Last week I posted a picture of Hadley’s Spirit Level applied to a Quadrant (I called it a Sextant by mistake). I have now transcribed the text of his Paper describing how the device was made and how it performed. The attached Word file should be read in conjunction with my last post (NavList 9513).
Clive.
