of aluminium or wood or five-eighths of an inch of lead; and the third greatly re- sembles X-rays. It is estimated that the total exhaustion of a gramme of radium would yield from 10000 to 100000 times the energy of hyrogen and oxygen when combining to form water. Some internal energy of the atoms must be called out. and the atomic disintegration seems to yield helium.
 In the vast space between Mars and yu- piter. little planet was discovered on
 the first day of the nineteenth century,
 and since then the former gap in the
 plan of the solar system has been filled by
 the finding of ring of nearly 800 tiny
 worlds. It Is calculated that these aste- rods together would form a globe SsD miles in diameter. or a little more than a thousa ldth of the size of the earth. Vesta, the largest of the group, Is 51S
 miles in diameter. and Eros, with a diam eter of scarcely twenty miles, has been | watched of late with exceptional interest
 because at times 1t approaches the earth
 closer than any other heavenly body ex- | cept the moon.
 The oldest wood carving known Is a | sycamore statuette, representing an over seer of pyramid builders, which dates 1 from 39OO B. C.. and is in Cairo museum. l The idea that rheumatism is conta gious l is gaining ground .n Germany, and at | Leipsic patients are actually isolated to | prevent the spread of the disease. The 1 evidence in the support of this view IS | claimed to be accommodating. Children be- | come sufferers from articular rhCumat- | ism a few days after their parents are attacked, and NJ. TalamSn has recorded | the case of child who had arricular rheumatism for eight days, and whose | younger sister, sleeping in the same room. was attacked a few days later with a rheumatic affection that proved fatal. | Rheumatism often seems to pass from l one to the other of two married people. | many cases of this kind-as when a per- | fectly healthy man is taken a few days | after one of his wifes rheumatic att
 tacks-strengthening the theory of conta- 1 zion.
 | Remarkable results in star photography | with comparatively inexpensive apparatus l have been reported by Professor Schae- | berle. His telescope was a parabolic re- | Hector of short focus. the mirror being l thirteen inches in diameter. with focus of twenty inches and exposures of five | minutes gave star images that were be- yond the reach of the thirty-six inch Lick
 telescope and that required exposures of l two hours with the thirty-slX inch Cross | iy reflector. Stars fainter than the sev- | enteenth magnitude were included. Traction tests with electric automobiles | in London have shown a surprising in- | crease of the starting pull on oiled pave-
 ments. pull of 30 pounds per ton was
 needed to start on dry asphalt, 70 1-2 | pounds on wood pavement, and 104 pounds | on dry macadam. On greasy asphalt a | pull of nearly 79 pounds per ton was nec- l essary.
