xl Mr. W. A. Lewis on Nomenclature. 
fall a sacrifice ; for we have seen what is coming, and in a brief 
space of time we shall have lost our opportunity for good. 
The rule of priority was first enacted in this country. The 
movement we are considering originated at a meeting, nearly 
four years ago, of this Society. The approval which some 
sentences of my own were fortunate enough to attract led to 
the proposal being developed and supported by reasons given 
at length. Some discussion followed; and that was in turn 
succeeded by the signature, by an imposing number of our 
body, of a protest having for its object the suppression of the 
new names introduced. The movement is to a great extent 
the child of this Society ; and I was anxious at this critical 
time to bring it again before those with whose support it has 
sprung onwards as it has. I hope enough vis remains to carry 
the movement forward to the end, that it may be not merely 
a welcome proposal, but also an effectual success.
