but I ftill wanted to fee this incrcafe, ana to find 
the moment of their multiplication 5 for 1 had rea- 
fon already to fufpeft, from what I had feen with 
a glafs I held in my hand, that thefe clutters did 
not grow infenfibly like plants * but that on the 
contrary, the operation I wanted to fee was per- 
formed in a fhort portion of time. To come there- 
fore at that moment, I refolved to obferve regularly 
for fome time Polypi of this fdrt with my Micro- 
Icope, whilft they mould remain in circumftances, 
nearly as eafy and as natural to them, as thofe they 
were in in their proper habitation. 
' This it was that gave me the fir ft thought of the 
above-dcfcribed apparatus. And when I had pre- 
pared and fixed &very thing, I fetmyfelf continually 
to watch for the 1 moment of the multiplication of 
the cluttering Polypi $ and I then found this moment, 
which I had fo much wifhed to difcover, the very fame 
morning that I ; began to make ufe of my apparatus. 
It was, as has been feen in the paper above re- 
ferred to, in that Tpecies of Polypi^ fome of which 
are reprefented in the yth, 6th, and 7th figures of 
the 2-d plate of the 474th number of the Philo fophi- 
cal Tranf actions, that I firft difcover d the manner 
in which thefe fmall animals multiplied : and it 
is indeed among fcveral fpecies that I am now ac- 
quainted with, one of thofe in which this fa£t is the 
mod eafy to be obferved. 
It is alfo in the fame fpecies eafy to fee that very 
odd motion, which they exhibit at their anterior ex- 
tremity. ! 
This fame motion, which has alfo place in other 
fpecies of cluttering Polypi, is not in them fo eafie
