I’m not sure how this prevents dog theft. If I steal your dog couldn’t I just make a noseprint of him and claim I had it all the time?

DOGS NOW NOSEPRINTED TO PROVE OWNERSHIP
Taking noseprints of dogs to guard them against loss or theft is the method being adopted by western owners. When two persons claim the same dog in court, ink noseprints, like the specimen illustrated, settle the matter. Like human fingerprints, the patterns on the nose of the dog are said not to change with age, and therefore a pet need submit but once to having its nostrils smeared with ink. No two dogs have identical patterns so a mistake is impossible.

ROOF-TOP HEAT TRAP STORES POWER FROM THE SUN

HEATING homes in January with the warmth of last summer’s sunshine —that is the exciting goal of research now under way at Cambridge, Mass. Not far from the Charles River, scientists of the Massachusetts Institute of Technology recently completed a white frame building, its sloping roof edged with a glistening battery of solar-heat traps.

Gamblers Who Always Win

The odds are that you can get odds on almost anything today because modern statisticians have really taken the risk out of chance

ONE afternoon a Lincoln, Nebraska, businessman sat in his car in a suburban gas station while his tank was being filled. As he waited, the telephone inside the station rang and presently the attendant came out.

“Are you Mr. L. R. Johansen?” he asked.

FRAME TEACHES SWIMMING
Novices at swimming may acquire confidence with the aid of an odd mechanical device, just introduced in Germany. The swimmer lies on a floating frame supported at an adjustable height in the water by pontoons, and propels it forward by placing his feet in a pair of stirrups and kicking. Thus he learns the proper motions of the legs. Oar-like paddles may also be operated with the arms. The hinged propelling fins open automatically when pushed backward against the water.

Freedom to LISTEN – Freedom to LOOK

As the world grows smaller, the question of international communications and world understanding grows larger. The most important phase of this problem is Freedom to Listen and Freedom to Look—for all peoples of the world.

Radio, by its very nature, is a medium of mass communication; it is a carrier of intelligence. It delivers ideas with an impact that is powerful … Its essence is freedom —liberty of thought and of speech.

Mother Could Fix This Radio (Jan, 1948)

This is an interesting harbinger of the huge wave changes that occurred in the electronics industry in the 50 years after this article was published. What they’ve done here is essentially modularized an entire radio into plug and play components. Their reason for doing this was to make repair simpler, but now everything is designed that way so you can use standardized components and simplify assembly. If hundreds of different devices uses the same oscillator (or Ethernet controller for that matter) you can make them a lot cheaper.

Mother Could Fix This Radio

PSM photos by Robert F. Smith

YOU don’t need to know a coil from a condenser to fix this radio. Throw-away units, as easy to change as radio tubes, contain practically everything that might go wrong in the set. Six “canned” circuits with pronged bases, designed to retail in department stores at $1.85 apiece, replace the maze of wiring located in back of the dial of a conventional radio.

Nope, nothing scary here. Who would have a problem hanging out in a tin can being dangled a few thousand feet below a blimp? I’m not really sure what the propeller is supposed to do. Are they saying there is actually an engine in the capsule?

NEW OBSERVATION CAR FOR AIRSHIP
Nicknamed the “flying fish,” a new type of observation car for airships has been constructed by a Viennese engineer. Like the “sky car,” used occasionally by United States airships, it may be lowered on a cable through the clouds while the airship is in flight. The Viennese invention, however, has its own propeller, enabling the observer to maneuver his gondola. The fishlike tail is flexible and may be swung from side to side, serving as a rudder. Because of its slender, streamlined shape, the gondola is invisible from the earth at comparatively low altitudes.

YOUR LOOKS AND PERSONALITY

by Amram Scheinfeld
Condensed from a chapter of the book, The Human Heredity Handbook

Personality refers to all of a human individual’s behavior traits, plus all the other special qualities of mind, body, sex, and social adjustment that distinguish him as a particular person.

Second, personality refers to qualities developed by one person in relation to other persons. Strictly speaking, then, only human beings can be considered as having “personalities.” Although we might like to think that cats, dogs and other animals also have “personalities,” scientists prefer to speak of their traits as “behavior patterns.”

Wow, not only are high-heels good for women, apparently they give them bigger breasts!

THE HIGH-HEELS CONTROVERSY

High-heeled shoes are physically and psychologically best for women’s wear, says a British doctor, contrary to the opinions of many authorities.

Careful tests on special scales have shown, said Dr. Owen McDonagh, that high heels throw the weight onto the heel rather than onto the toes, as is frequently charged.

Your Shoulder Blades Tell How Old You’ll Be

DR. WILLIAM WASHINGTON GRAVES, medical scientist of the University of St. Louis, has made the unique discovery that the scapulae or shoulder-blades tell whether man is potentially healthy, longer lived and more disease resistant than his fellow-man. Dr. Graves has come to the conclusion that persons having the convex-type of shoulder blades have a better chance in life than those who have straight or concave scapulae.

ARCHITECT DESIGNS COTTON HOUSES

Houses of cotton are proposed by Lawrence Kocher, noted architect, to solve the low-cost housing problem. Models of two types; a $1,500 five-room home and a week-end house, have been designed. A weatherproof exterior is provided by a roof and walls of fireproofed cotton ducking stretched over a wooden structural frame. Inner walls are also of cotton. Insulating material may be added to exclude heat and cold. Since the canvas is flexible, it is adaptable to any shaped surface.
