phllofophers of great reputation have agreed in fen- 
timent with Mr. Needham, yet I am fatisfied, 
that whenever this fubjeft is taken up again, and pro- 
perly attended to, the world will be convinced they 
have been too hady in their conclufions. 
At prefent I fliall pafs over many other curious 
obfervations, which I have made on two years expe- 
riments, in order to proceed to the explaining a hint, 
which I received lad January from Mr. De SaulTure, 
of Geneva, when he was here j which is, that he 
lately found one kind of thefe animalia infuforia^ that 
increafes by dividing acrofs into nearly two equal 
parts. 
I had often fcen this appearance, in various fpecies, 
a year or two ago ; as I found upon looking over the 
minutes I had taken when I made any new obferva- 
tion ; but always fuppofed the animals in this dividing 
date to be in coition. 
Not healing till after Monfieur De Saudure had 
left this kingdom, from what infudon he had made 
his obfervation j his friend, Doftor De la Roche, of 
Geneva, informed me, the latter end of February 
lad, that it was from hempfeed. 
1 immediately procured hempfeed from different 
feedfmen, in didant parts of the town : fome of it 
1 put into New- river water, fome intodidilled water, 
and fome I put into very hard pump-water ; the re- 
fill t was, that in proportion to the heat of the wea- 
ther, or the warmth in which they were kept, there 
was an appearance of millions of minute animalcula 
in all the infufions ; and fome time after, fome oval 
ones made their appearance, as at Tab. VI. Fig. i.b.c, 
Thefe were much larger than the fird, which dill conti-
