth know, whether thefe Animals 
do not come tp their per fed bignefs in the fpace of Twenty 
Four hours, as we have obferved in fmall Water Animals, and 
alfo, if any of ihefe Animals come to dye, fhey do not ferve 
as Food for the growing of the reft. 
And thus I imagine that I have fatisfied the defires of the 
Author, to confer my Obiervations, and togive my opi- 
nion thereabout 5 which i think I cannot better Addiefs than 
to You.
