"Some plates were fumed with ammonia; these fogged under the pyro

solution. The proportions set down were only taken at random, and are

certainly not as sensitive as might be procured under trials. The

remaining emulsion was left shut up in a box in the dark room, and tried

on the third day after preparation; but the sensibility had, it seems,

greatly diminished, though the emulsion, when rendered fluid by gently

warming, appeared creamy, and the bromide thoroughly suspended. Some of

this was now applied to some pieces of paper by means of a glass rod,

and hung up to surface dry, then dried fully on the warmed level plate,

and treated as sensitised paper.

"One kind of paper, that evidently was largely adulterated by some earthy

base, dried without any brilliancy, but gave, under exposure of a

negative for thirty seconds, very nicely toned prints when developed

with a weak solution of pyro. Some old albumenized paper of Marion's was

tried, the emulsion being poured both on the albumen side, and, in other

pieces, on the plain side; but the salting evidently greatly interfered,

the resulting prints being dirty-looking and greyed all over.

"These papers, fumed with ammonia, turned grey under development. They

printed very slowly, even in strong sunlight, and were none of them left

long enough to develop into a full print. After washing they were

cleared by weak hypo solution. It is very possible the iron developer

may be employed for the glass prints, provided the acidification does

not render the gelatine soft under a development.

"The slowness may depend in part on the proportions of bromide and

nitrate not being correctly balanced, especially as the ordinary, not

the anhydrous, bromide was used, and on the quantities being too small

for the proportion of gelatine. Whether the plates would be more

sensitive if used when only surface dry is a question of experiment;

also, whether other bromides than the one tried may not prove more

advantageous in the presence of the neutral salt resulting from the

decomposition, or the omission or decrease of the quantity of _aqua

regia_. Very probably also the development by gallic acid and acetate of

lead developer may furnish better results than the plain pyro.

"As there will be no chance of my being able to continue these

experiments, they are placed in their crude state before the readers of

the Journal, and may eventually receive correction and improvement under

abler hands. So far as can be judged, the process seems quite worth more

carefully conducted experiments, and, if found advantageous, adds

another handle to the photographer's wheel.

R. L. Maddox, M.D."

After perusing the above, it will be evident to any one that Dr. Maddox

very nearly arrived at perfection in his early experiments. The slowness

that he complains of was caused entirely by not washing the emulsion to

discharge the excess of bromide, and the want of density was due to the

absence of a restrainer and ammonia in the developer. He only made

positive prints from negatives; but the same emulsion, had it been

washed, would have made negatives in the camera in much less time. Thus,

it will be seen, that Dr. Maddox, like the Rev. J. B. Reade, threw the

ball, and others caught it; for the gelatine process, as given by Dr.

Maddox, is only modified, not altered, by the numerous dry plate and

gelatino-bromide paper manufacturers of to-day.

Meanwhile collodion held the field, and many practical men thought it

would never be superseded.

In this year Sir John Herschel died at a ripe old age, seventy-nine.

Photographers should revere his memory, for it was he who made

photography practical by publishing his observation that hyposulphite of

soda possessed the power of dissolving chloride and other salts of

silver.

FOURTH PERIOD.

GELATINE SUCCESSFUL.

In 1873, Mr. J. Burgess, of Peckham, London, advertised his

gelatino-bromide emulsion, but as it would not keep in consequence of

decomposition setting in speedily, it was not commercial, and therefore

unsuccessful. It evidently required the addition of some preservative,

or antiseptic, to keep it in a workable condition, and Mr. J. Traill

Taylor, editor of the _British Journal of Photography_, made some

experiments in that direction by adding various essential oils; but Mr.

Gray--afterwards the well-known dry plate maker--was most successful in

preserving the gelatine emulsion from decomposition by the addition of a

little oil of peppermint, but it was not the emulsion form of

gelatino-bromide of silver that was destined to secure its universal

adoption and success.

At a meeting of the South London Photographic Society, held in the large

room of the Society of Arts, John Street, Adelphi, Mr. Burgess

endeavoured to account for his emulsion decomposing, but he did not

suggest a remedy, so the process ceased to attract further attention.

