a property of irritability resident in the granules themselves. Mr. 
Sanderson endeavoured to show that, in certain species at least of 
Goldfussia, it is impossible that any such motion of the granules 
can take place, as the necessary condition, viz. the continuity of 
the cylindriform cells with the papille, is absent. After giving a 
description of the different layers of cells of the style, and showing 
the complete separation of the papille of the stigma from the cylin- 
drenchyma of the style, the author concludes, that from these facts 
it is evident that no change of the position of the granules can, in 
the instances adduced, cause any alteration in the position of the 
stigma, and that there seems every reason for supposing that the 
change produced by irritation is confined to the external series of 
cells which in Goldfussia, as in Mimulus, have the property of re- 
sisting the tendency which the organ has, from the elasticity of the 
epidermis, to curve inwards on the application of a mechanical or 
chemical stimulus.

Hardy, Esq. The author stated that he had ascertained that 148 
species of moss occurred within a short walk of Penmanshiel, being 
nearly as many as Dr. Dickie finds within ten miles of Aberdeen. 
5. Dr. Balfour made some observations on the structure of Lyurp, 
a peculiar, hairy, scale-like matter found on the leaves of Eucalyptus 
dumosa. This substance is considered by Newport to be caused by 
the attack of an insect. ‘The nature of it is still involved in much 
uncertainty. It has been analysed by Dr. Anderson, and is found to 
contain a large amount of sugar. The hairs which surround the cup- 
like bodies are marked with strie, which converge in a peculiar 
manner towards a space running along the tube. The tubes contain 
granular and amylaceous matter, which becomes blue by the addi- 
tion of iodine, but the hairy matter surrounding the cochineal insect 
does notdo so. The subject is under investigation by Dr. Anderson ; 
and Mr. Cay, who transmitted the substance from Australia, is ex- 
pected soon to send specimens of the plant with the substance at- 
tached, so as to enable botanists to determine its nature more de- 
cidedly.
