were detasseled, or the ears covered before pollination, no seeds developed. He showed the 

 direct relation of the tassels to seed production by cutting the tassels off of a portion of the 

 ear before pollination, in which case he found that that portion from which the tassels were 

 cut bore no grains. Philip Miller repeated the experiments of Bradley in 1741. In 1750 

 Gleditsch published a learned account of his experiments in the palm. A pistillate palm 

 some eighty years old had never fruited but when pollinated with "male" pollen bore fruit, 

 the seeds of which germinated in 1751. Thus between the time of Camerarius and Koelreu- 

 ter a number of experimenters were investigating sex in plants, but these experiments ap- 

 peared to have had but little influence upon the scientific thought of their day. Following 

 these experiments Sprengel (1750-1816) first showed the extent of insect pollination. In the 

 early 19th century the work of Andrew Knight and William Herbert in England and 

 Gartner in Germany is outstanding. The author shows that there were many breaks in 

 the trend of thought regarding sex in plants up to the time of the publication of Mendel's 

 papers in 1866. [See also next preceding Entry, 90.] — M. J. Dorsey.

 Curtis. Mycologia 11: 181-201. 1919. — The life and work of Curtis as revealed mainly 

 through his correspondence is presented in a thorough manner. He was not only a mycolo- 

 gist but also a student of flowering plants and lichens. He collected lichens at the sugges- 

 tion of Tuckerman (1845) , and then turned his attention to the fungi (1846) . In 1848 appeared 

 his first mycological paper, in which he acknowledges indebtedness to Berkeley for assistance 

 in its preparation. From 1846 to 1872 he corresponded with Berkeley, exchanging notes and 

 specimens of fungi and thus making possible the important mycological contributions which 

 appeared under their joint authorship. Curtis's original herbarium now forms part of the 

 Farlow Herbarium of Harvard University. Among other institutions which are known to 

 have collections of Curtis's fungi are the Royal Botanical Garden, Kew, England; the U. S. 

 Department of Agriculture, the New York State Museum, and the University of Nebraska.

 tions to botany, especially in the field of mycology. The letters of these two botanists to 

 each other and to others are quoted and commented upon. In those days as well as in the 

 world war just ending, the botanist placed his knowledge at the disposal of his country. —
