The summit of Grewingk was generally invisible 

 from the clouds of steam which issued from many 

 points of its surface, but no crater seems to exist. 

 A sort of fissure existed in the south-west side, and 

 two or three different pinnacles could be seen at the 

 top when the wind drifted the steam away for a 

 moment. Some of the jets of vapor were steady, 

 others intermittent. No noise accompanied the ejec- 

 tion of steam. The cone is composed of very differ- 

 e n t materials, 

 most of which 

 seem to have 

 been upheaved 

 from the sea-bot- 

 tom; such as 

 large bowlders, 

 blocks of sand- 

 stone, small 

 pieces of shale, 

 etc., all more or 

 less covered with 

 sand and fine 

 pumice-ashes, in- 

 to which one 

 sank to the depth 

 of a foot or 

 more in attempt- 

 ing the ascent. 

 No lava was seen, 

 nor any cindery 

 rock. The as- 

 cent was checked 

 by the heat of the 

 ashes, and the 

 clouds of sulphu- 

 rous steam, at a 

 height of about 

 two hundred 

 feet. The stones 

 about the jets 

 exhibited incrus- 

 tations of iron 

 and sulphur; the 

 latter forming 

 large dendritic 

 masses of a 

 greenish color, 

 which, at a little 

 distance, looked 

 like vegetation. 

 The north-east 



slope of the cone was steeper than the south-western 

 one, but more regular. 



The Bogosloff peak was alive with sea-fowl and 

 sea-lions, but was destitute of vegetation. It showed 

 no signs of volcanic activity. The volcanic ash ex- 

 actly resembled that which fell at Unalashka Oct. 20, 

 1883, and the latter doubtless came from Bogosloff 

 Island. The island, in its new form, is about a mile 

 and a quarter in length, and half a mile in extreme 

 width, trending north-west and south-east by com- 

 pass. The Corwin will visit it again on her return 

 from the north in the autumn. 



NOTES AND NEWS. 



The editor has received an acknowledgment 

 from Dr. Anton Fritsch of the money forwarded to 

 him, as already announced in Science, on behalf of 

 American geologists toward a memorial tablet to 

 Barrande. This tablet has been erected, at a cost of 

 more than six hundred florins (of which 175.60 were 

 sent from America), on a cliff at Kuchelbad, and is 



represented i n 

 the accompany- 

 ing illustration 

 from a photo- 

 graph sent by 

 him. Dr. Fritscli 

 returns his best 

 thanks to the 

 American donors 

 in the name of 

 the natural-his- 

 tory section of 

 the Prague mu- 

 seum, and says 

 that the publica- 

 tion of this proof 

 of sympathy has 

 made a deep im- 

 pression upon 

 his countrymen. 

 The list of Amer- 

 ican subscribers 

 was printed in 

 Vesmir for July 

 1. From the 

 same paper we 

 learn that the 

 Barrande fund 

 for researches in 

 the Silurian for- 

 mation of Bohe- 

 mia has reached 

 4,200 florins.
