Dr. Burney’s Barometric Observations for June. 
To Dr. Tilloch. 
Gosport Observatory, June 11, 1821. 
Str, —Agreeably to the solicitation of John Farey, Esq., Sen., 
in your May Number [see this also page 22], I inclose my obser- 
vations on the State of the Barometer, &c. at the proposed hours, 
Mine is a wheel barometer, manufactured by a good workman 
in London. | find it sensibly affected in its oscillations by very 
small variations in the weight of the atmosphere; and as it ap- 
pears, by comparison with two others of a different construction, 
to be correct, these observations will be found the more valuable, 
particularly from the certainty of the real height of its basin above 
low-water mark, namely, 50 feet, and the proximity of its situation 
to the sea, the highest tides being nearly level with the ground- 
floor of my house. The attached Thermometer is correctly gra- 
duated to Fahrenheit’s scale: and the detached is a horizontal 
day and night self-registering Thermometer, which was also made 
in London. _I am, sir, your very obedient servant, 
Wiriiam Burney.

Dr. Burney’s Observations for July. 
To Dr. Tilloch.. July 9, 182). 
In sending you the observations on the state of the barometer, 
&c. on the other side, I think it necessary to remark that in these, 
as well as in the observations sent last month, the height of the 
Barometer was reduced to the temperature of 32°.
