The Popular Science Monthly has had 

 few rivals and no equal in the educative 

 service it has done for the American peo- 

 ple A complete set of the volumes thus 

 far published is both a history of science 

 for the period covered and at the same time 

 a pretty complete cyclopedia of natural 

 science. There is nothing to fill its plac«, 

 and to cari-y it on is a benefaction to the 

 public— W. T. Harris, U. S. Commissioner 

 of Education.
