7 page printed catalogue of the mathematical works of Thomas Baker. According to David Gregory's own index this was "Printed by Mr Collins". John Collins was a well known register of scientific accomplishments and zealous correspondent with Gregory and his uncle James Gregory (the source of David's core maths collection). This catalogue was printed, with a proposal for producing all of Baker's works in full, under the aegis of the Royal Society, whose council approved the measure and agreed to do so, but never did. The catalogue appears in no indices to the Philosophical Transactions of the Royal Society. (Baker himself published elsewhere the "Geometrical Key, or Gate of Equations Unlocked", first item in the catalogue, in 1684.)