Mr. Kennett was present, and it was probably Mr. Burgess's failure with

emulsion that induced him to make his experiments with a sensitive

pellicle. Be that as it may, Mr. Kennett did succeed in making a

workable gelatino-bromide pellicle, and obtained a patent for it on the

20th of November, 1873. I procured some, and tried it at once. It gave

excellent results, but preparing the plates was a messy and sticky

operation, which I feared would be prejudicial to its usefulness and

success. This I reported to Mr. Kennett immediately, and found that

his own experience corroborated mine, for he had already received

numerous complaints of this objection, while others failed through

misapprehension of his instruction; and very comical were some of these

misinterpretations. One attempted to coat the plates with the _end_ of

the stirring-rod, while another set them to drain in a rack, and those

that did succeed in coating the plates properly, invariably spoiled

them by over-exposure or in development. He was overwhelmed with

correspondence and visitors, and to lessen his troubles I strongly

advised him to prepare the plates himself, and sell them in that form

ready for use. He took my advice, and in March, 1874, issued his first

batch of gelatino-bromide dry plates; but even that did not remove his

vexation of spirit, nor lessen his troublesome correspondence. Most of

his clients were sceptical, and exposed the plates too long, or worked

under wet-plate conditions in their dark rooms, and fog and failure were

the natural consequences. Most, if not all, of his clients at that time

were amateurs, and it was not until years after, that professional

photographers adopted the dry and abandoned the wet process. In fact, it

is doubtful if the profession ever tried Mr. Kennett's dry plates at

all, for it was not until J. W. Swan and Wratten and Wainwright issued

their dry plates, that I could induce any professional photographer to

give these new plates a trial, and I have a very vivid recollection

of the scepticism and conservatism exhibited by the most eminent

photographers on the first introduction of gelatino-bromide dry plates.

For example, when I called upon Messrs. Elliott and Fry to introduce to

their notice these rapid plates, I saw Mr. Fry, and told him how rapid

they were. He was incredulous, and smilingly informed me that I was an

enthusiast. It was a dull November morning, 1878, and I challenged him,

not to fight, but to give me an opportunity of producing as good a

picture in quarter the time they were giving in the studio, no matter

what that time was. This rather astonished him, and he invited me up to

the studio to prove my statement. I ascertained that they were giving

_ninety_ seconds--a minute and a half!--on a wet collodion plate, 10 by

8. I knew their size, and had it with me, as well as the developer. Mr.

Fry stood and told the operator, Mr. Benares, to take the time from me.

Looking at the quality of the light, I gave _twenty_ seconds, but Mr.

Benares was disposed to be incredulous also, and, after counting twenty,

went on with "one for the plate, and one more for Mr. Werge," but I told

him to stop, or I would have nothing more to do with the business. The

plate had twenty-two or three seconds' exposure, and when I developed in

their dark room, it was just those two or three seconds over-exposed.

Nevertheless, Mr. Fry brought me a print from that negative in a few

days, and acknowledged that it was one of the finest negatives he had

ever seen. They were convinced, and adopted the new dry plates

immediately. But it was not so with all, for many of the most prominent

photographers would not at first have anything to do with gelatine

plates, and remained quite satisfied with collodion; but the time came

when they were glad to change their opinion, and give up the wet for

the dry plates; but it was a long time, for Mr. Kennett introduced his

dry plates in 1874, and it was not until 1879 and 1880 that professional

photographers had adopted and taken kindly to gelatine plates generally.

With amateurs it was very different, and many of their exhibits in the

various exhibitions were from gelatine negatives obtained upon plates

prepared by themselves, or commercial makers. In the London Photographic

Society's exhibition of 1874, and following, several prints from

gelatine negatives were exhibited, and in 1879 they were pretty general.

Among the many exhibited that year was Mr. Gale's swallow-picture,

which created at the time a great deal of interest and controversy, and

Mr. Gale was invited over and over again to acknowledge whether the

appearance of the bird was the result of skill, accident, or "trickery;"

but I don't think that he ever gratified anyone's curiosity on the

subject. I can, however, state very confidently that he was innocent of

any "trickery" in introducing the bird by double printing, for the late

Mr. Dudley Radcliffe told me at the time that he (Mr. Radcliffe) not

only prepared the plate, but developed the negative, and was surprised

to see the bird there. This may have been the reason why Mr. Gale was so

reticent on the subject; but I am anticipating, and must go back to

preserve my plan of chronological progression.

