to properly conserve specimens more recently obtained

The catalogue of the extensive series of lantern slides 
and photographic negatives has been made complete by 
Mrs. Grace M. Schilling, appointed to succeed Miss Elsie 
M. Kittredge, Assistant Curator, resigned. Mrs. Britton 
has given continued attention to increasing the collection 
of lantern slides, especially of plants not hitherto repre-

on the collection of prints and other illustrations of plants

reference. Contributions to the Emergency Fund were 
credited to the purchase of specimens as follows:
