If one can grasp a conception that does have a center, even though no circumference, he has got hold of a very valuable generalization. DR. E. E. SOUTHARD, Boston: Dr. Jelliffe has just brought into ridicule what he terms "pinhole psychiatry;" but as I remember it, there is a technical method in psychology whereby things may be more clearly visible through a pin-hole!
It was evident that for countless ages radium torches had been applied to this pinhole, and for what purpose there could be but a single answer the mechanism of the lock was actuated by light rays; and I, John Carter, Prince of Helium, held the combination in my hand scratched by the hand of my enemy upon his own torch case.
And she might have inserted just below the pinhole the illuminating note that, after unfastening the string, Dalton had forgotten to return it. And then there had come an August morning the following Monday, to be exact when, his coffee untasted, he had sat staring at a paragraph in the financial column of a London paper, not daring to lay it down for fear she would pick it up.
SHAVING SOAP. Cut half a pound of fine white soap in thin slices, add half an ounce of salt of tartar, and mix them with full half a pint of spirits of wine. Put the ingredients into a quart bottle, tie it down with a bladder, digest it in a gentle heat till the soap is dissolved, and let the air escape through a pinhole in the bladder.
Photography is an undeniable esthetic problem upon our modern artistic horizon. The idea of photography as an art has been discussed no doubt ever since the invention of the pinhole. In the main, I have always said for myself that the kodak offers me the best substitute for the picture of life, that I have found.
Timing my operations carefully, I held the torch to the small aperture in the door, regulating the intensity of the light by means of the thumb-lever upon the side of the case. For fifty tals I let three units of light shine full in the pinhole, then one unit for one xat, and for twenty-five tals nine units. Those last twenty-five tals were the longest twenty-five seconds of my life.
The 'depth of focus' means the distance before and behind the point in theoretically accurate focus, at which objects are sufficiently focussed, for the purpose the photographer has in view. This length is greatest when only the central portion of the lens is in use. It is greatest with a pinhole, and least with a full aperture.
In the course of something more than an hour Jack had completed his work and showed a much larger print of Billy's pinhole photograph than was possible from the original plate, and also a print from the latter. "Now look at these two, first the little one and then the big," he said, "and tell me what is the difference."
He had uncovered another picture carefully. We could not see it, but as he looked at it McLoughlin fairly staggered. "Wh where did you get that?" he gasped. "I got it where I got it, and it is no fake," replied Kennedy enigmatically. Then he appeared to think better of it. "This," he explained, "is what is known as a pinhole photograph.
Are these abiding impressions mere signal-marks, like the letters of a book, which impart ideas to the mind? or are they actual picture-images, inconceivably smaller than those made for us by artists, in which, by the aid of a microscope, we can see, in a space not bigger than a pinhole, a whole family group at a glance?