In 1875 a considerable impetus was given to carbon printing, both for

small work and enlarging by the introduction of the Lambertype process.

Similar work had been done before, but, as Mr. Leon Lambert used to say,

he made it "facile"; and he certainly did so, and induced many

photographers to adopt his beautiful, but troublesome, chromotype

process. There were two Lamberts in the tent--one a very clever

manipulator, the other a clever advertiser--and between the two they

managed to sell a great many licences, and carry away a considerable sum

of money. I was intimate with them both while they remained in England,

and they were both pleasant and honourable men.

On January 18th, 1875, O. G. Rejlander died, much to the regret of all

who took an interest in the art phase of photography. Rejlander has

himself told us how, when, and where he first fell in love with

photography. In 1851 he was not impressed with the Daguerreotypes at the

great exhibition, nor with "reddish landscape photographs" that he saw

in Regent Street; but when in Rome, in 1852, he was struck with the

beauty of some photographs of statuary, which he bought and studied,

and made up his mind to study photography as soon as he returned to

England. How he did that will be best told by himself:--"In 1853, having

inquired in London for the best teacher, I was directed to Henneman. We

agreed for so much for three or five lessons; but, as I was in a hurry

to get back to the country, I took all the lessons in one afternoon!

Three hours in the calotype and waxed-paper process, and half-an-hour

sufficed for the collodion process!! He spoke, I wrote; but I was too

clever. It would have saved me a year or more of trouble and expense had

I attended carefully to the rudiments of the art for a month." His first

attempt at "double printing" was exhibited in London in 1855, and was

named in the catalogue, _group printed from three negatives_. Again, I

must allow Mr. Rejlander to describe his reasons for persevering in the

art of "double printing":--"I had taken a group of two. They were

expressive and composed well. The light was good, and the chemistry of

it successful. A very good artist was staying in the neighbourhood,

engaged on some commission. He called; saw the picture; was very much

delighted with it, and so was I. Before he left my house he looked at

the picture again, and said it was 'marvellous,' but added, 'Now, if I

had drawn that, I should have introduced another figure between them, or

some light object, to keep them together. You see, there is where you

photographers are at fault. Good morning!' I snapped my fingers after he

left--but not at him--and exclaimed aloud, 'I can do it!' Two days

afterwards I called at my artist-friend's hotel as proud as--anybody. He

looked at my picture and at me, and took snuff twice. He said, 'This is

another picture.' 'No,' said I, 'it is the same, except with the

addition you suggested.' 'Never,' he exclaimed; 'and how is it possible?

You should patent that!'" Rejlander was too much of an artist to take

anything to the Patent Office.

When I first saw his celebrated composition picture, "The Two Ways of

Life," in the Art Treasures Exhibition at Manchester in 1857, I

wondered how he could have got so many men and women to become models,

and be able to sit or stand in such varied and strained positions for

the length of time then required by the wet collodion process; but my

wonder ceased when I became acquainted with him in after years, and

ascertained that he had the command of a celebrated troupe, who gave

_tableaux vivants_ representations of statues and groups from paintings

under the direction and name of "Madame Wharton's _pose plastique_

troupe." What became of the original "Two Ways of Life" I do not know,

but the late Henry Greenwood possessed it at the time of Rejlander's

death, for I remember endeavouring to induce Mr. Greenwood to allow it

to be offered as a bait to the highest contributor to the Rejlander

fund; but Mr. Greenwood's characteristic reply was, "Take my purse, but

leave me my 'Two Ways of Life.'" Mr. Rejlander kindly gave me a reduced

copy of his "Two Ways of Life," and many other examples of his works,

both in the nude and semi-nude. Fortunately Rejlander did not confine

himself to such productions, but made hundreds of draped studies, both

comic and serious, such as "Ginx's Baby," "Did She?," "Beyond the Bible,"

and "Homeless." Where are they all now? I fear most of them have faded

away, for Rejlander was a somewhat careless operator, and he died before

the more permanent process of platinum printing was introduced. When

Rejlander died, his widow tried to make a living by printing from his

negatives, but I fear they soon got scattered. Rejlander was a genial

soul and a pleasant companion, and he had many kind friends among

members of the Solar Club, as well as other clubs with which he was

associated.

