WE OLD AGE' IS INHERITED, SCIENCE FINDS Preliminary Results of Studies Are Reported by Biologists. By Science Service BALTIMORE, May 22 —Oliver Wendell Holmes’ advice to “advertise for a couple of parents both belonging to long-lived families” in order to live to a ripe old age has been tested actuarially by Dr. Raymond Pearl and his associates in the department of biology of the school of hygiene and public health of Johns Hopkins university here. He finds that longevity is inherited and that there are scieniflc grounds for the widely prevalent idea that length of days tends s o run in families. Preliminary reults of his extensive studies of the nheritance of longevity are reiorted in the current issue of Hunan Biology. Use Insurance Methods Thousands of family history recrds collected by Dr. Pearl’s department were used in the investigation. Using methods by which life insurance companies determine the life tables upon which they base their rates. Dr. Pearl reports, “that the expectation of life of sons of fathers dying or living at 80 or over years of age, is greater at all ages from birth on, than the expectation of life of sons of fathers dying at ages between 50 and 79 years inclusive, and is still greater than the expectation of life of sons of fathers dying under 50 years of age.” In order to establish still more soundly the conclusions, Dr. Pearl also studied the expectation of life of parents of long-lived sons and daughters in comparison with the expectation of life of parents of short-lived sons and daughters. Many other similar actuarial comparisons were made. 10,000 Records Studied Parents of children dying at 50 years or over live longer by 7 to 28 per cent, than parents of children who die under 50 years of age. Grandparents whose children live to more than 50 years of age themselves by the life tables have lifetimes 7 to 59 per cent longer than the grandparents with shorter lived children. More than half a million years of life were contained in the records upon which the studies were based. Extensive pedigrees of more than 100,000 members of white Baltimore families were available for* the study, each record of which was obtained by a trained field worker.

They’re just as aristocratic as they look, these Warrenton Drag hounds, which are part of the pack brought to this country to lead smart society fields at the Virginia Beach (Va.) drag hunts. If you’ll believe the masters of some of the eastern hunt clubs attending the drag, these are the finest and best trained fox hounds in this country, and are valued from SSOO to SI,OOO each.

COUNTY STUDIES PIPEDGAS PLAN Right-of-Way Sought for Line to Muncie. Petition for a natural gas pipe line franchise across Marion county, en route from Muncie to the state, line, was being considered by county commissioners today following its filing Wednesday by the Ohio Fuel Gas Company of Columbus, O. Work on the line, designed to connect the Ohio-West Virginia natural gas field with the pipe line running northeast from the Texas fields, is expected to start within thirty days. Joseph J. Daniels, attorney, explained there was no connection between the line and the introduction of natural gas into Indianapolis, now under advisement by city and county officials. Friendly relationship exists between the company and the Marion County Gas Corporation, which proposes to lease the Indianapolis gas plant, it is said. Because of this

relationship, it is probable the Ohio corporation expects to furnish the local company with natural gas. CACTUS STATE FLOWER Arizona Piles Additional Honors on Once-Hq,ted Plants.

AURORA LESS THAN 100 MILES FROMJSROUND Northern Lights Proved Far Closer to Earth Than Had Been Believed. / Bv Science Service TORONTO, May 22.—The aurora borealis, least understood of heavenly phenomena, is not as distant from the earth as has been thought. Fifty to seventy-five miles from the ground is the height fixed for the eerie flashes of light in a report made to the Royal Society of Canada Thursday by Professor J. C. McLennan, Dr." Hugh Wynne-Rob-erts and Dr. H. J. C. Ireton of the physics department of the University of Toronto. Utilizing the fact that the northern lights are visible farther south in eastern Canada than anywhere else in the northern hemisphere, the physicists photographed displays last January and February. They set up two observing stations near James bay. One was located at Blacksmith Rapids, fifty miles from Moose Factory, and the other at Coral Rapids, thirty miles ; farther south. The stations were connected by telephone lines and each was provided with .cameras similar to those used in aerial surveying. When the aurora was visible from both stations, the photographers focused their cameras on areas of the sky selected by telephone, and took simultaneous pictures. The exact times were compared by telephone and checked against a master clock. Reference points in the heavens were provided by the stars, photographed on the plates at the same time. When the plates were developed and compared, the triangulation method used in surveying was employed, the physicists computing a vertical triangle with one side as the line joining the two observing stations. The results show that the auroral flashes occasionally may lie 155 miles over the earth. Less than 100 miles is the usual height, however.
