July 10th 1860
I beg to acknowledge the receipt of a Bill on the ?? Bank for £5-6-6. I enclose herewith Messrs Ravelles’ receipt for 18/6 for Ozone Papers.
With regard to the fall of dew, I find that it can be measured though not of course with extreme accuracy by the Rain Gauge.
I am in the habit of adding all that is in the Rain Gauge whether dew or rain to the reading of the Evaporation. The result however is not strictly correct as I have no doubt a much larger quantity is deposited on the metal Rain Gauge than the water of the Evaporator.
I am Sir
Your obedient servant
