the British Museum. This meteoric-iron contains, according to an 

 analysis of Mr. Turner, 93.4 iron, 6.618 nickel and 0.535 cobalt. In 

 the reign of the Spaniards the manufacture of meteoric-iron "was not 

 permitted, in consequence of which but little attention has been 

 given to this important subject. To Mr. Bliss belongs the credit of 

 having brought it to the attention of the government and the scien- 

 tific world. 



The foregoing forms but a short sketch of the present known geol- 

 ogy of the Argentine Republic which I had intended to present to 

 the Society. But I hope that the many railroads which are" being 

 built at present, particularly through mountainous parts of this 

 Republic, will afford the means of increasing our knowledge of the 

 geology and paleontology of this country, as they have of Europe, 

 Asia and North America. 



Mr. Edward Pickering, Dr. C. F. "Winslow, Messrs. C. J. 

 Sprague, R. C. Greenleaf, and W. H. Mies were appointed a 

 committee of nomination, and were requested to present at 

 the next meeting, a candidate for the office of President, 

 made vacant by the resignation of Professor Jeffries Wyman.
