We heartily join Mr. Eaton in his caution to geologists to 
pause before they adopt any important innovations in their 
science. ‘‘ The late introduction of a new chemical nomen- 
says Dr. MacCulloch to the Geological Society, 
“has possibly, in conjuction with other causes, excited a 
taste for neology, which it behooves “0 be restrain by every 
method in our power, and it is the of our Society to
