326 PROCEEDINGS OF THE AMERICAN ACADEMY 



Professor Agassiz stated that, during his recent visit to 

 Switzerland, interesting discoveries had been made in a rail- 

 road cutting on the shores of Lake Neufchatel, and in the bed 

 of the lake, at a period of unusual lowness of the water, of 

 a quantity of Celtic utensils, along with the remains of many 

 animals not existing in the vicinity, or even in Europe, at the 

 present time. Among them were stone hatchets, closely 

 resembling those of the North American Indians ; and other 

 implements with handles made from the horns of the Euro- 

 pean deer, now extinct in that vicinity ; also, bones of the 

 wild boar, which now exists only in the eastern and northern 

 parts of Switzerland ; and, in other places along the shore, 

 remains of pottery, bronzes, &c., indicating several different 

 social states at different periods. 



Professor Gray communicated the Diagnosis of the Species 

 of Sandal-ivood ( Santalum) of the Sandwich Islands : — 



The species of Santalum inhabiting the Sandwich Islands are of 

 considerable interest, inasmuch as they furnish the celebrated sandal- 

 wood, formerly exported from those islands in considerable quantities, 

 and not yet exhausted, though the supply is much diminished. 



Although gathered long ago by Menzies, Santalum Freycinetianum 

 and S. ellipticum were first made known and imperfectly discrimi- 

 nated by Gaudichaud. Hooker and Arnott afterwards proposed a 

 third species, & panicidatum, which is evidently no more than a va- 

 riety of S. Freycinetianum growing in drier or more exposed places. 

 Indeed, it is questionable whether S. ellipticum is not likewise a mere 

 variety of that same species, so polymorphous in foliage, of which 

 Gaudichaud's S. Freycinetianum, as figured in the Botany of Frey- 

 cinet's Voyage, is probably the most narrow-leaved form. For the 

 present it may suffice to give such diagnoses as I am able to draw up, 

 fi'om the examination of a full suite of specimens, of these two species, 

 if such they be, and of a third and more distinct species, well marked 

 by its larger drupe with a strongly rimose or ruminated putamen, 

 which was discovered by the naturalists of Captain Wilkes's Expe- 

 dition on the island of Kauai.
