LIBRARY OF SCIENCE FOR THE 

 WORKERS. 



This new series of the latest and best writings 

 in popular science in simple and popular style 

 and at the low price of fifty cents a volume, has 

 met with a success far beyond what we had 

 counted upon, and we shall without doubt make 

 rapid additions to this library in the near future. 

 Meanwhile we recommend the books already is- 

 sued and announced as indispensable to an 

 understanding of the latest tendencies in modern 

 science for those who have not the leisure for 

 years of study. 



BOELSCHE, Wilhelm. The Evolution of 

 Man. Translated by Ernest Untermann. 

 Cloth, 50 cents. 



This popular work, already in its sixth thou- 

 sand, is by no means a mere summary of Dar- 

 win's ''Descent of Man;" it is rather a summary 

 of the work accomplished by a whole generation 

 of scientists along the lines opened up by Darwin. 

 He was too genuine a man of science to claim 

 that a theory was proved before the proofs were 

 ready, and those who know the evolution theory 

 only from the cheap reprints of his great works 

 are sometimes confused by the noisy claims of 

 theologians to the effect that evolution is still an 

 unproved theory. This little book gives the proof 

 in form as readable as it is convincing." The 

 "missing links" so much talked of a generation 

 ago have been found, and their pictures are in 

 this book.