There is one more death in this year to be recorded, that of Thomas

Sutton, B.A., the founder and for many years editor of _Photographic

Notes_, and the inventor of a panoramic camera of a very clumsy

character that bore his name, and that was all. Mr. Sutton was a very

clever man with rather warped notions, and in the management of his

_Photographic Notes_ he descended to the undignified position of a

caricaturist, and published illustrations of an uncomplimentary

description, some of which were offensive in the extreme, and created a

great deal of irritation in some minds at the time.

In 1877 Carey Lea gave his ferrous-oxalate developer to the world, but

it was not welcomed by many English photographers for negative

development, though it possessed many advantages over alkaline pyro. It

was, however, generally employed by foreign photographers, and is now

largely in use by English photographers, especially for the development

of bromide paper, either for contact printing or enlargements. In the

early part of this year, Messrs. Wratten and Wainwright commenced to

make gelatino-bromide dry plates, and during the hot summer months Mr.

Wratten found it necessary to precipitate the gelatine emulsion with

alcohol. This removed the necessity of dialysing, and helped to lessen

the evils of decomposition and "frilling."

The most noticeable death in the photographic world of this year was

that of Henry Fox Talbot. He was born on February the 11th, 1800, and

died September 17th, 1877, thus attaining a ripe old age. I am not

disposed to deny his claims to the honour of doing a great deal to

forward the advancement of photography, but what strikes me very much is

the mercenary spirit in which he did it, especially when I consider the

position he occupied, and the pecuniary means at his command. In the

first place, he rushed to the Patent Office with his gallo-nitrate

developer, and then every little improvement or modification that he

afterwards made was carefully protected by patent rights. With a

churlishness of spirit and narrow-mindedness it is almost impossible to

conceive or forgive, he tried his utmost to stop the formation of the

London Photographic Society, and it was only after pressing

solicitations from Sir Charles Eastlake, President of the Royal Academy,

and first President of the London Photographic Society, that he

withdrew his objections. The late Peter le Neve Foster, Secretary of the

Society of Arts, told me this years after, and when it was proposed to

make Fox Talbot an honorary member of the Photographic Society, Mr.

Foster was opposed to the proposition. Then the action that he brought

against Sylvester Laroche was unjustifiable, for there really was no

resemblance between the collodion and calotype means of making a

negative, except in the common use of the camera, and the means of

making prints was the same as that employed by Thomas Wedgwood, while

the fixing process with hyposulphite of soda was first resorted to by

the Rev. J. B. Reade, on the published information of Sir John Herschel.

On March 29th, 1878, Mr. Charles Bennett published his method of

increasing the sensitiveness of gelatino-bromide plates. It may be

briefly described as a prolonged cooking of the gelatine emulsion at a

temperature of 90 deg., and, according to Mr. Bennett's experience, the

longer it was cooked the more sensitive it became, with a corresponding

reduction of density when the prepared plates were exposed and

developed.

April 20th of this year Mr. J. A. Spencer died, after a lingering

illness, of cancer in the throat. Mr. Spencer was, at one period in the

history of photography, the largest manufacturer of albumenized paper in

this country, and carried on his business at Shepherd's Bush. In 1866 he

told me that he broke about 2,000 eggs daily, merely to obtain the

whites or albumen. The yolks being of no use to him, he sold them, when

he could, to glove makers, leather dressers, and confectioners, but they

could not consume all he offered for sale, and he buried the rest in his

garden until his neighbours complained of the nuisance, so that it

became ultimately a very difficult thing for him to dispose of his waste

yolks in any manner. After the introduction of Swan's improved carbon

process, he turned his attention to the manufacture of carbon tissue,

and in a short time he became one of the partners in the Autotype

Company, and the name of the firm at that period was Spencer, Sawyer,

and Bird; but he ceased to be a partner some time before his death.

