Vegetable Stanch. 



Dr. Keill, by eftimating the quantities of 

 the feveral evacuations of his body, found 

 that he eat and drank, every 24 hours, 4 

 pounds 10 ounces. 



The Sunflower imbibed and pcrfpired in 

 the fame time twenty two ounces, lb the 

 man's 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 deducting five ounces, which 

 Dr. Keill allows for the faces alvi , there 

 will remain iixty nine ounces of frefh li- 

 quor, which enters a man's veins? and an 

 equal quantity paflcs off every 24 hours. 

 Then it will be found, that feventeen times 

 more new fluid enters the fap veffels of the 

 plant, and paflcs off in 24 hours, than there 

 enters the veins of a man, and pafles off in 

 the fame time. 



And fince , compared bulk for bulk, the 

 plant perfpires feventeen times more than 

 the man, it was therefore very neceffary, by 

 giving it an extenfive furface, to make a large 

 provifion for a plentiful perforation in the 

 piant, which has no other way of difchai--
