“ Besides wet plates I have had considerable acquaintance with collodio-albumed, using Pollitt’s plates, than which none better or more reliable could be had. Then there were in the days gone by Hill Norris’s plates, which for rapidity were probably equal to the bulk of the gelatine plates of to-day. My friend, Mr. Sampson, of Southport, having been very successful with these plates, Mr. Norris came from Birmingham wishing to know how they were developed; but Mr. Sampson, believing in the principle of 1 tit for tat,’ wished in return to be informed how they were prepared. Mr. Norris, not willing to impart his secret, went home no wiser than he came. I believe these plates were collodion and gelatine. On these plates, exposed many years since, the films have become very tender, though, of course, they were varnished. Query: How will gelatine stand the effects of time ? I think it will do so, but experienta docet. Then, also, there were the collodio-bromide plates of the past, which had their origin in this Society, and with these I was not very successful. I am referring to commercial plates, the best known of which were often covered over with spots, and were otherwise faulty from inherent defects in the film or preserva tive. Amateurs and other photographers of to-day may pride themselves on the fact that gelatine is in the ascendant; for there is no doubt that any plates which may now be purchased are infinitely more reliable than were other makes in the period to which I refer, with the further great advantage that they are not more than half the price. What a wonderful industry has sprung up in connection with the gelatine process! If it be true that the man is a benefactor to his race, who gets a blade of grass to grow where one has never grown before, it cannot be denied that Mr. Bennett has proved himself a benefactor of no mean order. “ A few years ago I was shown the album of an amateur at Warrington who worked exclusively the so-called “ coffee process,” and more beautiful views I have never seen. There was a richness, delicacy, and detail about them that was simply charming. I believe the coffee process was at one time used largely by the members of this Association, and I mention these views for the purpose of saying that good pictures can be produced by almost any process if one only determine to stick to it, and not to be led away by the voice of other charmers, ‘ charm they ever so wisely.’ If, when we get into the working of a process and succeed well with it, we are not satisfied to let well alone, but are always after the latest novelty, which is probably no improvement, the quality of our work will not be of a high standard—at any rate it will not be as good as it ought to be with those of us who have precious little time at our disposal. For others with ample leisure I would say—by all means experiment as much as you please, and possibly you may some day discover the Eldorado of photography which, I suppose, is the securing of natural colours. No doubt many of us have been novelty-seekers. For myself, at any rate, I may say I have tried numbers of new developers, each said of their originator to be of superior excellence. Some were strange compounds, and would not fix properly or filter clear, and were the opposite of improvement on old and well-established formula. “Then there is the matter of sulphite of soda in the developer. What difference of opinion about that! Indeed, in matters photographic opinions are diverse and often opposite. Some work in almost total darkness, while others use a fair amount of light in the dark room. Some recommend a good quantity of bromide in development, while others say none is needed. In these things each must decide for himself, and work accordingly. “ Next to these differences of ideas rapidity seems to be the order of the day ; for are we not offered plates up to sixty times the rapidity of wet ones ? For myself I should like to see gelatino-bromo-iodide plates in the market certainly not more rapid than wet ones, as I do not believe there is any advantage in this excessive rapidity for landscape work. For instantaneous pictures, of course, plates cannot be too rapid. For amateurs commencing the practice of the art a slow plate is most desirable, as there would be greater latitude in exposure and more certainty of obtaining a dense and vigorous negative. “ If at the next soiree of the associated societies we could get together specimens of the photographic art from its commence ment until now they would be very interesting and instructive. “ The matter of the question-box has several times been men tioned, and, as we are having so large an increase of new members, it would be well if those seeking instruction on any point would make known their needs through the box, when, no doubt, they would get the information desired. “ In concluding these rambling remarks, I would express the hope that this year may be the most successful the Society has known. May there be a healthy stimulus and emulation among us ; and may the weather so favour us that, when on photo graphic pleasure bent, we may come back laden with numbers of good negatives, which we shall have pleasure in submitting to our fellow-members, or reserving for the competition subjects, or the presentation prints.” The proof of the presentation print—an enlargement from a negative by Mr. J. H. T. Ellerbeck—was exhibited and approved by the Society. Mr. Ellerbeck also produced proofs of the pic tures printed in platinotype, and these were preferred by many to the carbon prints. Mr. Ellerbeck read a paper on a recent photographic tour across country in Prussia, and illustrated the same by about 100 views taken during his tour (see page 68). In answer to in quiries he stated that the stop used with a lens of thirteen inches’ focus was one-eighth of an inch, which accounted for the extreme —almost microscopical—sharpness which characterised the prints. The usefulness of the actinometers was proved by the evidently correct exposure in all cases, even in the most difficult subjects. Mr. Potter passed round a large number of very excellent photographs taken by him during his recent stay in South America. Dr. Kenyon exhibited an improved mode of using the mag nesium light, by burning the wire in an ordinary bottle containing pure oxygen. Mr. H. Cussons sent, through the Hon. Secretary, his usual kindly gift of almanacs for 1883. Mr. K. Crowe exhibited a camera, with a finder of his own construction attached. After a hearty vote of thanks to the above-named gentlemen, the meeting was adjourned to the last Thursday in February. Go Gurresgonents. *»* We cannot undertake to return rejected communications. R. L. K.—1. It is so purely a question of observation that we cannot give you any very definite directions. A good plan would be to grind a few ounces of the Indian ink with four or five times its weight of water, and to add some of this to the gelatinous solution until sufficient density is attained. 2. A small proportion of olive oil should be added to the warm mix ture, and thoroughly incorporated, as, if this is not, there is a considerable probability of adhesion taking place. 3. About one-fifth of its weight. 4. No. 5. A sufficiently well-made calendering machine cannot be obtained commercially, as far aS we know. One of the Old Sort.—It will dissolve readily in alcohol or ether. E. A. Tyler.—Thanks for your communication, which we have noted. C. W. Scriven.—No, nothing absolutely certain and reliable has been introduced up to the present time ; but it would be quite possible to construct such an apparatus. The experienced would, however, prefer to do without it, while the beginner would find that its management would far more than exhaust all his energies, leaving him nothing over for the essential features of the work. L. W. R.—1. The lens you mention will suit very well for all- round work, but it would be decidedly advantageous for you to take two others ; one of longer focus, and the other of shorter focus. 2. Double dark slides are much to be preferred. 3. Hardly so good, the longer focus lens being preferable. 4. Apply to the Assistant Secretary, Mr. Cocking, at the Gallery, 5, Pall Mall East, and he will supply you with a form of application. C. U. S.—I twill be published in course of a few weeks. Sl’ECKLEs.—The operation is somewhat risky, but the best thing is to immerse them in a weak solution of potassium cyanide, say ten grains to the ounce. Of course they must be well washed after wards. Pyro.—1. A mixture of starch paste and lamp black. 2. Yes; but a lens of shorter focus would be more suitable. 3. Possibly a weak bath of cyanide might be useful; see answer to Speckles. A. N. L.—1. If not quite as good as any, it is certainly not far behind. 2. Much more convenient in front. 3. They are sold by most stock dealers. 4. It is a question of skill, practice, and manual dexterity. 5. Probably not. Several answers and some matter are crowded out this week. *** Authors may have Reprints of their Articles at 3s. per page per hundred copies ; but the order must be given when the proof is returned.
