XII. — Annual Report of the Consulting Botanist for 1875. 
The results of the experiments instituted by the Society, in con- 
nection with the potato competition of 1874, have been digested 
and arranged by me, and published as a Report in the recent 
number of the Society's ' Journal.' A short Paper, placing 
before the members of the Society the observations of VV. G 
Smith, Esq., F.L.S., on some points in the history of the potato- 
fungus, was also written by me during the past year, and pub- 
lished in the ' Journal.' 
Throughout the year I have carried on an extensive correspond- 
ence with members of the Society and others, in regard to these 
experiments and the nature of the disease which affects the 
potato. The whole subject has received fresh attention, and a 
better jjirection in the public press, through the action of the 
Society. 
I have again supplied members who have applied to me with 
information regarding the general character, and especially the 
germinating powers of their different crop seeds. 
My attention has been drawn by members of the Society to 
various diseases or injuries affecting their growing crops of 
wheat, oats, turnips, and potatoes, which have been investigated
