“ Post-Darwinian Questions,” the second part of the late Prof. George 
J. Romanes work, “ Darwin, and After Darwin,” is announced 
for publication by the Open Court Publishing Company, of Chicago, on 
October 15th next. With the exception of the concluding chapters,- 
the present volume was ready for publication over two years ago, but 
the severe and protracted illness of Professor Romanes prevented its 
speedy completion. On his death, in 1894, the manuscript was placed 
in the hands of his friend, Prof. C. Lloyd Morgan, the distinguished 
biologist and Principal of University College, Bristol, England, who 
has successfully edited the work. This volume, with the first on “ The 
Darwinian Theory,” and the booklet on “ Weismannism,” constitutes, 
in the opinion of all competent critics, the most complete and authori- 
tative general treatise on evolution in the English language. (Pages, 
334. Price, $1.50.) 
The same publishing house has also recently issued a second edition 
of Professor Romanes “ Thoughts on Religion,” declared, by a promi- 
nent writer in the Chicago Tribune, to be “ one of the most valuable 
books the century has produced.” (Pages, 184. Price, $1.25.) 
The Open Court Publishing Co., of Chicago, will issue, late in Octo- 
ber, one of the most important books on the theory of evolution which 
America, perhaps, has yet produced. Its author is Prof. E. D. Cope, 
of Philadelphia, a well-known representative of the Neo-Lamarckian 
school of America, and represents the opposite extreme to Weismann- 
ism in evolution. In this book, which is entitled ‘‘ The Primary Factors 
of Organic Evolution,” Professor Cope will seek to show, principally 
by an examination of the paleontological records (in which he has done 
his main original work), and secondarily by a review of the general 
results of embryology and comparative anatomy, what the efficient 
causes are that are concerned in the progressive development and per-
