WE regret that Professors Marsh and Cope have considered it 
necessary to carry their controversy to the extent that they have. 
Wishing to maintain the perfect independence of the NATURALIST 
in all matters involving scientific criticism, we have allowed both 
parties to have their full say, but feeling that now the controversy 
between the authors in question has come to be a personal one 
and that the Narura.isr is not called upon to devote further space 
to its consideration, the continuance of the subject will be allowed 
only in the form of an appendix at the expense of the author.
