8TtMULANT EFFECTS ov CA^IPIIOR, S.c. 235 



following : viz. the two leaves became coniiderabiy ele- 

 vated upon their footftalks ; the flower expanded more 

 than I had ever (eea it in any inftance ; the ftamina, or 

 chives, receded from the piiHllum ; the three leaves of 

 thccalix, or flower-cup, v/ere remarkably refleded back, 

 and became extremely rigid, and elailic. The internal 

 furflice of the petals of the flower perfplred conhderably, 

 though I could not difcover a fimilar perlpiration from 

 any of the flowers of the fame plant, in the fame room, 

 and temperature. I did not perceive any perfpiration 

 from the leaves of my camphorated plant. 



At the very time of making this experiment, I was 

 engaged in delivering, to my clafs, lectures on the Irr/-

 of Ihevvingto the gentlemen, the plant which 1 have juit 

 mentioned. Although it was not, at this time, lb lively 

 as it had been before, they all agreed, that it exhibited 

 remarkable appearances of life, health, and vigour. To 

 me thefe appearances were very flriking. 1 could not 

 help comparing them to the effects of a certain quantity 

 of ardent fpirits, or of opium, upon the human con- 

 ftitution. 



My camphorated plant continued in a very invigorated 

 ftate for two whole days : after which it began to droop. 

 The leaves drooped and decayed fooner ihan the flower. 

 The other flowers and leaves of the tulip-tree, which 

 were left in fimple water, did not live more than half 

 the time of that in water with camphor. 



Neither myfelf nor feveral other perfons were able to 

 difcover the leaft odour of camphor in any part of the 

 branch, except what was immcrfed in the fluid. This 

 circumftance feems to render it probable, that the cam- 

 phor was not abforbed by the plant, but that it exerted 

 its remarkable efieds entirely through the folids to whi..h 

 it was immediately applied.
