 California, and proposed a field meeting for the investigation of one 

 at the Potrero' next Saturday. 



Dr. Cooper gave an interesting account of several small caves in 

 El Dorado county, including the well-known Alabaster Cave. No 

 human or other animal remains have been found in any of these, 

 but may be hereafter, when they are examined carefully. One 

 cave described, which was used as a dance-house by the miners 

 twenty years ago, contains three chambers of about forty, twenty 

 and twelve feet square, or round, respectively. In one of these 

 caves Dr. Cooper saw a bunch of bats clinging in one mass, at 

 which he fired his gun, killing twenty at one shot. They proved to 

 be of a species not heretofore found in California, the Synotus 

 Toivnsendii, mentioned on page 6 of this volume.
