THE AMERICAN MUSEUM JOURNAL 



The question is as yet quite unsettled, but as the "peridotite" 

 of Kentucky resembles the rock of South Africa, in which the 

 diamond has been found in such abundance, and the geological 

 relations are quite parallel, in a general way, between it and the 

 county rock, with those developed at Kimberly, the inference 

 seemed plausible, at least, that the diamond would appear, if 

 carefully looked for, in Kentucky also. 



There has indeed been some corroboration reported of this 

 suggestion, and at least two diamonds coming from Elliott County, 

 Ky., have been exhibited, though their absolute reference to 

 Kentucky is still in doubt. 



Finally, as permitting a greater degree of confidence in this 

 particular, the observation of Friedland may be quoted. He 

 showed that a fused globule of olivine — practically the rock 

 composing the Kentucky dikes — when stirred with a pencil of 

 graphite (carbon), upon cooling, was found to contain micro- 

 scopic diamond seeds or grains. 



The operations of the company will be watched with interest. 

 The specimens from Elliott County and a series from South 

 Africa are exhibited in juxtaposition in Case 25 (north end) in 

 the Mineralogical Hall. — l. p. g. 



THE NEW SEA-BIRD GROUP. 



Encouraged by the praise which has been so uniformly ac- 

 corded the " Bird Rock" Group, a companion group has been 

 prepared to represent the sea-bird life of a sandy beach. The 

 addition of a painted backgroiond not only increases the in- 

 structiveness of this new group by accurately depicting the 

 character of the birds' haunts, but also adds greatly to its 

 beauty and pictorial effect. The attempt to show many birds 

 in flight has also been surprisingly successful, skillful treatment 

 rendering the birds' means of support practically invisible. 



The locality represented is Cobb's Island, Virginia, a shell- 

 strewn, sandy islet seven miles long and about the same distance 

 from the mainland. This was formerlv one of the most remark-
