REroRT OF 
of the longitude of the Observatory, which is assumed from the 
position of York Minster, as given in the Trigonometrical 
Survey of Great Britain, to be nearly 4m. 19s. W. of Green¬

The Council has seen with satisfaction the completion 
of the Second Volume of the Illustrations of the Geology 
of Yorkshire, on which Professor Phillips has been so long

the success which has attended the Evening Scientific Meet¬ 
ings, during the past year is a gratifying proof that the spirit 
of mutual improvement is more than ever active in our body, 
and by its unobtrusive operation preparing the way for 
a more extended communication of knowledge among the 
Members. 
The Society is thus found to be in a good position in all that 
relates to its scientific reputation; the statement of the Trea¬ 
surer, appended to this Report, will shew that but for the 
taking into the account, by direction of the last Annual 
Meeting, the deficiency of the subscription for the Observa¬ 
tory (P130.) the amount of the general debt would have been 
reduced <P40. 
The Council would however not fulfil the duty it owes to 
the Society, did it not declare that there yet remain some 
further expenses to be incurred in the Library for books of re¬ 
ference, and in the IMuseum for cabinets to hold Insects, Plants, 
Minerals, and Geological specimens, which can be ill met if
