SCIENTIFIC INTELLIGENCE, AND NOTICES OF SUBJECTS 
CONNECTED WITH SCIENCE, 
I. Lectures. 
Mr. Bakewell will deliver a series of Lessons in Geology at the 
Argyle Rooms, to commence the middle of the present month 
(May). The mode of instruction by lessons in a science presenting 
new and interesting objects of inquiry at every step will be found to 
possess many advantages, admitting questions and explanations 
which are precluded by the formality of public lectures. 
Dr. Clutterbuck will begin his Summer Course of Lectures on 
the Theory and Practice of Physic, Materia Medica, and Chemistry, 
on Monday, June 2, at ten o'clock in the morning, at his 
house, No. 1, in the Crescent, New Bridge-street, Blackfriars.

The character of this period during the former part was windy 
and changeable, with slight showers at intervals. From the 7th to 
the 23d the weather was cold and wet, with frequent showers of 
snow ; and on the 16th it fell in considerable quantity, followed 
by rain, and a violent gale from the south. On the 23d a rapid 
increase of temperature and pressure took place, and the weather 
to the close was as calm and mild in these parts as it often is at the 
beginning of May. 
The barometer has again been very low. The minimum occurred 
on the 20th, during a heavy storm of wind and rain from the S, 
For six preceding days the wind had blown steadily from that 
quarter, and the column was uniformly under 29:00; but on the 
SIst it indicated its maximum of elevation. 
The variations towards the beginning of the month were again 
considerable, and the column throughout was in continual fluctua- 
tion.
