5. Ill refped to vegetables acquiring affociatlons of motion, or ha- 

 bits of action, the former is feen in the abforptions and circulations of 



r 



their fluids, and in the various moven:ients above defcribed ; which 



w 



whirl their leaves or tendrils, and clofe or open their corols and ca- 

 lyxes, which could not be performed without the fynchronous and 

 aflbciated a6lions of many mufcles ; as in the abforptions and circu- 

 lations of animal bodies, and the movements of their limbs. 



Other acquired habits of vegetable actions appear from the grains 



and 



roots brought from more fouthern latitude 





which germinate 



here fooner than thofe which are brought from more northern ones, 

 owing to their acquired habits. Fordyce on Agriculture. And from 

 the apple trees fent from hence to New York, which blolTomed for a 

 few years too early for the climate, and bore no fruit ; but after- 

 wards learnt to accommodate themfelves to their new fituation. Tra- 



vels in New York by Profeffor Kalm. 



The divifions of the leaves of the fenfitive plant have been accuf- 

 tomed to contrad at the fame time from the abfence of light ; hence 

 if by any other circumftance, as a flight ftroke or 

 flon is irritated into contra(9:ion ; the neighbourins: ones contradl alfo. 

 from their motions being aflhciated with thofe of the irritated part. 

 So the various fl:amlna of the barberry have been accufl:omed to con- 



and thence, if you flimulate one of 

 them with a pin, according to the experiment of Dr, Smith, they all 

 contrail from their acquired aflbciations. 



6. This leads us to a curious inquiry, whether vegetables pofl*ers 

 any organs of fenfe ? Certain it is, that they poflfefs a fenfe of heat

njury, one divi 



tradl together in the evening ; 



and cold, another of moifture and drynefs, and another of light and 

 darknefs ; for they clofe their petals occafionally from the prefence 

 of cold, moifture, or darknefs. And it has been already fliewn, that 

 thefe anions cannot be performed Amply from irritation, becaufe cold 

 and darknefs are defedive quantities of our ufual flimuli ; and that 

 Oil that account fenfation or volition are employed ; and in confe-
