Dear Sir,
I beg to inform you of the completion of the experiment you were good enough to order – the dilute acid was not decomposed in the slightest degree – Please state if you would like the apparatus kept to show you when next you may be in town & have leisure to call [or] sent on?
Your obedt Servt
