A day out with conchological royalty

摘要

In the archives of the American Malaco-logical Society at the Academy of Natural Sciences of Drexel University in Philadelphia, I found two sheets of small monochrome photographs commemorating a lost afternoon in a bygone conchological era. Through the camera's lens - and the somewhat variable angles suggest this was a handheld model - we see seven of the giants of the science enjoying a fine day at the Falls of the Potomac above Washington DC, in May of 1910.
