228* PROCEEDINGS OF THE BOARD OF REGENTS, 



when another of my brothers, Jesus M. Ainsa, visited Sonora and brought it 

 with him on his return. 



By the time of the receipt of this the aerolite must be already in "Washington, 

 as we delivered it to the agent of the Institute about a month ago, to have it 

 transported to you. Your agent spoke to us about expenses ; but we wish not 

 to deprive ourselves of the honor of having presented it to the Institute, and 

 as such we desire that you should accept it. 



I would be thankful if you would send me a copy of the analysis, and of other 

 informat : on about the aerolite ; and if you find it not too troublesome, to send 

 the same, with my compliments, to St. John's College, Fordham, New York, 

 where I was educated. 



I have the honor to remain, your obedient servant, 



SANTIAGO AINSA.

My Dear Sir: I send you a specimen of "cone-in-cone," which I have 

 lately obtained in sinking a shaft at this place upon the Harbor Vein seam of 

 coal described in Professor Lesley's report of this coal-field last year. 



It was found in the band that corresponds to the black bituminous shales 

 below the one inch of cannel coal, and 23 feet above the Harbor series of five 

 feet of coal. 



It was only obtained on the northwest side of the shaft, thinning out to the 

 south and east, or towards the "crop." The greatest thickness of the bed was 

 about 7 inches. The largest "cone-in-cone " was 5 J inches in diameter. 



The journal of the strata sunk through differs somewhat from Professor 

 Lesley's taken at the shore.

I cannot find in any work that I possess anything exactly like them, so 

 think they may be of interest to add to your museum. 

 The points of the cones are downwards.
