1 1 Vegetable Statich. 
Dr. Keilly by eftimating the quantities of 
the fevcral evacuations of his body, found 
that he eat and drank-, every 24 hours, 4 
pounds 10 ounces. > 
The Sunflower imbibed and perfpired in 
the fame time twenty twO' ounces, fo the 
maiVs food, to that of the plant, is as 74 
ounces to 22 ounces, or as 7 : 2. 
But compared bulk for bulk, the plant im- 
bibes feventeen times more frefh food than 
the man : For deducing five ounces, which 
Dr. Keill allows for the faces alvi y there 
will remain fixty nine ounces of frefh li- 
quor, which enters a man's veins; and an 
equal quantity pafles off every 24 hours. 
Then it will be found, that feventeen times 
more new fluid enters the fap velTels of the 
plant* and pafles off in 24 hours, than there 
enters the veins of a man, and paflTes off in 
the fame time. 
And fince , compared bulk for bulk, the 
plant perfpires feventeen times more than 
the man, it was therefore very neceflary, by 
giving it an extenfive furface, to make a large 
provifion for a plentiful perfpiration in the 
plant, which has no other way of difeharg- 
ing fuperfluities; whereas there is provifion 
made
