ABSTRACT
Almost all of the original journals were available in the library of the Department of Applied Biology. (Following the closure of the Department in September 1989 the collection, renamed the Buttress Collection, was placed under the aegis of the Scientific Periodicals Library.) Other publications were consulted in the University Library, the Scientific Periodicals Library, and the libraries of the Botany School, the University Botanic Garden, the Shipowners' Refrigerated Cargo Research Association, Cambridge, the International Mycological Institute, Kew, and the Natural Resources Institute, Chatham. I thank all the librarians, and am especially indebted to Peter Filby for his continued interest and assistance.
