The point of last contact is •I34 j- from 
wards the East. 
The time mentioned in the preceding account is in all cases 
Greenwich mean time. 
According to the civil method of computing time, the 
eclipse will commence at Manchester, March 15d. llh. 41m. 
2s. a.m. — the greatest phase 12h. 59m. 3s., and will end 2h. 
15m. 33s. p.m. Greenwich mean time. 
For any place, not far distant from Manchester, whose 
geocentric North latitude is I, and East longitude is A, the 
mean Greenwich time t of beginning may be computed by 
the formulae, 
cos T21625 — [0T52151 sin l-\- ro-056011 cos I cos(A — 
98° 39'-4) 
t = 23h. 56m. 25s [3*67069] sin w + [3*72622] sin I —

In the course of the conversation which followed the 
reading of the paper, a general regret was expressed, that 
although efforts to establish an astronomical observatory had 
from time to time been made by members of the society and 
others interested in the cultivation of science, they had not 
met with that encouragement on the part of a wealthy and 
intelligent community and its authorities which might have 
been anticipated. It was doubted whether there was any
