Voted, That Dr. Wyman be requested to furnish a 

 copy of his noble tribute to the memory of the late Dr. 

 Warren, for publication and general distribution, in such 

 manner as the Council should decide. 



Dr. J. B. S. Jackson exhibited a remarkably tattooed 

 skin, taken from the body of a man supposed to be a 

 South Sea Islander. The coloring matter had been 

 examined by Dr. Bacon, and found to be carbon. The 

 same substance was seen in the inguinal glands. 



Dr. Pickering remarked that the natives of the Navi- 

 gator and Tonga Islands tattoo themselves in the same 

 manner; and possibly the man from whom the specimen 

 was taken may have belonged to one of those islands. 



Dr. C. T. Jackson presented a collection of mineral 

 concretions, composed of hydrated black-oxide of man- 

 ganese imbedding sand, in the form of globular or nearly 

 globular balls. The specimens were sent by William 

 Haley, Esq., of Tuftonboro, N. H. 



Dr. Jackson made some observations upon the forma- 

 tion of such concretions, as illustrating the manner in 

 which many of the ancient and fossil concretions may 

 have been produced. 



The remarks of Dr. Jackson elicited a discussion upon 

 the geology of the locality at Scarboro, Maine, and upon 

 the explanation of the formation of the concretions found 

 at that place, which was participated in by Dr. Gould 

 and Messrs. Bouve and Sprague. 



A letter was read from Mr. William Stimpson, sug- 

 gesting to the Society the propriety of memorializing 

 Congress upon the publication of a report, upon those 

 results of the recent North Pacific Expedition, which ap- 

 pertain to Natural History. A committee was appointed 

 for this purpose, consisting of the President, and Messrs. 

 Abbot, Gould, and Whittemore.
