1847, in three different situations.

These tables, extracted — No. 1, from the Gardeners' Chronicle of Saturday, 31st, 
and No. 3 from the Regents Park register, by Mr. White, who resides in Old 
Kent Road ; will exhibit the great differences that exist in localities not very remote, 
No. 2 stands intermediate, and proves, that at 10 miles south of London, the lowest 
temperature by night, and the maximum by day, exhibit none of those extremes 
which characterise the " readings-off " of the Chiswick thermometers. We thus 
obtain convincing proofs that solar heat and terrestrial radiation produce varying 
effects, and that much dependence cannot be placed upon local tables. In gardens, 
a thermometer ought to be laid on the grass, another some distance over it, a third 
with a muslin shade strained some distance over it; and, thus proceeding, a few more 
facts maybe ascertained. 
ON THE CULTIVATION OF SOME OF THE PLANTS 
BELONGING TO THE GENUS IXORA. 
Those who have been, or are at the present time, successful in the management 
of the plants constituting this splendid genus of stove plants, can scarcely believe 
it credible that the Ixoras, by the great majority of culturists, should be regarded as 
plants of difficult cultivation. Yet such is the fact ; for, go where you will, and 
except under the management of some of the principal contributors to the metro- 
politan exhibitions, you will rarely see a plant well grown, and still more rarely well 
bloomed. Now, the reason of this is, not so much the result of w T ant of attention, 
as over-care. Somehow or other the general, but at the same time most fallacious, 
opinion is, that the Ixoras are plants of very delicate constitution, requiring very 
tender treatment at all times, and in every situation; and hence, like delicate 
children, are so nursed and coddled, as, ultimately, to be nursed to death. Unfor-
