On the Climate of North Northumberland as Regards its Fitness for Astronomical Observations

Abstract

I HAVE looked again at my observations (p. 317), and can assure Mr. Joseph Lingwood of their entire accuracy. For astronomical purposes the sky is “completely overcast” when not a star is visible. As the observations in question referred to the year 1881, I do not see what the “weather since taken” has to do with the question, unless it be contended that the weather in January, 1881, was precisely similar to the weather in January of the present year. As a general rule the observations would refer to a later hour than 6 p.m.
