“It is certainly a useful and convenient volume, and readable too, if we judge correctly of the degree of accuracy of the whole by critical examination of those cases in which our own knowledge enables us to form an opinion.... In general, it seems to us that the handy volume is specially to be commended for setting in just historical perspective many of the earlier scientists who are neither very generally nor very well known.”—New York Evening Post.

“One of the most valuable books which we have received.”—Boston Advertiser.
“A book of no little educational value.... An extremely valuable work of reference.”—Boston Beacon.

“A biographical history of science in America, noteworthy for its completeness and scope.... All of the sketches are excellently prepared and unusually interesting.”—Chicago Record.
“One of the most valuable contributions to American literature recently made.... The pleasing style in which these sketches are written, the plans taken to secure accuracy, and the information conveyed, combine to give them great value and interest. No better or more inspiring reading could be placed in the hands of an intelligent and aspiring young man.”—New York Christian Work.
“A book whose interest and value are not for to-day or to-morrow, but for indefinite time.”—Rochester Herald.

“Full of interesting and valuable matter.”—The Churchman.
