The Assistant Secretary called attention toa specimen 
of an Orchid, Catasetum deltoideum, standing on the

typical flower being a male and the two below females. : 
Mr. Luke M. Hill presented the following copy of the 
analyses lately made by the Government Analyst, of the 
different artesian well waters in Georgetown and near

with the minutes of the Society. He understood that 
these waters were formerly recommended as a medicine.
