Treatise on Natural Philosophy was an 1867 text book by William Thomson (later Lord Kelvin) and Peter Guthrie Tait, published by Oxford University Press.
The Treatise was often referred to as T and T ', as explained by Alexander Macfarlane:
The first volume was received by an enthusiastic review in Saturday Review:
The Treatise was also reviewed as Elements of Natural Philosophy (1873).
Thomson & Tait's Treatise on Natural Philosophy was reviewed by J. C. Maxwell in Nature of 3 July 1879 indicating the importance given to kinematics: "The guiding idea … is that geometry itself is part of the science of motion."
In 1892 Karl Pearson noted that T and T ' perpetuated a "subjectivity of force" that originated with Newton.
In 1902 Alexander Macfarlane ascribed much of the inspiration of the book to William Rankine's 1865 paper "Outlines of the Science of Energetics":
