ECLIPSE METEOROLOGY AND ALLIED PROBLEMS. 



The track of the total solar eclipse of May 28, 1900, crossed the 

 Southern States from New Orleans to Norfolk and afforded an unusual 

 opportunity for studying some of the physical problems connected 

 with the effects of solar radiation in the earth's atmosphere. The 

 observations made in the eclipse track have been discussed by Prof. 

 Frank II. Bigelow, and the results appear in Bulletin I, Weather 

 Bureau, 1902, "Eclipse meteorology and allied problems." It is 

 there shown what j)reliminary meteorological observations should be 

 made for determining the position of eclipse stations. Professor 

 Bigelow also shows that the so-called " ecliiise cyclone " does not exist 

 in the atmosphere and that the shadow bands are an absorption of 

 light effect on the sun's crescent which is confined to the lowest layers 

 of the atmosphere. A review of the scientific status of the problems 

 of solar physics follows, in which the parallelism between the meteor- 

 ology of the atmosphere of the sun and that of the earth is indicated.
