These notes written by James Dinwiddie focus on matter. The notes are split into three sections; the first deals with the properties of matter including various propositions. The second discusses the perserverance of matter or what happens when forces are applied. The final section deals with the powers of matter and involves inertia and resistance.

These notes written by James Dinwiddie examine a number of topics in physics including light, motion, matter, hydraulics, and hydrostatics as well as a treatise on Nature from the points of view of philosophy, art, and theology.
This introductory lecture written by James Dinwiddie discusses natural philosophy. Dinwiddie draws on past philosophers including Rene Descartes, Plato, and John Locke to describe Nature and man's relationship with her.
These notes written by James Dinwiddie focus on topics in mechanics such as gravity, momentum, compound engines, and Ferguson's machine as well as matter, magnetism, electric shock, and capillary action in the introductory section.
James Dinwiddie wrote this introductory lecture on January 19, 1792. He discusses knowledge, existence, and sensation and quotes Rene Descartes (Cogito ergo sum).

These notes written by James Dinwiddie outline a lecture on astronomy. He discusses the various planets and their motion as well as their various measurements (diameter, distance from the sun).
These lecture notes written by James Dinwiddie in 1787 (?) discuss the study of pneumatics. He notes its connection with air and the atmosphere. Dinwiddie records several experiments involving barometers, fountains, and pumps.
In this series of notes written by James Dinwiddie, he discusses various natural philosophers' theories of the earth. He includes theories from Burnet, Woodward, Whiston, and Buffon.
These lecture notes written by James Dinwiddie discuss theories related to volcanic eruptions. Dinwiddie also mentions physical structures of the volcano and historical dates for volcanic eruptions.
These notes written by James Dinwiddie outline twenty lectures on topics in physics including motion, gravity, force, and acceleration. The notes also touch on natural theology with respect to knowledge and creation.
These point form notes were taken by James Dinwiddie at a lecture on Wednesday, June 11, 1783. The notes cover a range of topics in chemistry and physics including Boschovich's Theory, chemical mixtures, evaporation, and magnetic curves.
These notes written by James Dinwiddie contain sections of notes on various topics including the history of medicine, chemistry, electricity, proof of repulsions, and mathematics.
These notes written by James Dinwiddie examine a number of topics including ballistics, physics, and astronomy. Dinwiddie discusses the retrograde motion of Mars, Mercury, Venus, Saturn, and Jupiter. He also discusses motion with reference to military weapons mentioning air resistance, projectiles, and velocity.
This series of lecture notes by James Dinwiddie in 1792 (?) references several subjects including mathematics, natural philosophy, Plato, Epicurius, the motion of the Earth, David Hume, and "W. Harrington". The file consists of 29 pages of lecture notes.
These notes written by James Dinwiddie from April to May, 1811 are from a series of geology lectures by H. Davy. The notes cover the composition of earth and minerals as well as various experiments.
These notes written by James Dinwiddie on July 30, 1811 are from a lecture on hydrostatics given by Mr. D.F. Walker. The notes mention the hydrostatic paradox and Tantalus' cup as well as flotation experiments.
File contains a letter from Mary Dobie to James Dinwiddie. In the letter, Dobie thanks Dinwiddie for a Carnelian seal ring he sent to her as a gift. The letter was likely written sometime in the 1810s.
This file contains a one page newspaper clipping from a Calcutta newspaper. The clipping is a reprinted editorial letter from Joseph Priestley denouncing the new theories of chemistry.
