184 ROCHESTER ACADEMY OF SCIENCE. [June 24, 



In the preface the author says : "To the Rev. Professor Chester 

 Dewey, to whom I am permitted to dedicate this volume, I am 

 indebted for that part of the flora which relates to the difficult, yet 

 deeply interesting, family of the Carices. He has not only granted 

 me access to his former excellent monograph of that genus, but has 

 prepared the article for the present work with his own hand. ' ' 



In 1850 Dr. Dewey was elected Professor of Chemistry and 

 Natural Philosophy in the University of Rochester, which position he 

 occupied until i860. After this time he still continued his studies and 

 observations and maintained an interest in nearly all scientific subjects 

 until his last days. He died in the eighty-third year of his age, 

 beloved and respected by all who knew him. 



In 1868 in connection with a notice of his death the following 

 appeared in the American Journal of Science and Arts, 2 series, 

 XLV. 123: 



' ' Dr. Dewey was an early and a frequent contributor to 

 this Journal upon several subjects, but especially upon that with 

 which his name is inseparably connected — the Carices of North 

 America. His Caricography, commenced in 1824," was continued 

 year after year with few breaks, down to the close of 1866, when it 

 terminated with a general index to species. It is not for us to speak 

 particularly of the merits of this elaborate monograph, patiently 

 prosecuted through more than forty years. This and the monograph 

 of Schweinitz and Torrey laid the foundation and insured the popularity 

 of the study of the Sedges in this country. But while the latter 

 systematic arrangement was published as a whole in 1825, Dr. Dewey's, 

 carried on without particular order, extended through a lifetime, and 

 represents both the earlier and the later knowledge. 



" Botany was one of the occupations of Dr. Dewey's leisure 

 hours; his long life was mainly devoted to education. Turning his 

 attention to a special yet almost inexhaustible subject, however, and 

 laboring perseveringly and faithfully, although under many disadvan- 

 tages, he has permanently and honorably impressed his name upon 

 the science in which the Californian Umbelliferous genus Deweya 

 records his services. He was an excellent, simple-hearted, devout 

 man, a fine specimen of the Western New Englander of the old 

 school. 



"The lovers of Carex, so numerous in this country, will cherish 

 the memory of these two venerable men, Sartwell* and Dewey, long 

 associated in congenial pursuits and gone to their rest together. 



•Dr. Henry P. Sartwell, of Penn Van, N. V.
