Cats and dogs do not get much "kick" out of movies. During recent tests made by Dr. Victor Mendel of Berlin, animals and birds showed a rather surprising lack of response to moving pictures. The pictures were especially selected for each animal and animal group, and the experiments were made in an exhibition room especially adapted to the purpose.
The response of dogs was practically nil. Neither St. Bernard, setter, spaniel, poodle nor collie gave the slightest attention to the pictures. Only a little mongrel of doubtful origin evinced a momentary interest by sniffing at the human figures on the screen. The experiments with cats were much more favorable. Of five subjects three responded actively, showing fight upon the appearance of a big dog on the screen.
"Cannon-balls" of stone, dating back to a time before there were any cannon to propel them, have been excavated from the ruins of an ancient arsenal in the citadel of the old Greek city of Pergamon in Asia Minor. The exploration was conducted by a party of German scientists under the leadership of Dr. Theodor Wiegand, who has just reported his findings in Berlin.
Though these balls were never fired from cannon, they were artillery ammunition nevertheless. In the third century B.C., when they were carved, artillery consisted of huge crossbows or long wooden arms swung on counterweights, which could send stones and heavy darts whizzing through the air for considerable distances.
