Look through a pin-hole in a card at a uniform white surface as the white shade of an ordinary reading-lamp. With the right eye look through the pin-hole, the left eye being closed. One can thus see and observe the rate of movements of his own iris. Experiment 179. To show the blind spot.

Sparling kept away, but a pair of eyes representing him was peering through a pin-hole in the canvas stretched across the main opening where the ticket takers stood when at work. "That's great, kid! Great, you bet!" shouted Mr. Kennedy after a successful trial of their new apparatus. With light heart, an expansive grin overspreading his countenance, the lad ran to the cook tent for his supper.

Around the pin-hole are raised and depressed concentric circles intended for ornament; and the "dishing" towards the rim is regular as if turned by machinery. We have seen as yet nothing like this work; nor shall we see anything superior to it. All are nether millstones, so carefully smashed that one can hardly help suspecting the kind of superstitious feeling which suggested iconoclasm.

Seventy-four years old, she looked every minute of her time. Her thin legs were encased in straight-lined pants of linen stiff- textured and shiny-black. Her scraggly grey hair was drawn unrelentingly and flatly back from a narrow, unrelenting forehead. Eyebrows she had none, having long since shed them. Her eyes, of pin-hole tininess, were blackest black. She was shockingly cadaverous.

The strong wind changed not again for fourteen days, and its effect was a permanent one; so that people might have fancied that an enemy had indeed cut the dykes somewhere a pin-hole enough to wreck the ship of Holland, or at least this portion of it, which underwent an inundation of the sea the like of which had not occurred in that province for half a century.

There was small danger of their foolish prayers and superstitious ceremonies evoking a deity from the well-ordered, self-evolved sphericity of interacting law, where not a pin-hole of failure afforded space out of which he might creep.

At the same time this will help us to learn more about the properties of levity-space. The optical phenomenon which we shall discuss in this sense is that of the so-called pin-hole camera.

Falchion interrupted, her hand with the ivory knife now moveless in that belt of sunlight across her knees. "His criminal mistake," Ruth repeated, wincing "might not it become changed into mercy, and the man be safe?" "Safe? Perhaps. But he would tire of the pin-hole just the same. . . . My dear, you do not know life." "But, Mrs.

Not an inch of the massive oaken struts above did they fail to scrutinize, and they made experiments with smoke and water, to learn if, at any point, so much as a pin-hole existed in the face of the stucco. But it was solid, and spread evenly to a considerable depth.

Cork it again and the gas bubbles cease to rise and finally disappear. If you make a pin-hole in the cork the gas will escape slowly, without a bubble. You must decompress the human body slowly, by stages, to let the super-saturated blood give up its nitrogen to the lungs, which can eliminate it. Otherwise these bubbles catch in the veins, and the result is severe pains, paralysis, and even death.
