4. Incident which suggested the invention of the case; with remarks on 
the mode in which a smoky atmosphere proves injurious to vegetation. 
-—Having thus described the apparatus in which the plants were confined, 
the soil in which they have been grown, and the progress they have made 
under the peculiar conditions in which they have been subjected to the 
combined action of the several agents concerned in promoting vegetation, 
it is proposed next to consider how plants naturally inhabiting such 
different climes, and possessing such different characters, should be able, 
not only thus to live together, but to flourish in circumstances foreign, in 
many respects, to the native habits of all. Perhaps the best mode of 
dealing with this question will be to compare briefly the conditions to 
which they are submitted in these close cases, with those to which they 
are naturally exposed in the free atmosphere. 
Before entering on this investigation, it may not, however, be out of 
place to advert to the origin of the invention which has just been 
described. From his early youth, Mr. Ward had been attached to bota¬ 
nical pursuits; but, living in a situation enveloped in the smoke of 
numerous manufactories, he had been compelled to give up the cultivation 
of plants, after many unavailing trials. At length a simple incident put 
him on new experiments, and. led him gradually to the results we are 
about to detail. He had buried the chrysalis of a sphinx in some moist 
mould, which was contained in a wide-mouthed glass bottle, covered with 
a lid. In watching the bottle from day to day, he observed that the 
moisture which, during the heat of the day, rose from the mould, became 
condensed on the inner surface of the glass, and again fell back to the 
mould, so as to keep it always in a state equally moist. About a week
