GROWTH OF PLANTS IN CLOSED GLASS VESSELS. 505 
I ysiological inquiries which may now be made with much 
- greater facility and certainty than heretofore; but I wish to 
_ direct the attention of the members of the British Association 
to the development of animal life upon the same principles. I 
am quite certain that a great number of animals would live and 
_ thrive under this treatment, and I can see no reason why, at the 
same time that our stoves are ornamented with Rafflesias, they 
‘ pay not be illuminated with Fulgoras and Candelarias. 
Letter from Messrs. Loddiges to Mr. Ward. 
Dear Sir, Hastings, 8th Sept., 1837. 
Ve have much pleasure in stating, that among the many cases 
of plants which we have received during the last three or four 
a. wherever your instructions have been strictly attended to, 
e success has invariably been complete ; the failures which 
] have occurred have been where neglect had manifestly taken 
place, either by keeping them in the dark, or in some cases by 
breaking the glass. We remain, dear Sir, 
Very sincerely yours, 
C. Loppices & Sons.

x DavuBeEny, of Oxford. 
To James Yates, Esq., Secretary to the Council of the British Association for 
the Advancement of Science. 
Dear Sir, Oxford, July Ist, 1837. 
As it will not be in my power to attend the meeting at Liver- 
Bol: Tam Cesipes of Con ena to you the results of a 
Serowth of cy aoa confined in glass vessels, as a proof at least 
_ that I have not altogether neglected the researches recommended 
_ by the Association to the attention of the Committee of which 
we are joint members, although the preparations for a journey 
_ into a distant land have very much curtailed my opportunities 
_ of prosecuting them. 
’ - During the last week in April I introduced a considerable 
qumber of living plants into glass globes, having only a single 
_ aperture through which air could circulate, and that one covered 
_ over by asound piece of bladder closely attached to the edges of 
the glass, so as to preclude the possibility of any air entering 
the vessel except through the membrane itself.
