1m® JULY 18,1862.] THE PHOTOGRAPHIC NEWS. 347 ist, iu 1 pint 400 grains 8 drs. 8 ozs. the last number of the News induces mo to bring the subject forward again from circumstances of casual observation only. My premises going under repair, and all useless lumber being turned out, amongst which were some old photographs printed in 1838-39-40, very few of which were faded; in referring to my Journal I find the method to vary little from that of the present time, the formula I give as follows:—Best drawing paper soaked in salting bath a few minutes composed of light i is acct- I a little I i almost I also, H er maj merits 1862. sts he re is a e difi- iced of , and ts form avalu- ons m ise sef ientitit as, has icd sur: s would surfaces as been vhich is aodifies- ng only li which te-glass one and piece of formed per, and । fluid is hrough operator ieasures Water Chloride of sodium Pin up to dry.

These photo graphs were all mounted on plate with gum water, which 1 used in mounting botanical specimens, animal preparations, &c., it contained— Turkey gum 4 ozs. Water 2 „ Saturated solution of bichloride of mercury 2 „ I am inclined to think the bichloride of mercury assists the preservation of the prints, for of late years I have used other substances for mounting, and washed the prints with great caro, and many have faded quite away.—Yours obediently, H. B. Nichols. [As the prints were on thick drawing paper, it may bo that the bichloride of mercury never camo into contact with tlio image ; if it had done so it must inevitably have acted upon it, and probably in an injurious manner, as its usual effect upon a silver print is to bleach it. The perfect condition of the prints referred to, and indeed of very many old prints, which did not receive a tithe of the washing, &c., which prints now generally receive, is somewhat puzzling. The only suggestion we can make on the subject is, that at one time prints were washed individually, and that now they arc washed in batches; a cir cumstance which materially alters the case. Wo shall have pleasure in receiving our correspondent’s account of various waterproof compounds, as the hints of practical mon on such subjects are always of value.—Ed.] r the ising spect . the uires oved pith much perseverance, and well convinced that a glorious future awaits them in this path, a well-earned reputation to be acquired, and a name to be made. If photography, as seems manifest, is to render powerful aid to military operations, and if the Government is seri- Wily disposed to attach photographers to land and sea rapeditions, it is necessary that it should clearly comprehend the importance of such a decision. Military photography, among other applications, may embrace perspective views of fortresses, military posts, ftdoubts, and general views, to accompany despatches, and furnish an explanation of the results obtained, and the means employed to obtain them. In other respects, this new ar will give greater precision than any written documents. 'Ie obtain, instantaneously, proportional and, measured per- Iptdius of the extent and distances of forts, promontories, redistribution of groups in fleets and armies : we can obtain military positions, and an infinity of essential representa- tions, without reckoning the application of the camera to topographical plans—a problem already partly resolved— and would haye been completely so if men possessing com- Pelence and leisure had devoted themselves to the art under • military point of view, instead of making of it only an object of idle curiosity. The first proposals to the Minister 4 War to establish a class of photography among the mili- ry staff were rejected. But when Marshal Vaillant suc- Med to that post, he gave it a more cordial reception. The ms of the proposal were mainly as follows :— ■ To introduce photography usefully into the army, it is M necessary to select officers devoted, apt, and especially ith a decided talent for this kind of operations. . To establish in each military school a proper course of Istruction in photography. Four or five lessons obligatory Ipon all, in order that every pupil may obtain a knowledge ofthe rudiments of the art; then, every year to make choice 05 a certain number of pupils, who, having already manipu- ated and shown a decided vocation for the art, and perfect Shem in a special establishment—the military depot, for "■stance—and by these means obtain a result doubly advan- ^Jeous; first, to endow all the young officers with a new irt; and next, to excite in them a love for the physical and Shemical sciences, which they are now very far from possess- g. To provide each regiment with the apparatus requisite for “king views, plans, &c. , It will be quite easy to stimulate and sustain the zeal of ‘hofficers by a daily application of the art to works of Eknowledged utility, such as views, maps, uniforms, horses, W material of war, and in fact of everything interesting e soldier. • will be seen from the foregoing that all that is neces- B! in order to render photography as useful to the art of as many arts and sciences already are, is, first, to recog- 4 the great aid it is capable of rendering, and then to “cniatically organize a course of instruction among the ang officers, and maintain their interest in the art by "“lly application to it. tliscellaneous. Physiognomy and PHOTOGRAPHY.—Looking over the por traits of mon who have risen abovo their fellows, who have blessed, cursed, or influenced their race, we find no common place faces—none whose visages are beneath their greatness. Napoleon thought a large nose a mark of strength of character. So it is ; but not alone the nose, but all the features are well developed in men of mark and vigour. A small and insignifi cant face is unknown to greatness. In saying so, we only claim, with the phrenologist, a largo brain, which manifests itself in a corresponding countenance. None will deny that character is expressed in the face and body; the only doubt is as to the possibility of the skill that can read its complex and intertwined signs with any certainty. Lavater did not cultivate physiog nomy in the specific spirit which alone can discover and securo truths for mankind. If any one would give to physiognomy the labour and genius Gall gave to the brain, and Professor Owen has given to comparative anatomy, there is little question but valuable results would be attained. He would have the world with him for sympathotic and admiring students, for wo are all curious about one another, and ready to take stock of each others’ attainments and possibilities. One of Lavater’s constant difficulties was in careless and incorrect portraits. Now we have photography, we can not only study the living at our leisure as they are, but can obtain faithful transcripts of the best pictures of men famous and infamous who have passed from earth.—Chambers's Journal. * I have now in use some of the wooden dishes used by me at that period ; they are made of pine wood, lined with caoutchouc and Stockholm pitch, equal parts, melted together.
