Faraday to Henry Ellis   28 September 1853

Royal Institution | 28 Septr. 1853

My dear Sir Henry

I shall this day, personally, return the crystal to Mr. Waterhouse¹ and beg you will have the goodness to express my sincere thanks to the Trustees of the British Museum for the favour granted me. I have optically examined the crystal, and find it just what I wanted; but from the delays which occurred, so much of the sunny weather has passed by that I have little hope now of any fit for my purpose this year. If however between this time and next Summer I am encouraged by results with other crystals I may probably make application then for a second loan of the specimen[.]

I am | My dear Sir Henry | Your Very Obliged Servant | M. Faraday

Sir Henry Ellis | &c &c &c
