In glancing back over the lustrum that has elapsed since these notes were interrupted, one is impressed by the facts that (1) there has a peared no great new trend of birth of aerology, as a coherent branch o science, which made the openmg decade of the present century forever memorable in the hstory of meteorology; and that (2) the develppment of aerology has engrossed a major share of attention.’ The year 1909 was marked by the matured Humphreys-Gold explanation of what a few years ago was generally called the “isothermal layer,” but IS now almost universally known as the “stratos here.” The inappro- of a soundmg balloon sent up from Batavia in December of last year. At the bottom of the stratos here, 10.2 erature (1) of -90.9O C. (-131.6OF.1, while above t,liat fevel the temperature steadily rose to - 57.1 O C. (-70.8’ F.) at the rnkximum altitude reached by the balloon, viz, 16.2 miles. This strong gradient, is inconsistent with the idea of “isothermaJity.” A task still in progress is the determination of the rela- tions between conditions aloft and weatelier c.hanges at t,he earth’s surface. In 1912 Dr. W. N. Shaw, director of the British Meteorolo,@cal Office, introduced the idea of a “substratosphere. This he defines as “a layer of a b mosphere just under the strat,os here, at the height, of a parently often marks the height at which the velocity o 1 the wind is a masimum, and may be regarded as tslie layer of origin of t-he changes of pressure which are the dominant features of our weather maps.” While the con- cluding words of. the foregoing definition involve a de- batable hypothesis, t,lie notion of a bransition-layer be- tween troposphere and stratosphere seems conpenien t. Some charactemtics of tlie substratosphere are discussed by Dr. A. Schniauss, director of tslie Bavarian meterolog- ical service, in the current! number of Beitrage zur Physik der freien Atmos hare. tb the r e a h of s eculation. In 1911 Dr. Alfred Wegener atmosphere such as, in view of the atomic we1 lit of this en revails, would entitle it to be regarded as a distinct ’shefi” of the atmosphere. At greater heights he suggests P activity in meteorologica P research, coni arable to the priateness of the former name is il P ustrated by t,lie record miles above the earth, was found the amazing r y low tem- about 9 kilometers in the region o P the British Isles, which (Bd. 6, Heft 3.) Yet higher “sp R eres” than tlie stratosphere still belong suggested that t % e physical characteristics of a hydrogen gas, may be presumed to overlie the stratum in w % icli nitro- that the predominating constituent. of the atmosphere may be R hitherto unknown gas, lighter than hydrogen, and perhaps identical with the hypothetical “coronium” of the solar corona. This he calls “geocoronium,” and he sees in it, the o n of the most conspicuous line, hitherto unidentified, in T t e spectrum of the aurora. He computes that eocoroniuni constitutes 0.00058 per cent of the ab mosp a ere by volume at the earth’s surface, but 93 per cent at an altitude of 500 kilometers. Thus the four shells of the atmosphere according to We ener (2) are, in asceiid- ing order: Troposphere, s tratosp 5 ere, hydrogensphere, eocoroniumsphere. Dr. 0. Tetens (3), since the “auroral tne” is also found in the spectrum of the zodiacal light, prefers to call the hypothetical light gas of the u per atmos here “zodiacon.” These speculations have feen recor s ed here a t some length on account of their promi- nence in current literature, but it should be noted that the “auroral line,” althou h no lon er attributed to the heavy gas kr ton, is sti8 suscepti % le of various inter- pretations, a s is therefore an unsafe basis for hypoth- eses concerning tshe structure of the atmosphere. L. Vegard (4), who has redetermined the position of the line b observat,ions made at Boasekop, considers it an argon L e . Aerology has been annexed to the field of polar explora- tion with interesting results. Long series of up er-air were made by the recent ex editions o P Scott soundinT and Filc ner 111 the Antarctic, and by 3 ost and Stolberg, at Godhavn, on the west coast of Greenland, in 1912-13. The latter observers sent up 120 pilot balloons, for one of which they claim the hitherto unprecedented altitude of 39 kilometers (24.2 miles) above sea level.@) They were unable to find at any altitude evidence of a regular circumpolar whirl in the atmosphere. A timely summary of the immense body of international kite and balloon observations was prepared by Mr. E. Gold in 1912, and has recently been published as Geophysical Memoir No. 5 of the British Meteorological OBice. The application of aerology to the needs of the aeronaut has given birt,li to a new subbranch of science, “aero- nautical meteorology.” Its content is perhaps best rep- resented and delimited in a very practical little work bx Dr. Franz Linke, entitled “Aeronautische Meteorologie (2 vols., Frankfurt a. M., 1911). At the beginning of the year 1911 the world’s fist aeronautical weather bureau was organized in Germany. Observations of the air currents at vax~ous alhtudea axe made daily With pilot balloons at a score of stations scab tered over that empire and telegraphed to the Linden- her Observatory, whence bulletins are issued to all parta The measurement of solar radiation is still a capital problem, as it was five years ago. The most definite step in advance has been Abbot’s redetermination of the solar constant (1.922 standard calories per square centimeter per minute at mean solar distance, with fluctuations to the extent of about 10 per cent). Abbot (6) is now endertvor- ing to check these results b means of observations ob- attention has recently been devoted to attempts tomeasure separately tohe kind or kinds of radiation having most influ- ence u on plant growth and other biological processes(7). mechanics, a new personality has m e n , viz, Prof. V.
