THE BOTANISTS OF PHILADELPHIA. 373 



the public school, and graduated, with honor, from the 

 Central High School in 1S74. In 1875 he entered the 

 Academic Department of Brown University, graduating in 

 the class of 1879. At the time of graduation Charles Boyer 

 was honored with the position of class poet. In 1885 

 he received from Brown University the degree of A. M. 

 Since graduation he has been engaged in teaching mathe- 

 matics and the classics, and is, at present, a school supervisor 

 of Philadelphia. 



As a boy, his botanical education was chiefly gained 

 from rambles around Philadelphia, his botanical collection 

 quite extensively representing the flora of Pennsylvania, 

 together with portions of New England. But for many 

 years Professor Bover's entire attention has been given to

microscopical work, more especially to the group known as 

 the Diatomacese. His collection includes several thousand 

 slides of separate named forms, the result of hours of work. 

 His library includes as large a number of works on 

 Diatomacete as will probably be found in a private col- 

 lection in this country, the result of many years collecting. 

 Professor Bover's papers, thus far published, consist 

 entirely of contributions to scientific journals, including 

 articles on microscopic technique in the Observer, and others 

 on the Diatoms in the Bulletin of the Torrey Botanical Club. 

 His papers on botany are : " A Fossil Marine Diatomaceous 

 Deposit at St. Augustine, Florida " ; "A Diatomaceous 

 Deposit from an Artesian Well at Wildwood, New Jersey." 

 A translation of the latter paper appeared in a Parisian 

 journal, Le Diatomiste, Vol. II. " The Mounting of Diatoms," 

 Practical Microscopy, January and May, 1895.
