Ward writes: 'I thought I could not better respond to the honour of the invitation to give the Croonian Lecture this year than by choosing a subject from the domain of plant pathology, which should, at least, have the merit of being of general interest and importance, and it seemed probable that an account of some of the more conspicuous features and recent results of the study of certain fungoid diseases might be so placed before you that it should illustrate not only the kind of progress which plant pathology is making, but also show how dependent that progress is, and must be, on the advances of physiology.'

Annotations in pencil and ink. Includes one figure of a diseased plant.

Subject: Botany / Pathology / Parasitology

Received and read 27 February 1890 [cover of paper stamped 28 February 1890].

The Croonian Medal and Lecture is the Royal Society's premier lecture in the biological sciences. The lectureship was conceived by William Croone, one of the original Fellows of the Society. Among the papers left on his death in 1684 were plans to endow two lectureships, one at the Royal Society and the other at the Royal College of Physicians. His widow later bequeathed the means to carry out the scheme. The lecture series began in 1738.

A version of this paper was published in volume 47 of the Proceedings of the Royal Society as 'Croonian lecture .— On some relations between host and parasite in certain epidemic diseases of plants'.
