October 27, 2010 #098 - Alvin G. Clarks Double Star Discoveries - Part 4

In the past few posts are mentioned the discoveries that the Clarks made while star testing new optics. As an occasional double star observer, I researched information on these discoveries. For those observers of double stars, here is a little observational data that I found in the "American Journal of Science and Arts"  Vol. XXV - Second Series - 1858 and Vol. XVII - Third Series - 1879. The first is written by the Rev. W. R. Dawes and the second S.W. Burnham, both well known astronomers.
