While discussing this subject, allow me, gentlemen, to advert to an article in your contemporary of Friday last. In the "Echoes of the Month," by an Old Photographer, the writer thinks that the advantages I pointed out as likely to accrue from a union of the societies are a "pleasant prospect that will not bear the test of figures." It is a fact that "figures" are subject to the rules of addition as well as of subtraction, and I wish to show by figures that my ideas are not so impracticable as he imagines. In addition to the eight guineas a year paid by the North and South London Photographic Societies for rent, I notice in the report of the London Photographic Society, published last month, two items in the "liabilities" which are worth considering. One is "King's College, rent and refreshment, £42 4s. 6d.," which, I presume, is for one year. The other is "King's College _soirée_ account, £20 15s. 6d.," part of which is undoubtedly for rent of rooms on that occasion. Now there is a clear showing of over £50 12s. 6d. paid in one year by the three societies for rent and refreshment, the latter not being absolutely necessary. I may be mistaken in my estimate of the value of central property; but I do think a sum exceeding £50 is sufficient to secure a room or chambers large enough for the purposes of meeting, and keeping a library, &c.; or, if not, would it not be worth while making a strain to pay a little more so as to secure the accommodation required? If the Coventry Street experiment were a failure from apathy or other causes, that is no proof that another attempt made by a more numerous, wealthy, and energetic body would also be abortive. In sea phraseology, "the old ship has made a long leg to-day!" but I hope, gentlemen, you will not grudge the space required for the full and careful consideration of this subject. The "developing dish" and the ordinary _modus operandi_ of photography can well afford to stand aside for awhile to have this question discussed to the end. I have not said all I can on the amalgamation project, and may return to it again with your kind permission, if necessary.--I am, yours, &c.,

The Evolution of Photography — Part 172

The brief and all but impromptu Exhibition of the Photographic Society, recently held in the rooms of the Architectural Society, 9, Conduit Street, Regent Street, where the Society's meetings are to be held in future, was one of the pleasantest and most useful expositions in connection with photography that has been consummated for many years. In the first place the idea of an exhibition evening free from the formalities of a _soirée_ was a happy one; the _locale_ was happily chosen; and the whole arrangements most happily successful. Everybody seemed to be pleased; cordial expressions of agreeable surprise were freely exchanged; and there were abundance and variety enough of pictorial display to satisfy the most fastidious visitor.
