My dear Sir

Adverting to your inspection in company with the Deputy Master¹, of the Lights exhibited at Major Fitzmaurice, on the Evening of Monday last²,- I am directed to request you will state for the information of the Elder Brethren, whether you consider that the means by which the Light is produced are such as to render it applicable to Light House purposes,- or what preliminary data you would require for the purpose of forming an opinion on the Subject.

I remain | My dear Sir | Yours very Truly | P.H. Berthon
