The present paper contains the results of investigations on silver-leaf disease which are a continuation of those previously described by one of us (1,2) in earlier numbers of this periodical.
Some time ago it was thought desirable to duplicate as far as possible in different localities the experiments conducted on this disease. Hence most of the experiments described in this paper have been carried out both at Cambridge and at the John Innes Horticultural Institution, Merton.
