Cajori, in his "Hist of Math, in the U.S.," and the author of the 

 sketch of Newcomb in the New York Tribune, state that there was a 

 French Edition of Popular Astronomy. Professor Newcomb says this is 

 not the case. 



" It is unlike anything else, and will be of more use in circulating 

 a knowledge of astronomy than nine-tenths of the books which have 

 appeared on the subject of late years." — Sat. Rev.. XLV, p. 663. 



" We can cordially recommend Prof. Newcomb's ' Popular 

 Astronomy ' as the finest general treatise on the subject since Herschel 

 published his celebrated ' Outlines of Astronomy.' " — Knowledge, Vol. 

 I., p. 425. 



"... Most valuable book of its kind ever produced in this 

 country, if not in the world." — N.A.R., March and April, 1879.
