—The Journal of the Royal Microscopical Society has just com- 
pleted its first decade, and the last number of its tenth volume con- 
tains an editorial “preface” by the editor, Mr. Frank Crisp, paying 
a deserved tribute to his associate editors and especially to Profes- 
sors F. Jeffrey Bell and A. W. Bennett, who for these ten years 
have prepared those abstracts of the biological literature of the 
world which have made the Journal indispensable to every natu- 
“a who wishes to keep up with other subjects outside his speci-

—George W. Tryon, Jr. , the Conchologist, died in Philadelphia 
February 6th, aged fifty years. Although not a Friend, his

engaged in business with his father and brother. The lack of 
collegiate education he amply made up in later life by private

contributions to this favorite science, all showing characteristic 
accuracy of detail and patient research. In addition to these ag et 
he also issued a Bibliography of American Writers on Conchology - 
z 1861 ; a Monograph of the Fresh Water Univalve Mollusca of 
the United States, in continuation of Haldeman’s work on the same 
subject; a Synonymy of the Species of Strepomatidæ in 1865; a
