August 7th 1858
I beg to call your attention to my letter of June 10th of which no notice has been taken by you except the discontinuance of all the 9pm observations which has the effect of rendering your returns still more imperfect than before.
The Barometer readings are quite useless; those at 3pm being generally a copy of the 9am previous.
I have now to request that you will discontinue the observations which as they are now made are quite valueless unless you can give me any reason to believe that they will be taken with greater accuracy in future.
I must also beg you to reply to this letter at your earliest convenience.
I am Sir
Your obedient servant
