IN issuing, under the name of the " INTERNATIONAL LIBRARY OF 

 SCIENCE AND FREETHOUGHT," a series of books of which the pre- 

 sent volume is the first, the FREETHOUGHT PUBLISHING COMPANY 

 desires to place at the service of English Freethought the 

 weapons wielded against superstition in foreign countries as well 

 as those forged in England itself. The writings of foreign 

 scientists are not as well known in England as their merit 

 deserves ; there are some valuable text-books such as those of 

 Gegenbaur and of Thome which have their place on the book- 

 shelf of the student; but the aim of the FREETHOUGHT PUBLISHING 

 COMPANY is to issue such works as will reach the general reader, 

 as well as the scientific student, and render Buchner, Hiickel 

 and others as well-known to the English public as are Huxley 

 and Darwin. German science is one of the glories of the world ; 

 it is time that it should lend in England that same aid to Free- 

 thought which in Germany has made every educated man a 

 Freethinker. France will contribute to this new library some of 

 the works of her leading sceptics ; and Italy, also, has furnished 

 help to Freethought which will not be forgotten. English and 

 American works will not be excluded, and it is hoped that a real 

 service will be done to progress by thus popularising in one 

 country the knowledge gained in many lands by the earnest 

 searchers after truth.
