f. The deep of plants has been much fpoken of by Llnneus and 

 others, but there is a wonderful circumftance occurs in it, which has 

 not been noticed ; which is, that it feems to refemble the torpor of 

 winter-deeping infecls and other animals, as many plants do not ap- 

 pear to refpire during this part of their exiftence ; for fome vegeta- 

 bles clofe tocrether the upper fcfrfaces of their leaves, both during

Many other plants clofe their petals and calyxes during their deep as 



ill'asin rain, as convolvulus ; and fome even in the bright day- 



ght, as tragapogon ; and yet all thefe plants are believed by gardeners 



) o-row, when young, fader in the night. 



We mud obferve, that this deep of plants, though it may refemble 



th

It 



Id hence appear, that perpetual refpiration is lefs 



dary to the vegetable than to the animal world 



and that as lefs 



wafled during the inadive date of deep, it is poffible th

Dr. Hales and Dr.Walker on plants durin? the bleedine fcafon, the 



afcent of the fap-juice not only dopped during the night, but fome- 

 times became retrograde, which might neverthelefs be afcribed to the 

 torpor of the abforbent fyf^em induced by cold, as well as to that of
