“ Observations of Dr. Klein’s new Lunar Crater near 
Hyginus, made at the Observatory, Birkdale,” by Joseph 
Baxendell, F.R.A.S. 
In consequence of the conflicting statements which had 
been made with reference to the object in the moon near 
Hyginus discovered by Dr. Klein on the 19 th of May, 1877, 
which he believed to be a new crater; and some observers 
having doubted its existence, I took advantage of the fine 
night of the 2nd of November, 1878, to turn the telescope 
on the moon, which was then in a phase favourable for the 
observation of the region of Hyginus, and having Dr. Klein’s 
drawing to refer to, I at once saw the object which has been 
made the subject of so much discussion and dispute. It 
appeared at 6h. 15m. G.M.T. as a round and very dark spot, 
and was slightly less black than the shadow in Triesnecker. 
With powers 180 and 260 its diameter was estimated to be 
about two-thirds that of the crater marked by Dr. Klein 
Triesnecker d (Beer and Msedler’s Hyginus a); and in 
moments of best vision I received the impression of an 
extremely delicate line of light on its eastern border. The
