Virginia, 102. The comparison between birth- 
place and present location is equally interest- 
ing, illustrating as it does the westward drift, 
the concentration in States of large cities, and 
the disadvantage of foreign birth in the race 
for accomplishment. No occasion for 
criticising the book appears, though it may be 
suggested that its convenience might be in- 
creased in future editions by printing both the 
ordinary form of writing the name and the 
full forename in parentheses, after the manner 
adopted (but afterward abandoned on pecuniary 
grounds) by the Joint Commission of the Scien- 
tific Societies of Washington, thus: Gordon, 
Professor J. C. (Joseph Claybaugh). But even 
without this refinement, the book is admirably 
complete and convenient.

DISCUSSION AND CORRESPONDENCE. 
ANAGLYPHS AND STEREOSCOPIC PROJECTION. 
AFTER an enthusiastic period some twenty 
odd years ago the interest in stereoscopic views 
suffered a reaction. The interest has been 
lately reawakened in many ways. In SCIENCE 
Professor Jastrow has already discussed some 
stereoscopic methods; in ScIENCE for July 14th 
of this year Mrs. C. Ladd Franklin makes 
special mention of pictures printed in two 
colors and urges the adoption of a method of 
stereoscopic projection. The following account 
may, perchance, contain some minor bits of 
information not already well known.
