Faraday to Josiah John Guest   6 January 1819

Royal Institution | Jany 6th 1819

Sir

I think the sooner I am favoured with your specimens the better as it is always an object to secure as much time as possible for the consideration of any incidental or unexpected circumstances and though you will be aware from my last I cannot at present devote an undivided attention to them yet I should be sorry to lose the opportunities which periodical duties afford[.]

As it is evident you wish the subject to be considered in a very comprehensive way perhaps you will allow me the liberty of suggesting the propriety of enclosing in the packet you may send me such examples either of the products or the ores as may convey or illustrate any particular information to me though not intended to be analysed. In that case you will have the goodness to distinguish those to be analysed from those which are not that unnecessary expense & trouble my be spared. With respect to the intimation at the end of Your last it of course becomes my duty and shall be attended to conscientiously.

I am Sir | Very obediently Yours | M. Faraday

I shall be at liberty in June and if at that time you wish it should be glad to come to the works[.]

J.J. Guest Esq
