KNOWLEDGE. 



July, 1913. 



popularity of the fashion is very comprehensible ; 

 for there are always plenty of people who wish to 

 seem clever but are not. And the trick of it is 

 easily acquired. Be cynical and flippant about 

 everything, and you will get the credit of having 

 seen through the illusions of the world, and of being 

 a deeply wise man who conceals his wisdom. But 

 it is a pose and an affectation. There is really no 

 disgrace about being serious, at least occasionally, 

 nor in being honest, even almost habitually ! If I 

 seem too solemn or too enthusiastic in my vision of 

 the future when the unity of mankind shall be more 

 fully realised, I appeal from the decadent trifler of to- 



day to the vigorous thinker of to-morrow — from Philip 

 drunk with sophistication and selfishness to Philip 

 sober with clear eyes and better ideals. Better times 

 are coming. We are beginning to see that we are not a 

 " concourse of warring atoms," but a vast multitude 

 of units which fit together and make up an organism ; 

 and that what is good or bad for the organism is 

 good or bad for the units. Solidarity and homo- 

 geneousness are the watchwords. Individualism 

 has been over-accentuated. We must see 

 humanity steadily, and see it whole — a whole, 

 however, within a still larger Whole of the entire 

 Cosmos. 



SOLAR DISTURBANCES DURING MAY, 1913 



By FRANK C. DENNETT. 



May has been remarkable for the small amount of disturbance 

 upon the Sun. The disc has been examined every day, but on 

 twelve occasions (1, 3, 6, 8, 12, 13, 19, 20, 22, 23, 29, and 31) 

 it has appeared to be quite free from disturbance, bright or 

 dark. Short-lived pores were noted on three (11, 16, and 25), 

 and faculae on the remaining sixteen. The longitude of the 

 central meridian at noon on May 1st was 224° 27'. 



On May 1st and 2nd the granulation of the photosphere 

 was noted as being very fine all over the disc. On the 11th 

 there appeared to be very many minute pores in the central 

 portion of the disc and in northern latitudes. One showed as 

 a small irregular umbra near the central meridian (94°) with 

 large faculic flecks about it. 



On the 16th, in the afternoon, pores showed in high 

 latitudes both north and south, well to the west of the central 

 meridian, which was 24°. 



On the 25th, at 5.15 p.m., in high latitude south-east, about 

 six days on the disc a small pore showed in a rough-looking 

 area, nearing the central meridian, which was 264° 13'. 



Unfortunately no measures were made in either of these cases. 



The faculic display was also of a most meagre description. 

 On the 4th and 5th a faculic cloud was measured at longitude 

 244°, south latitude 40 c . On the 14th and 15th a small 

 bright facula was situated at 339°, 68° South ; on the 16th 

 and 17th a small facula at 312°, 10° North, and on the 17th, a 

 paler one at 310°, 12° South; on the 24th a pale one at 

 218°, 33° South, and another at 208°, 21° North. Perhaps 

 the most interesting one was a brilliant granule, less than 

 7° from the South Pole, seen on the 26th, 27th, 30th, and 

 June 4th. 



Other faculae were seen, but not measured, near the 

 western limb on the 21st and 28th; south-western on the 

 7th, 10th, 17th, 18th, and 30th; south-eastern on the 10th, 

 14th, 15th, 17th, and 25th; and north-eastern on the 2nd, 

 9th, and 10th. 



The Chart was constructed from the observations of 

 Messrs. John McHarg, A. A. Buss, C. Frooms, E. E. Peacock, 

 and the writer.

THE MOON. 



The plate of the Moon given in Figure 267, on page 261, shows much fine detail, particularly in the Maria Imbrium, Nubium and 

 Crisium ; Tycho, Copernicus, Kepler and Aristarchus are very well defined. From the sketch-maps published in " Knowledge " 

 during 1909 all the points to be seen in this plate may be identified. The image is shown as it would appear in an inverting 

 telescope. The photograph was taken at Paris on November 13th, 1902, at 2.57 a.m., with the Equatorial Coude. The 

 aperture was 23-62-ins., the focal length 59' 6" -6, and the exposure 0-6 of a second.
