able upper limit on the temperature of solu- 

 tions emanating from intrusive magmas. The 

 rare occurrence of wollastonite in eruptive 

 rocks was also discussed, and difficulties of 

 drawing conclusions as to the temperature 

 of their intrusion discussed, and the views of 

 Dr. G. F. Becker on the subject briefly cited. 

 An Area of Faulting in Central Pennsyl- 

 vania: Mr. Geo. H. Ashley. 

 The region described is one in which ex- 

 tensive mining operations have permitted the 

 mapping of a large number of faults and their 

 minute examination in many cases. The fea- 

 ture upon which most stress was laid was the 

 fact that the great majority of the faults run 

 in lines transverse to the general structure of 

 the region, and where the whole fault from 

 end to end has been found in a single mine 

 working, it appears to be of the nature of 

 a long transverse buckle, which is broken 

 down longitudinally. The resulting faults 

 have all the appearance of normal faults and 

 often present a much complicated series of 

 breaks with the intermediate blocks tilted or 

 dropped down, as is common with a broken 

 arch. The speaker's main argument was that 

 in attempting to account for the faults, re- 

 source must be had to the pressure which 

 folded the rocks of the region, their normal 

 appearance being due to the fact that unequal 

 resistance to that pressure allowed the buck- 

 ling of the strata in the lines of pressure, 

 which buckles or small folds afterwards broke 

 down to the positions in which they at present 

 are seen. Several charts were exhibited illus- 

 trating the features discussed.

THE KANSAS ACADEMY OF SCIENCE. 



The thirty-eighth annual meeting of the 

 society was held in Lawrence on December 1 

 and 2, with, over sixty members present from 

 different parts of the state. The address 

 of the retiring president, Professor L. C. 

 Wooster, was given on Friday evening on 

 ' The Development of the Sciences in Kansas.' 

 The academy was divided into two sections, 

 for reading of papers, of which sixty-five were 

 presented. Among those of more general 



interest, the following are noted: "A New 

 Repetition of the Foucault Experiments with 

 the Pendulum,' J. T. Lovewell; ' Some Eecent 

 High-efficiency Lamps,' R. H. Freeman ; ' Is 

 the Eain-f all in Kansas Increasing ? ' F. H. 

 Snow ; ' The Variation of Latitude,' E. Miller ; 

 ' Dry Periods in Northeastern Kansas, and 

 their Relation to Water Supplies,' W. C. 

 Hoad; ' Some Properties of the Alloys of the 

 Ferro-magnetic Metals, Considered from the 

 Standpoint of Osmond's Allotropic Theory,' 

 Bruce V. Hill; 'Note on Certain Formulas 

 for the Design of Reinforced Concrete Beams,' 

 A. K. Hubbard ; ' On the Substituted Ureas,' 

 F. B. Dains ; ' Chemical Reactions in Ben- 

 zene,' H. C. Allen; 'A Chemical Study of 

 the Lime-and-Sulphur Dip,' E. H. Shaw; 

 ' The Gas-and-Oil Engine for Commercial 

 Purposes,' P. F. Walker ; ' The Interpretation 

 of Transpiration in Plants,' L. N. Peace; 

 ' Indicator Diagrams,' C. D. Corp ; ' General 

 and Special Features of Laboratory Equip- 

 ment,' J. T. Willard; ' The Botanical Features 

 of the New U. S. Pharmacopoeia,' L. E. Sayre ; 

 ' The Loup Fork Miocene of Northwestern 

 Kansas,' C. H. Sternberg; 'Notes on Coleop- 

 tera,' W. Knaus; 'A Deep Well in Emporia,' 

 A. J. Smith ; ' A Little Experiment in Flower- 

 making,' Grace E. Meeker ; ' Hygroscopic 

 Structures in the Distribution of Pollen 

 Grains and Spores,' M. A. Barber ; ' Second- 

 ary Increase in Thickness of Smilax' W. C. 

 Stevens ; ' Notes oh the White Sheep,' L. L. 

 Dyche ; ' On the Malaria Mosquito and the 

 Relative Number in the Vicinity of Lawr- 

 ence,' S. J. Hunter ; ' Comparison of the 

 Microscopic Structure of Stems and Roots,' 

 C. M. Sterling; 'The Disintegration of 

 Cement Plaster under Peculiar Conditions,' 

 E. H. S. Bailey; 'The University of Kansas 

 Expedition to the John Day Region of Ore- 

 gon,' C. E. McClung; 'A New Qualitative 

 Test for Cyanides,' H. P. Cady. 



At the close of the session the following 

 officers were elected: 



President — F. 0. Marvin. 



First Vice-President — B. F. Eyer. 



Second Vice-President — J. E. Welin.
