When they became thus vifible, I cut off with a 
fni all Pair of Sciffars the vegetating Extremity, and 
plac’d it in a concave Objedt-Glafs with Water. 
The Plants then took a new Direction, follow'd 
the Expanfe of the Fluid, and continued to vegetate, 
while I fupplied them with Water, which I did from 
time to time, covering them after Obfervation with 
another concave Objcft Glafs, to prevent the Fluid 
from evaporating too fall. Thus I had for the Sub- 
ject of my Obfervations what I may call a microfco- 
pical Ifland, whofe Plants and Animals foon become 
fo familiar to me, that I knew every animal Species, 
and every individual Plant almofl without any Dan- 
ger of Miflake j an Exa&nefs fo neceffary, that it 
would not otherwife have been poffible to follow 
the Procefs of this Vegetation without Confufion. 
From this time I laid afide the Ufc of large In- 
fulions, and provided a certain Number of Watch- 
Chryflals, or concave Objefl-Glaffes, for every Por- 
tion of animal or vegetable Subfiance I was to ma- 
cerate in Water. The Ufe of thefe is plain and eafy ; 
many fruitful little Iflands of various Kinds with 
Labels and Dates affix’d to each may thus be ob- 
tain’d, by placing the vegetating Subfiances in thefe 
Glaffes; and this is the Method 1 would recommend 
to all thofe who ffiall be defirous to repeat or pur- 
fue my Experiments. 
1 find my Subjeft grows upon my Hands, and I 
am unwilling to take up too much of your At- 
tention: 1 ffiall therefore finifh thefe Obfervations 
by annexing a Figure of my Wheat-Ifland and its 
Productions, all which will be fufficiently intelli- 
gible without any more Words 5 and 1 fhall referve a
