find the mother more impregnated with the blood of the paternal 

 house? And if so, does this impregnation seriously tend to make 

 the children favor the family that gives them the name ? Is the 

 fact of parental influences ^ the influences here alluded to being 

 those suggested by Mr. Williams, sympathy or antipathy for peo- 

 ple frequently seen — thoroughly established ? In a love-match is 

 the face of the father more commonly reproduced ? If there are 

 reversions to a primitive type, what is the type — one lying on the 

 maternal or the paternal side ? 



Do family portraits show a uniformity? If they do, is not the 

 question settled ? How, then, can the fact that family portraits 

 show a uniformity — that being the point in question — be cited 

 to prove the point in question, that family portraits do, or do not, 

 show a uniformity ? J. C. Dana.

AMONG THE PUBLISHERS. 



Thomas Whittaker has just published " The Story of the Dis- 

 covery of the New World," by Frederick Saunders of the Astor 

 Library, illustrated by C. A. Bobbett. 



— A. C. McClurg & Co. announce a volume entitled "Direct 

 Legislation by the People," by Nathan Cree. The author gives 

 a brief review of direct government from the earliest times, and 

 of the rise and development of popular representation. He then 

 considers the advantages of combining direct popular legislation 

 with representative institutions, in which direction, he believes, 

 lies emancipation from political corruption. In this connection he 

 examines two remarkable features of the Swiss Government, viz., 

 the Referendum and the Popular Initiative. The author's stand- 

 point is said to be conservative.

 from Lightning. 



The Lightning Dispeller. 



Price, $20 to $30.— According to size, 



The Patent Lightning Dispeller is a conduc- 

 tor specially designed to dissipate the energy 

 of a lightning discharge, — to prevent its 

 doing harm,— placing something in its path 

 upon which its capacity for causing damage 

 may be expended. 



No recorded case of lightning stroke has 

 yet been cited against the principle of the 

 Dispeller. So far as known, the dissipation 

 of a conductor has invariably protected under 

 the conditions employed.
