DE. BEETT-INJUEIES AND DISEASES OF PLANTS. 
the best method of proceeding in studying the subject. He replied: 
“ You would find, I think, a great charm in the study of the 
diseases of plants; but as to ‘ what to read/ it is difficult to tell. 
There are ten or twelve admirable books in German, and one or 
two in French, but not one, as far as I know, in English. You may 
find several short but good papers in the ‘ Gardeners’ Chronicle,’ 
and among them admirable ones, some 20 years ago, by Berkeley 
(the best that I have read in English),* 1 and there are some in the 
later volumes of the ‘ Transactions of the Pathological Society,’ and 
a good one by Mr. Boger Williams was read at the last meeting 
of the Society, and published in the 1 Lancet ’ of the 2nd of 
February, 1889. But really, for an introduction to what may be 
studied on the ‘ Injuries and diseases of plants,’ I do not know in 
English anything but Berkeley’s papers, and an address of mine 
which was printed some years ago in the ‘ British Medical Journal.’ ” 
My object at present is only to bring the subject before the 
notice of our Society, and to ascertain if we may rely on the help 
of our members and others, especially of gardeners and horticul¬ 
turists, in furthering its study. 
* I cannot find these papers, hut in the ‘ Journal of the Royal Horticultural 
Society,’ vols. i-ix ( 1846 - 1855 ), there is a series of admirable papers by the late 
Rev. M. J. Berkeley on various diseases of plants caused by fungi. There are also 
papers by him on the same subject in Hooker’s ‘ Journal of Botany,’ vol. i 
( 1849 ), the ‘ Journal of the Linnean Society,’ vol. i ( 1857 ), etc. A short but 
interesting and suggestive paper on “ Moss Parasites” by Berkeley will be found 
in the £ Intellectual Observer,’ vol. ii ( 1863 ), p. 8 .—Ed.
