Author admits that in the present state of the inquiry he is 
not prepared to offer any theoretical explanation of this 
remarkable phenomenon. His observations have been made 
without reference to any particular theoretical views ; and, at 
present, he does not offer the conclusions given in his Paper 
as anything more than the first results of an attempt to 
pursue, without reference to any theory, a systematic examina- 
tion of the phenomena of the solar spots. 
Extracts from the Author’s journal of observations were 
given to illustrate the several points to which he has drawn 
attention. 
In the discussion which followed, Mr. Williamson 
exhibited diagrams shewing the results of his observations 
upon the sun, up to and inclusive of those made on the 13th 
instant. 
Mr. Heelis also produced, for the inspection of the 
members, a copy of the “ Selenographia” of Hevelius, 
including his observations upon the solar spots. 
Messrs. Sidebotham and Heelis also stated that the 
conclusions drawn by Mr. Baxendell were pqrtly confirmed 
by their own observations. 
A Paper was read by Mr. Thomas Garrick, “ On the 
Relation which appears to subsist between Orbit Distances 
and Orbit Inclinations, when the latter are referred to the 
Solar Equator as a fundamental plane.” 
Taking orbits of each kind in groups successively receding 
from the sun, there is — with the exception of the planetoids — 
a progressive increase in the mean inclination of each group, 
as under : —
