Ryncliospora which I failed to recognize and which proved to be 

 R. rariflora, a species not previously reported from north of 

 North Carolina, so far as I can ascertain. This adds one more 

 to the list of southern plants that have recently been brought to 

 light in the southwestern portion of the Cape May peninsula.

Kellogg's Darwinism To=Day.* 



This timely and welcome volume is intended " as a means of 

 orientation in evolutionary matters for the general reader and for 

 the unspecialized but interested student of science." The con- 

 troversies instigated by the publication, in 1859, *^^ Darwin's 

 Origin of Species, have undoubtedly won complete victory, at 

 least among scientists, for the theory of evolution ; but strange 

 as it may seem, these same controversies and the underlying 

 investigations instigated by Darwin's work, have not resulted in 

 establishing the validity of the particular method of evolution 

 elaborated in the Origin. Quite to the contrary, as Kellogg 

 says, "The fair truth is that the Darwinian selection theories, 

 considered with regard to their claimed capacity to be an inde- 

 pendently sufficient mechanical explanation of descent, stand 

 to-day seriously discredited in the biological world." While 

 several alternative and supplementary theories have been ad- 

 vanced, none of them has met with anything like a general 

 acceptation, and Professor Kellogg well expresses our present 

 statu quo when he says, " we are immensely unsettled." 



In addition to winning the battle for evolution, by whatever 

 method, the above-mentioned controversy has taught us the 

 fund^.mental lesson that the question of method can never be 

 settled by polemics, nor can the true process, or processes, ever 

 be discovered in library or cloister, nor evolved out of our own 

 inner consciousness. The recognition of this is a great step 

 forward. The true method, or methods, of organic evolution