At the South London Technical Meeting, held in the great hall of the

Society of Arts, I exhibited my non-actinic developing tray, and

developed a gelatine dry plate in the full blaze of gas-light. A short

extract from a leader in the _Photographic News_ of November 14th, 1879,

will be sufficient to satisfy all who are interested in the matter.

"Amongst the many ingenious appliances exhibited at the recent South

London meeting, none excited greater interest than the developing tray

of Mr. Werge, in which he developed in the full gas-light of the room a

gelatine plate which had been exposed in the morning, and exhibited to

the meeting the result in a clean transparency, without fog, or any

trace of the abnormal action of light.... We can here simply record the

fact, interesting to many, that the demonstration before the South

London meeting was a perfect success."

1880 had a rather melancholy beginning, for on January the 15th, Mr.

George Wharton Simpson died suddenly, which was a great shock to every

one that knew him. I had seen him only a few days before in his usual

good health, and he looked far more like outliving me than I him;

besides, he was a year my junior. The extract above quoted was the last

time he honoured me by mentioning my name in his writings, though he had

done so many times before, both pleasantly and in defending me against

some ill-natured and unwarrantable attacks in the journal which he so

ably conducted for twenty years.

Mungo Ponton died August 3rd, 1880. Though his discovery did little or

nothing towards the development of photography proper, it is impossible

to allow him to pass out of this world without honourable mention, for

his discovery led to the creation and development of numerous and

important photo-mechanical industries, which give employment to numbers

of men and women. When Mungo Ponton announced his discovery in the

_Edinburgh New Philosophical Journal_ in 1839, he probably never dreamt

that it would be of any commercial value, or he might have secured

rights and royalties on all the patent processes that grew out of it;

for Poitevin's patent, 1855, Beauregard's, 1857, Pouncy's, 1858 and

1863, J. W. Swan's, 1864, Woodbury's, 1866, all the Autotype and

Lambertype and kindred patents, as well as all the forms of Collotype

printing, are based on Ponton's discovery. But so it is: the originator

of anything seldom seeks any advantage beyond the honour attached to the

making of a great invention or discovery. It is generally the petty

improvers that rush to the Patent Office to secure rights and

emoluments, regardless of the claims of the founders of their patented

processes.

On March 2nd, 1880, I delivered a lecture on "The Origin, Progress, and

Practice of Photography" before the Lewisham and Blackheath Scientific

Association, in which I reviewed the development of photography from its

earliest inception up to date, exhibited examples, and gave

demonstrations before a very attentive and apparently gratified

audience.

On the 27th May, 1880, Professor Alfred Swaine Taylor died at his

residence, 15, St. James's Terrace, Regent's Park, in his seventy-fourth

year. He was born on the 11th December, 1806, at Northfleet in Kent, and

in 1823 he entered as a student the united hospitals of Guy's and St.

Thomas's, and became the pupil of Sir Astley Cooper and Mr. Joseph Henry

Green. His success as a student and eminence as a professor, lecturer,

and author are too well-known to require any comment from me on those

subjects, but it is not so generally known how much photography was

indebted to him at the earliest period of its birth. In 1838 Dr. Taylor

published his celebrated work, "The Elements of Medical Jurisprudence,"

and in 1840 he published a pamphlet "On the Art of Photogenic Drawing,"

in which he advocated the superiority of ammonia nitrate of silver over

chloride of silver as a sensitiser, and hyposulphite of lime over

hyposulphite of soda as a fixer, and the latter he advocated up to the

year of his death, as the following letter will show:--

"_St. James's Terrace, February 10th, 1880._

"Mr. Werge.

"Dear Sir,--I have great pleasure in sending you for the purpose of your

lecture some of my now ancient photographs. They show the early

struggles which we had to make. The mounted drawings were all made with

the _ammonia nitrate_ of silver; I send samples of the paper used. In

general the paper selected contained chloride enough to form ammonia

chloride. I send samples of unused paper, procured in 1839--some salted

afterwards.
