Summary:

Cites various celestial appearances as a basis for concluding that the Milky Way takes the form, not of a disk or ring, but of a series of convolutions. Urges that the nebulae form part of the Milky Way rather than being separate universes, as many had suggested. Asks JH to critique these ideas.

Summary:

Elaborates on his hypothesis that all forms of nebulae are part of the Milky Way and on his 'twisted-stream theory' of the Milky Way's structure. Favors view that dark matter is relatively common in space and that it extinguishes light from distant objects. Proposes method of measuring stellar diameters.

Summary:

Accepts JH's objection to his method of measuring stellar diameters. Quotes an argument he had published suggesting the existence of a hierarchy of systems in an infinite universe. Discusses his studies of the relation of proper motions to the sun's motion. Asks JH's permission to publish JH's idea that some nebulae may be 'miniature' of the Milky Way.

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.
