224 E. E Howell — Meteorite from Puquios, Chili. 



upper side, wliich was probabl} T the forward portion during 

 the latter- part of its flight, but the iron although very little 

 oxidized shows none of the characteristic stride and ridges seen 

 in irons that have recently fallen. 



The amount of troilite found in cutting the iron is not great, 

 and seems to be all distributed in comparatively thin narrow 

 plates, no nodules having been seen. The largest example is 

 6 inches in length and less than J inch in average thickness, 

 with an unknown width of certainly over 2h inches. It is 

 quite irregular in outline and terminates at one end in a star 

 with points about |- inch long. This form, which is very sug- 

 gestive of certain crystallizations of marcasite, seems to be quite 

 persistent, showing substantially the same in different sections 

 for 2^- inches without any indication of coming to an end, any 

 more than the plate with which it is connected. 



The Widmanstatten figures are brought out with remarkable 

 quickness on the application of very dilute acid, and are sur- 

 passed in beauty by no iron with which I am familiar. They 

 resemble somewhat the markings on the Trenton and Mum- 

 freesboro irons, but more closely those of the Descubridora. 

 The lines are thinner, however, and the inclosed figures smaller 

 and more elongated, being in many parts a mere thread 5 to S mm t 

 in length. In this respect different parts of the same section 

 vary greatly. Some of the inclosed figures are beautifully 

 marked with the fine lines noted by Dr. J. Lawrence Smith 

 first on the Trenton iron and called by him Laphamite mark- 

 ings. 



The analyses of this and the following iron have been kindly 

 furnished by Mr. L. G. Eakins of the TJ. S. Geological Survey, 

 through the courtesy of Professor F. W. Clarke, chief chemist.

2. The Puquios, Chili, Meteorite. 



This iron was purchased by Professor Ward from the wife 

 of Enrique Eavenna at Copiapo, Chili, April 26th, 1889. 

 According to Seiiora Eavenna's statements it was found by her 

 husband four or five years before — probably in 1884, near 

 Puquios, and had been kept by them until secured for the 

 Ward and Howell collection.
