The great furrows which the cat's claws had ploughed up in his face he had filled with collodion, and a rag hid the wound in his throat. I told him I should kill the cat when I came across her, but he only shook his head and turned to the open ledger before him. He read name after name of the people who had come to him in regard to their reputation, and the sums he had amassed were startling.
I had an earnest desire to acquire the art and mystery of practical photography. I bought the necessary apparatus, together with the chemicals; and before long I became an expert in the use of the positive and negative collodion process, including the printing from negatives, in all the details of that wonderful and delightful art.
Bond, then Professor Bond, director of the Harvard Observatory, again took up the matter with collodion wet plates, and in three masterly papers showed the advantages of photography in many ways. The lack of sensitiveness of the wet plate was perhaps the only reason why its use progressed but slowly.
Jerrold repeats more than once Doré's phrase, "I have lots of collodion in my head," and recounts how he could scarcely be induced to make sketches from nature, but relied upon his memory. He also speaks of Doré's system of dividing and subdividing a subject, and noting the details in their places, so that he could reproduce the whole afterward.
Collodion, which is a solution of gun-cotton in alcohol and ether, mingled with a solution of iodide and bromide of potassium, is used to form a thin coating over the glass. Before the plate is dry, it is dipped into a solution of nitrate of silver, where it remains from one to three or four minutes.
All moist or greasy applications, such as Carron oil, carbolic oil and ointments, and all substances like collodion and dry powders, which retain discharges, entirely fail to meet the indications for the rational treatment of burns, and should be abandoned. Skin-grafting is of great value in hastening healing after extensive burns, and in preventing cicatricial contraction.
Substitute for the paper a sensitive glass plate, and we obtain also a positive picture, but, unlike the paper print, the collodion or other plate will require to be developed to bring the image into view. Now this is what is termed making a transparency by contact.
After soaking in hot water, the overgrown horny layer is pared away, and the part painted daily with a saturated solution of salicylic acid in flexile collodion. [Illustration: FIG.
The collodion capsule permitted the fluids of the body to enter and provide food for the bacilli, but prevented the admission of the leucocytes to attack and destroy them. After several weeks the capsule was removed, the bacilli found still alive, and transferred to another capsule in another fowl.
Can't you smell the cold cream?" This was beyond ken, but he became more explicit. "Cold cream to the eyes and ears," said he. "To the untutored face, the sun of this heathen district is something sinful; and like enough she never heard of collodion for cracked lips in an alkali country.
