Expanded and renamed
This: "''Pratt was the author of Mathematical Principles of Mechanical Philosophy (1836), subsequently expanded and renamed On Attractions, Laplace's Functions and the Figure of the Earth (1860, 1861, and 1865). The final edition is a treatise of some 162 pages. The fundamental goal of the text is to supply an answer to the question as to whether the earth acquired its present form from originally being in a fluid state." can't be correct. The original work is more than 600 pages, and the matter of the figure of the earth is only a small part of it. Perhaps it should say an excerpt was republished under the title...? catslash (talk) 22:34, 10 July 2021 (UTC)

Here is On Attractions, Laplace's Functions and the Figure of the Earth at archive.org. In the preface, Pratt explains the relationship of the two works. catslash (talk) 22:20, 27 July 2021 (UTC)

The book (1865 ed. which is a complete revision of all earlier works) is divided into two parts. The first deals with attractions at a point from ever closer approximations to the form of the Earth. - The second part which starts at page 66, deals with calculating the figure of the Earth. A single self contained volume in two parts.
