Happy new year !
I had look for without success a pamphlet of AC Johnson : "How to find the longitude simultaneous with latitude at noon or other times", published in 1867.
It seem interresting to compae this book with others books writed by Johnson in the years 1880/90.
Can you help me ?
Thank you in advance
