THE EFFECTS OF CAMPHOR ON CUT FLOWERS, AND PLANTS 



GROWN IN POTS. 



BY Mil. CHARLES CLARK, OF I.KIPSIC ROAD, CAMBERWELL, LONDON. 



The stimulant effects of Camphor upon the human and some other 

 animal bodies are well known, but those on vegetables are not only 

 new, but very astonishing in their nature. 



A tulip bloom, with two leaves on it, taken out of a stand of tulips 

 that were apparently in the same state of health, was placed in a pint 

 of water which had been stirred up for some time, in a hot state, to 

 dissolve half an ounce of good Camphor, while the other flowers in 

 the stand, which had the benefit of the fresh water, were quite droop- 

 ing, leaves of that placed in the Camphor-water elevated themselves 

 considerably on their footstalks, and the flower expanded more than 

 in its natural growing state; the stamens receded from the pistillunn 

 and the three outer leaves of the calyx, or flower-cup, were remark- 

 ably reflected back, and became extremely rigid and elastic. The 

 internal surface of the flower perspired considerably, though a similar 

 perspiration could not be perceived in the flowers that were in the 

 stand of pure water, although they were in the same room, and of 

 equal temperature. 



The camphorated flowers continued in a very invigorated state for 

 three entire, /days, after which they began to droop ; but the leaf 

 decayed sooner than the flower. The other flowers in the simple 

 water did not survive half so long in afresh state before they drooped, 

 and on then placing them in a solution of Camphor, revived them 

 considerably. Notwithstanding the surprising effect the Camphor 

 so applied produced, no odour or smell of it could be traced in any 

 part of the tidip flower or leaf,' except that portion which had been 

 immersed in the camphorated water. This circumstance seems to 

 render it probable that the Camphor was not absorbed by the bloom,
