A thermometer placed on a level with the basin of my portable 
barometer, was all the morning 11° lower than the one attached 
to the top of the tube. I was induced to pay particular atten- 
tion to this observation, from seeing it mentioned in your Philoso- 
phical Magazine and Journal for last June, p.468, that two 
thermometers, one suspended on each side and nearly in the 
centre of the barometrical tube, were 4 to 5° lower than the 
attached thermometer,” which I thought was an extraordinary 
discrepancy in so short a space downwards. I have frequently 
tried this experiment within the last few months, but have never 
seen the thermometer placed in the middle of the tube, or on a 
level with the basin of my barometer, either in wet or dry weather, 
lower than 14°, notwithstanding the accurate adjustment, and 
coincidence of the thermometers when placed together. Ge- 
nerally it is about 1° lower when placed level with the basin, in 
an airy room. j 
Since the 14th ultimo, 5.875 inches of rain have fallen here, 
making the quantity for this year up to the present time 32-365 
inches, that is 6-615 inches more than fell in the neighbourhood 
last year. 
The evaporation this year is comparatively small, being up- 
wards of 12 inches less than the quantity of rain ; therefore, the 
ground must be in a very moist state to a good depth, 
The planet Venus was seen here with the naked eye this, and 
on the afternoon of the 5th instant, when on or near the meri- 
dian; and will become more visible in the open day, as she ad- 
vances to her greatest elongation,
