Mycology and Plant Pathology 
New Printing 271 Illustrations 12mo, xiii+779 Pages Cloth $4.00 
By JOHN W. HARSHBERGER, Ph.D. 
Professor of Botany, University of Pennsylvania 
It covers an unusually wide experience in morphology, classification and 
physiology of the fungi and the advanced cultural and inoculation methods 
used by the practical bacteriologist and mycologist at the present day. It is 
the first American book to deal with plant diseasss in a general way and to 
combine an account of specific diseases with general mycology and pathology. 
The author has brought together much material which, without this work, one 
must seek in scattered and more or less inaccessible form.
