sharp ting of its bell, and tlie warning voice 

 •of the timekeeper called, ' One hundred,' 

 'Ninety,' 'Eighty,' according to the number 

 of seconds still left us. 



Just behind me Captain Molesworth and Mrs. 

 Maunder, at an equatorial with two cameras, 

 were changing plates with the confidence and 

 precision begotten of much practice. With 

 «ach camera six plates were to be exposed, and 

 all went without a hitch, but, just as the word 

 came for the sixth exposure, with a sudden 

 rush an immense flood of sunlight poured forth. 

 The eclipse had been four seconds short of the 

 time we had expected. Meantime Mr. Thwaites 

 had secured three photographs and Lieutenant 

 Morris exposed several plates in small cameras. 

 Further east Mr. Evershed, with a threefold 

 arrangement of spectroscopes, exposed plates 

 to catch the spectrum of the corona, and espe- 

 cially of the flash. Between our other occupa- 

 tions we looked up at the magnificent spectacle 

 before us. The darkness did not equal the 

 eclipses of 1886 or 1896, but the corona stood 

 out in the sky as a vast silver star, brighter and 

 more extended than when I saw it eleven 

 years before. Two fine leaf-shaped extensions 

 stretched out almost horizontally east and west, 

 whilst nearly, but not quite, on the sun's 

 equator, directed southwest, was the greatest ray 

 of all, two millions of miles in length almost, 

 pointing to where one celestial brilliant glittered 

 several degrees away. 



I had hoped to ascertain the distribution of 

 the element coronium iu the corona, but the 

 green line, which for us composes its spectrum, 

 was very faint, and was not seen at all on the 

 eastern side of the sun. On the west it was 

 traced to about 5' in height. Whilst telegraph- 

 ing we learn that Professor Naegamvalla secured 

 forty photographs at Jewar, completing his 

 program.

AMERICAN MATHEMATICAL SOCIETY. 



A REGULAE meeting of the American Mathe- 

 matical Society will be held on Saturday, Feb- 

 ruary 26th, in Eoom 301 of the Physics Build- 

 ing of Columbia University, New York City. 

 The two sessions will begin at 10:30 a. m. and 

 2:80 p. m., and the Council will meet at 2 p. 



m. From all indications this meeting promises 

 to rival in interest the recent very successful 

 annual meeting of the Society. The following 

 papers have thus far been entered for presen- 

 tation : 



1. Professor Maxime Bocher : ' The theorems 

 of oscillation of Sturm and Klein.' 



2. Dr. J. "W. Davis : ' Behavior at laboratory 

 temperatures of gas and vapor generating globes in 

 celestial spaces. ' 



3. Mr. p. R. Heyl : ' The measure of the bluutness 

 of the regular figures in four dimensional space. ' 



4. Dr. J. I. HoTCHiNSON : ' Note on the tetra- 

 hedroid. ' 



5. Dr. E. O. Lovett : ' On the symmetry of al- 

 gebraic surfaces.' 



6. Dr. G. a. Miller: 'A generalization of 

 Sy low's theorem.' 



7. Professor W. P. Osgood : ' A new proof of 

 the existence of a solution of the differential equa- 

 tion dy/dx =f( X, y), the Cauchy-Lipsohitz condition 

 not being imposed. ' 



8. Professor James Pieepont : ' The Early His- 

 tory of the Galoisian theory of equations. ' 



9. Me. Paul Saurkl : ' Note on integrating fac- 

 tors.' 



10. M. James Maclay : ' Certain double minimal 

 surfaces. ' 



11. Professor H. S. White : 'Inflexional Lines, 

 Triplets and Triangles Associated with the Plane 

 Cubic Curve.' 



The January number of the Bulletin (Vol. 

 VII., No. 4) contains the following papers: 

 'On the Commutator Groups,' by Dr. G. A. 

 Miller; ' On the Limit of Transitivity of the 

 Multiply Transitive Substitution Groups that 

 do not contain the Alternating Group,' by Dr. 

 G. A. Miller; ' Geometry of Some DiflTerential 

 Expressions in Hexaspherical Coordinates,' by 

 Dr. Virgil Snyder ; a review of Lie's Difieren- 

 tial Equations, by Dr. Edgar Odell Lovett ; a 

 notice of Beman and Smith's translation of 

 Klein's Vortrage iiber ausgewahlte Fragen der 

 Elementargeometrie; 'Notes;' and 'Nevi^ Pub- 

 lications. ' 



The February Bulletin (Vol. VII., No. 5) is a 

 72-page number. It contains an account of the 

 recent annual meeting of the Society, by the 

 Secretary; an account of the Evanston meeting 

 of the Chicago Section, by Professor T. F. Hol- 

 gate. Secretary of the Section; the presidential 

 address, 'The Philosophy of Hyperspace,' de-
