456 SUMMARY OF PROGRESS IN ANTHROPOLOGY IN 1891. 
A remarkable series of lucky finds were made on the Hopewell farm, 
near Chillicothe, Ross County, Ohio, by Mr. Warren K. Moorhead, di- 
rector of the World’s Fair archeological expedition at that point. Not 
only were new forms of objects discovered, but old forms were collected 
by thousands. The exciting part of the exploration was the finding 
of hundreds of copper objects, many of them of such uniform thinness 
as to raise the question of their European origin. 
The Drexel Institute, founded in Philadelphia by the liberality of Mr. 
Anthony J. Drexel, will be devoted to the encouragement of technical 
industries. The museum will be administered on the plan of South 
Kensington. 
Before the Tennessee Historical Society the Hon. Gates P. Thurston 
delivered a short course of lectures on the archeology of Tennessee, 
SOCIOLOGY. 
Economie science as a branch of sociology is the all-absorbing study 
of the time. There is not space to enumerate the separate books and 
papers on this subject, but every reader should know the general re- 
sources of the study. Section F, British Association, Economie Sei-

Among the political leaders of France, as well as in the Société 
WV Anthropologie, no other question seems to be of such importance as 
that of the decrease in natality throughout the Republic. M. Chervin 
sums up the results of an inquiry in the department of Loir-et-Garonne 
in the Bulletin de la Société W@W Anthropologie (4 ser., 1, 42-78). There 
results the demonstration that in this rich department it is the most 
wealthy that have the smallest number of children, and in the most 
thriving part of the department the average of children to a family is 
one. Among the causes of this paucity M. Chervin finds that the well- 
to-do peasant and farmer wills it to be so, and he believes that no leg- 
islation will effect a radical change. Believing that quality and that 
early deaths become a potent factor in the decline of population, to M. 
Chervin the saving and perfecting of lives already created is the feasi- 
ble method of strengthening the population. Assistance and hygiene 
are the practical methods of relief. 
M. Bertillon (id., 366-385), regarding the terrible dangers to which 
the phenomenally low natality in France exposes her, and believing 
that the evils of alcoholism, tobacco, and syphilis have only a subsidiary 
influence, makes the following statement: ‘‘ That which renders the 
natality of France so feeble is the voluntary sterility of families hay- 
ing some property. Such families are exceptionally numerous in 
France. They know that the sure way to keep their property is to 
have only one child, and a sure way to lose it is to have more than two. 
One way, therefore, to save France is to remove the cause of feeble na- 
tality and to make it more desirable in the way of relief from taxation 
and increased security of property to have three children than one.” In
