pared when he was an undergraduate, entitled,
Formula; for the Calculation of Jiailroad Earth-
irork and Average Haul (1876;, was at once
adopted as a text-book by six engineering scliools
in the United States. Other notable mathe-
matical works, originally published in Van Xos-
trand's Engineering Magazine (1879), include: A
Xeir Rule for Calculating the Contents of Land Mur-
reys; The Prismoidal Formula; A Xeto Centre of
Grarity Formula of General Applicability ; A Xeic
and General Moment of Inertia Formula, and ^4 Xeiv
Graphical Method for Finding the Centre of Gravity
of a Polygon. They have all been copied and are
to be found in standard works. The first of these
essays was received in late editions of Davies's,
Gillespie's and Jolinson's surveying, in Halsted"s
mensuration, and in Newcomb"s geometry and
trigonometry. This method superseded the
Pennsylvania or Rittenhouse method invented
by Thomas Burgh of Ireland about 1780, for the
discovery of which Mr. Burgh received froni
parliament 20,000 pounds sterling. Mr. Davis
published: Dynamics of the Sun (1891); Behavior of
the Atmosp?ieres of Gas and Vapor Generating Globes
in Celestial Space; and The Condensing Nebula
(1898).
