Surveying Instruments.

A plain Table with Index and Sights, whereby the Draught or Plan is taken on the Spot.
Plain Tables, improved with an Index of a peculiar make, whereby the Line of Sights in viewing is always over the Center of the Table, which also is readily set over the Station Hole, the Station Lines are likewise drawn parallel to those measured on the Land, and the Table is set horizontal by a Spirit Level.
Theodolites, for measuring Angles, Distances, Altitudes, &c. Those Instruments are made various Ways; some being more simple and portable; others more accurate and expeditious.
The Plain Theodolites, which consists of four plain Sights, two fastened to the Limb, and two on the Ends of the Index, with a Compass on the Index-Plate, divided into Degrees; and the Limb subdivided into Minutes by a Nonius's Division; the Whole upon a Ball and Socket, and that placed upon a three-legg'd Staff.
Theodolites of the latest Improvements, by T. Heath. This Instrument has a Spirit Level affixed to the Telescope, and another, at Right Angles thereto in the Box; by Means of which cross Levels, and the Help of four Screws playing between two Plates in the Brass Head of the Staff, the Plate, or Limb of the Instrument, is readily brought to a true horizontal Situation; the Telescope, with cross Hairs therein, turns on an Arch, fixed to the Index perpendicular to the Plate of the Instrument; the Arch is of the same Radius as the Plate, and the Telescope may be elevated or depressed thereon quite to a Quadrant, or 90 Degrees: On this Arch are graduated the Degrees of a Circle, which are numbered from the Vertex either Way, with 10, 20, &c. and are cut by an Index under the Telescope, divided after Vernier's, commonly called Nonius's Way, like those on the Limb of the Instrument: Within the Degrees are two Lines, numbered with 10, 20, &c. down to 100, and cut by the Edge of the Index, on the Right whereof is graved Elevation, and on the Left Depression. These Lines serve to shew the Altitude or Depression of any Object in 100th Parts of the Distance at which the Instrument is planted to take the Observation; and are useful in finding the Height of a Tree; in the measuring of Timber standing; as also to find the Altitudes of the several Parts of a Building, in drawing the Perspective Appearance thereof.

Notes on Heath and Wing

Catalogue of Instruments

Notes and book transcription by David Manthey. Notes copyright © 2002.


This catalogue of instruments by Heath and Wing was originally published in 1765 in the back of The Practical Surveyor by John Hammond and Samuel Warner. It comprised the final signature of the book, consisting of 16 pages (the last two of which were blank).

There are at least two books of the title The Practical Surveyor, both of which were first published in 1725. Samuel Wyld's book of this name featured instruments by the famous Jonathan Sisson, who invented the wye level as well as other tools still in use today. Hammond's book started off as a brief guide to surveying, but later was expanded and modified to compete with Wyld's book.

T. Heath was selling technical books and instruments at least as early as 1725. Wing appears to have been a junior partner, as his name doesn't appear on publications in 1750, but does on those of 1753. Heath and Wing were in business at least through 1769.


This catalogue was originally printed with very large outside and bottom margins. It seems likely that Heath and Wing had this catalogue bound into any book they sold. A set of these catalogues would have been printed on large paper and folded into a standard 16 page signature. This signature could be easily sewn into any book as the last signature, then trimmed to the book size and bound as part of the book. This would allow it to be added to any book that was at least 7 ¾ x 4 ¼ inches in size, while still working for books that were upward of 10 x 7 inches (based on the standard octavo sheet size).

This reprint [the PDF version] is nearly identical to the original. It has been re-typeset using a font that is close to an exact match. The pagination is the same as the original, though a few words have shifted one line in location, and the end words at the bottom of each page are not always the same. The original spelling and typesetting errors have been maintained.

The margins were selected to be consistent with a book with the size text that was used. In the original printing, the page size, outside margin, and bottom margin were larger.
