SULLIVANT MOSS CHAPTER NOTES. 
We record with sorrow the death on Monday evening, June 3d (1907), at 
his home at Clayville, Oneida Co., New York, of Mr. Benjamin Davis Gil- 
bert. He suffered not long ago a paralytic stroke, and has since been in 
feeble health so that his death was not entirely unexpected. As a young 
man Mr. Gilbert took up the study of botany, giving attention especially to 
the ferns and later to cryptogams. In his death the Chapter loses a devoted 
friend. 
We have received from Burroughs Wellcome & Co., a copy of “Well- 
come’s Photographic Exposure Record and Diary” for 1907 (United States 
Edition), and on reading it can do no less than advise our readers to send for 
a copy. Address as above, 45 Lafayette street, New York City, enclosing 
fifty-cents. We intend to use the “Exposure Calculator” and other rules, 
etc., during this summer, aud will report later on our success. 
Owing to illness Miss C. C. Haynes has been obliged to delay her series 
on Lophozia species, but we hope to publish the conclusion in the Septem- 
ber number. This also explains her failure to answer correspondence more 
promptly.
