WATSON, Thomas L.— Continued. 



Gives results of studies of fresh and decom- 

 posed material along lines laid down by Dr. 

 Merrill, in his work on " Rocks, rock-weath-

The investigations were carried on in the 

 National Museum laboratories, and the speci-

 The writers were sent to North Greenland 

 by this Museum in 1897. An account of their 

 geological investigations is here published. 

 The lists of fossil plants are based entirely on 

 material collected by them. 



The Cretaceous and Tertiary formations of 

 Noursoak peninsula are described. Of sedi- 

 mentary deposits the thickness is not less 

 than 3,500 feet, capped by Tertiary basalts 

 attaining a maximum thickness of 4,000 feet. 

 The various localities and horizons for fossils 

 are described.

 This paper deals with art in prehistoric 

 times. It approaches the subject from the 

 aesthetic rather than the utilitarian point of 

 view, although the two are necessarily inter- 

 related. 



The introduction contains remarks on the 

 theory of art. 



The first and second chapters deal with all 

 kinds of art in the Paleolithic and Neolithic 

 periods, and with the differences in art be- 

 tween the two periods and the geometric or- 

 naments employed in both. 



The third chapter treats of prehistoric mu- 

 sical instruments, describing the gold and 

 bronze horns of northern Europe. This por- 

 tion of the work was prosecuted in collabora- 

 tion with Mr. E. P. Upham, whose musical

 meeting of the American Association for the

 Columbia University, New York City. 



Glass may affect the transmission of light 

 by reflection, by refraction, or by absorption. 

 The question discussed in this article is the 

 amount or proportion of light lost in passing 

 through glass of different kinds. Various 

 mechanical appliances were u.sed to deter- 

 mine loss: (1) a camera obscura, (2) compar- 

 ative photographs, (3) photometer.
