with critical remarks on the subject of nomenclature. 953 species 

 are enumerated, together with many varieties and some cultivated 

 plants. The table of comparison shows that the Bahaman plants 

 are of southern rather than of United States origin.

Professor Trelease's contribution is entitled " Further studies of 

 Yuccas and their pollination." The admirable work done by the 

 late Dr. Engelmann and by Professor Riley on the cultivated 

 specimens of Yucca filamentosa and Yiicca glaitca is now sup- 

 plemented by field studies of these and other species, and the 

 fascinating life-history of these plants and unconscious allies is 

 approaching completion. Professor Trelease's accomplishments as 

 an entomologist have stood him in good stead in the experimental 

 investigation of Pronuba, so that his results taken in connection 

 with those obtained by Professor Riley, and published in the 

 third report of the Missouri Garden, have given a large number 

 of the more essential facts connected with the plant and its de- 

 pendent visitant. But the mystery of the coordinate evolution of 

 the plant and the moth seems as deep as ever. It is to be hoped 

 that this study which preserves so thoroughly the traditions of 

 its founder's scientific adviser, George Engelmann, will not be 

 abandoned until a satisfactory answer is given. The conjectures 

 before us are fertile. The patient work on which they are based 

 gives promise that before long, even more plausible conjectures 

 may take their place. G. l. g. 



Hesrt Eliason Seaton, A. M., Assistant Curator of the Gray 

 Herbarium, Harvard University, died in Cambridge, after a short 

 illness, on Sunday evening, April 30th. He entered the service 

 of the University during the present academic year and by his 

 courtesy and assiduity commended himself, at once, to all with 

 whom he came in contact. His original investigations in regard 

 to Mexican plants are of a high order and gave promise of great 

 usefulness in systematic botany. 



Mr. Seaton was born in Indianapolis, 15th April, 1869. He 

 graduated in 1890 from Wabash College and became immedi- 

 ately the assistant of his botanical teacher, Professor John M. 

 Coulter. In 1891, he accompanied his teacher, who had assumed 

 the presidency of Indiana State University, to Bloomington, 

 where he became instructor in Botany and Curator of the Her- 

 barium. During that summer he visited southern Mexico and 

 made large collections of plants. The elaboration of these and 

 other Mexican species drew him to Cambridge, where his excel-
