**[1]**The article misleads in baldly referring to Babbage as ``Lucasian professor of mathematics at Cambridge,'' when he held this title for only the eleven years 1828-39, but delivered no lectures.**[2]**For the first published account of the application of a commercial calculating machine to mechanical integration see L. J. Comrie, ``On the application of the Brunsviga-Dupla calculating machine to double summation with finite differences,'' R. Astr. So.,*Mo. Notices*, v. 88 1928, p. 447-459. The Brunsviga-Dupla has since been superseded by the Brunsviga 20, the Burroughs, and the National. See also L. J. Comrie, (a) ``The application of the Brunsviga Twin 13*Z*calculating machine to the Hartmann formula for the reduction of prismatic spectograms,''*The Observatory*, v. 60, 1937, p. 70-73; (b)*On the Application of the Brunsviga Twin 13Z Calculating Machine to Artillery Survey*, London, Scientific Computing Service, 1938. This latter describes new and original methods of solving problems arising in surveys where rectangular coordinates are used.**[3]**L. J.

A new machine for solving differential equations,'' Franklin Inst.,*Jn.*, v. 212, 1931, p. 447-488, well documented. The original machine has been greatly extended and improved. The best simple account of the differential analyzer was by D. R. Hartree in ``The mechanical integration of differential equations,"*Math. Gazatte*, v. 22, 1938, p. 342-363, with five admirable plates, reproductions of photographs. There are also interesting ``References'' especially to ``Applications."**[8]**V.
