Summary:

Reports finding, while preparing a star atlas, that bright stars appear to be very dense in a region associated with the Milky Way but centered on the greater Magellanic Cloud. Because of a coming lecture on stellar distribution, 'I ... am saturating myself with Herschelian astronomy.'

RS:HS 14.121
Summary:

Reports on his studies of stellar and nebular distributions, discussing especially whether the Magellanic Clouds show a relation to the Milky Way stars. Speculates on whether recent studies on meteors bear on stellar formation and change. Stresses need for statistical studies in stellar astronomy.

Summary:

Sends map from his new atlas. Reports finding a region rich in bright stars in the northern hemisphere but distinct from the Milky Way. States that in a Royal Institution lecture, he will claim that telescopes cannot reach the limits of the sidereal system and that it is far more complex than traditionally assumed.
