                                Diagrams in John Collins's solution to the problem proposed by Richard Towneley of measuring the distance of three objects from one position. This was read to the Royal Society on 20 January 1670 and printed in Philosophical Transactions vol. 6, no. 69.

                                The distances of three objects in the same Plane being given as ABC, the Angles made at a fourth place in the same Plane, as at S, are observedl The Distances from the Place of Observation to the respective Objects are required.

                                At the meeting of the Royal Society on 20 January 1670, ‘Mr. Collins’s solution of the problem for measuring the distances of three objects from one station was read, approved of, as to its  truth (though its practicableness at sea was doubted) and ordered to be registered’ (Birch 2:416).
