O'BRIEN (Matthew). Mathematical Tracts, Part I. On Laplace's Coefficients, The Figure Of The Earth; The Motion Of A Rigid Body About Its Center Of Gravity And Precession And Nutation.1840

Cambridge: printed at the University Press, for J. & J. J. Deighton, First edition, part I [all published], viii, 86pp., with half-title, title page with cont. note stating "shortly will be published Part II. Mathl Theory Electricity...", disbound. "The subjects treated of in the following Tracts are, Laplace's Coefficients; the Investigation of the Figure of the Earth on the Hypothesis of its Original Fluidity; the Equations of Motion of a Rigid Body about its Center of Gravity; and the Application of these Equations to the case of the Earth. The first of these subjects should be familiar to every Mathematical Student, both for its own sake, and also on account of the many branches of Physical Science to which it is applicable. The second subject is extremely interesting as a physical theory, bearing upon the original state of the Earth and of the planetary bodies; it is also well worthy of attention on account of the important and extensive observations which have been made in order to verify it."—Preface.
