All the above editions contain the celebrated ' Canon Triangulorum ', ' the first table of its kind published, which did 

 for sines and tangents what Briggs dii for natural numbers.' D. N. B. 



' The honour of the invention of Logarithms, next to the Lord of Merchiston, and our Mr. Briggs, belongeth to Master 

 Gunter, who exposed their numbers upon a straight line '. Oughtred. 



' Gunter was the first to use the terms cosine, cotangent and cosecant for the sine, tangent, and secant of the comple- 

 ment of an arc. To him are also due the invention of the surveying-chain, a quadrant, and a scale, and the first observa- 

 tion of the variation of the compass . The name of Gunter' s Scale, or Gunter' s Lines, is usually given to the 3 lines to be 

 seen on almost any sector, and marked N, S, T, meaning the lines of logarithmic numbers, of logarithmic sines, and of 

 logarithmic tangents. . . . Many rough problems in areas, heights, cubic contents, and other matters, may be performed 

 through the agency of Gunter's Scale '. 



' Gunter introduced a simple form of slide rule, or as he called it, a ' line of numbers ' which provided a mechanical 

 method for finding the product of two numbers.' IT. W. R. Ball.
