Lugodini, Jod. a Colsier, 1617 

 A work of great importance in geodesy, in which the author tlrst laid down the prin'fipies now generally accepted for 



determining the length of the arc of a meridian from the measurement of any base line. This discovery was again claimed 



by Pothonot in 1730 as an original one. 



The work contains also a valuable account of older works on geodesy. 



Snellius is also the discoverer of the law of refraction (given afterwards in its present form by Descartes), and th&- 



originator of the term loxodromic curve.
