these points important results have been obtained. Besides the 

 bright red corona, there were only three protuberances visible, the 

 length and positions of which have been accurately measured. Of 

 special beauty and interest was one of the protuberances, distinguished 

 by a great length — (about 2 minutes, = Jth of the solar diameter). 

 Its color was an intense carmine red, and it remained visible not only 

 during the whole of the eclipse, but even one minute after it, when it 

 was obscured by clouds. On places where the edge of the disc of 

 the moon just covered the sun, appeared a beautiful red margin, being 

 separated from the sun by a narrow bright zone. The corona ex- 

 hibited in the appearance and arrangement of the various rays some 

 similarity to that observed on the 18th July, 1860, in Spain. 



The spectrum was not actually reversed during the eclipse, although 

 the dark lines perfectly disappeared, thus producing a faded, so called 

 continuous spectrum. A few seconds before the termination of the 

 totality, the color of the greatest refraction nearly entirely vanished, 

 while the bright red, the red and orange colors were quite sharp, the 

 yellow less distinct, and the green hardly perceptible. The red tints 

 remained visible with perfect distinctness and intensity ; they did not 

 pass into each other, being separated by clearly traceable dark lines. 

 To measure the width of each of the colored zones was impossible, 

 as the whole phenomenon only lasted from three to five seconds. The 

 duration of the eclipse was according to actual observation 2 minutes, 

 55 seconds, considerably shorter than in S. India, or on the eastern 

 coast of the Bengal Bay. 



The Austrian officers, during their stay at Aden, made numerous 

 other astronomical and meteorological observations, which will be pub- 

 lished in a special report of the expedition. Two meteoroscopes were 

 of great service, and by means of them the direction of the course of 

 about 200 meteors was determined. 



I may add that the photographers of the Prussian expedition who 

 remained at Aden, took with great success several views during the 

 eclipse. 



The President then requested Mr. W, T. Blanford, to favour the 

 Meeting with his 



Notes on a Journey in Northern Abyssinia. 

 At previous meetings of the Society, letters from me have been 

 read giving a brief general account of my movements in Abyssinia,
