THE name Popular Sciknce News has been associated with the Boston Journal oJ 

 Cheviistri/, a paper long and favourably known in every State of the Union. The de- 

 sign of this most successful and useful journal has been to furnish in compact form, 

 and at a low price, the new facts in science, mechanics, invention, art, agriculture, and 

 viedicine, which it is so important should be widely disseminated among all reading people. 

 Its success is due to the fact that it presents in plain language, which all can under- 

 stand, scientific discoveries and principles which are useful to everyone, no matter what 

 may be their vocation or pursuit in life. It is an indispensable Family Journal, which 

 should be introduced to every fireside in the country. Dr. Nichols has edited this jour- 

 nal for a period of more than a sixth of a century, and every number contains many 

 pages of his instructive and pleasant contributions.
