 ter from Joseph E. Muse, A. M., to the editor, dated Cam- 

 bridge, E. S. Maryland, April 3, 1833.) — I offer for solution in 

 your inestimable Journal, a philosophical problem of much intricacy, 

 the formation of three minerals, true oolites, (so I name them, not 

 from imaginary similitude, but real character,) in the body of a living 

 and health)'^ animal. 



At supper a few nights ago, on a dish considered in our section of 

 the country to be a great (although a very usual) luxury, the terra- 

 pin, ' Testud'o fluviatilis,' was boiled and served up, on the table, as 

 usual, with the shell unbroken. Having broken the shell of one of 

 the heaviest and fattest, though not the largest, I dissected the four 

 quarters and placed them over a lamp for dressing, and proceeded to 

 open the ovary, when, to my utter astonishment, I found three of the 

 eggs had turned to stone, which I now send you.
