branch d r which I had cut off in a known

which had a column of water 7 feet high, 
preffing upon it all the time. 
This again (hews the great power of per-

in the fame time , thro' the long flender 
parts of the branch r (Fig. 5.) than was 
preffed thro' a larger ftem c b (Fig. 4.) of the 
fame branch ; but 1 3 inches long with 7 
feetpreflure of water upon it, in the tube^^. 
I tryed in the fame manner another ap-

20 ounces, while only 8 ounces pafled thro* 
the ftem cb^ (Fig. 4.) which had the column 
of water on it. 
The fame I tried with a quince branch, 
which in 4 hours day imbibed 2 ounces
