through the leaves. In contradiction to this, I assert, 
that it is perceived much better in the morning, be- 
fore the sun has been able to dry and harden it. 
These persons are, however, deceived. I have not 
only seen this honey-dew fall a hundred times in 
small rain on the leaves of the ash, but I have also 
.shown it to others, and the globules were most dis- 
tinctly to be perceived.” Mr. Huish objects to this 
hold assertion, that honey-dew never appears in 
moist weather, and is the result only of sultry heats : 
and adds, I have long adhered to the opinion, that the 
honey-dew dispersed upon the leaves of trees, was 
only an exudation, although the globules scarcely 
bore any resemblance in form to each other, but 
were rather in imitation a species of rain. On exa- 
mining more particularly diflerent trees, on which the 
honey-dew was apparent, chance led me to the dis- 
covery of an holm-oak on which the honey-dew had 
recently appeared, and in its primitive form, which is 
that ol a transpired humour. The leaves were co- 
vered with several thousands of globules, or small 
round and compact drops, without, however, touching 
or intermixing, similar to those which are seen on 
plants after a thick fog. The position of the globule 
seemed to indicate, not only the point from which it 
exuded, but also, the number of pores or glands of 
the leaf in which this mcllihuous juice had been iire- 
pared. I assured myself, that the honey-dew pos- 
sessed the real colour of honey, which of itself, was 
sufficient to decide on its origin without removing the 
doubts, which a contrary prejudice establishes. The 
honey-dew of a neighbouring bramble had not the 
same distinct appearance ; the little globules had no 
doubt commixed, or being united to each other, 
either by the humidity of the air, or by the heat 
which had dilated and extended them, they formed 
large drops, or broad layers, the dried matter of 
which, had become more viscous. It is under these 
latter forms that the honey-dew tg commonly per-
