" From Coahuila many masses have been got, but it is ex- 

 tremely probable that all of them were brought from a single 

 district of very small area : the two Nuevo Leon masses have 

 never been examined and had obviously been transported, perhaps 

 from Coahuila or San Luis Potosi. 



" In Chihuahua three or four areas are represented : but of the 

 masses found in that State only those of the Huejuquilla group 

 have been examined, and that in a very incomplete way : the 

 recognition of the singleness of the fall of the Huejuquilla group 

 depends almost entirely on the general similarity of appearance 

 of the large masses. If the masses really belong to a single fall, 

 as the available information makes most probable, the maximum 

 dispersion is now 66 miles : but one of the terminal masses, that 

 of San Gregorio, is known to have been transported by the 

 Spaniards on one occasion for 1^ leagues, while according to a 

 tradition current three centuries ago it had accompanied the 

 Indians when they journeyed southward to take possession of 

 that part of Mexico." 



2. Kilaiiea. — A letter from Rev. E. P. Baker of Hilo, dated 

 Nov. 5th, speaks of Dana Lake, or a lake occupying essentially 

 its position west of the debris-cone in Halemaumau, as boiling 

 violently all over its surface, so that no crust remains upon it. 

 Jets consisting of successive clots of melted lava from three feet 

 to six, ten and even twenty feet in height were in constant play 

 over it. He had not seen the lake lava so hot at any time during 

 the past ten years. 



Mr. Maby, at the Volcano House, about two months previous 

 had reported that on Sept. 9th all activity in Dana Lake ceased, 

 and that there was an outbreak of lava in another place. But 

 three days later, the lake was again active and four other spots 

 in its vicinity had opened. 



3. University Studies / Published by the University of Ne- 

 braska. — This third number of a new and important series con- 

 sists of three papers : 1st, The determination of specific heat and 

 of latent heat of vaporization with the vapor calorimeter, by H. 

 N. Allen. 2d. The color vocabulary of children, by H. K.

4. Gesammelte Matliematische Abhandlungen ; von H. A. 

 Schwaez. — The very important Mathematical Contributions of 

 Professor Schwarz during the past thirty years, have been repub- 

 lished in two handsome octavo volumes by Julius Springer of 

 Berlin. The first of these volumes is devoted entirely to his 

 discussions of surfaces of minimum extent. The second volume 

 contains his various papers in Geometry, differential equations, 

 and other branches of the Higher Analysis.
