the academy of science op st. louis. 



At the meeting of the Academy of Science 

 of St. Louis on the evening of December 16, 

 the Nominating Committee reported a list 

 of candidates for the oiRces of the Academy 

 for the year 1902. 



A paper by K. K. llacKenzie and B. F. 

 Bush, entitled, 'The Lespedezas of Missouri,' 

 was presented by title. 



Professor F. L. Solden delivered an address 

 on the advance made in education during the 

 nineteenth century, stating that the most 

 characteristic feature of the century's pro- 

 gress lay in the epoch of expansion and organ- 

 ization which it marked. The influence of 

 Pestalozzi, Froebel, Horace Mann, William T. 

 Harris and other distinguished educators was 

 traced, the marked change in opinion con- 

 cerning the commercial value of education 

 brought out by the Centennial exposition of 

 18Y6 was indicated, and the establishment of 

 a true university grade in this country with 

 the opening of the Johns Hopkins University, 

 the year following, was commented on. 



Professor F. E. Nipher stated that he had 

 continued his experiments on the production 



of ether disturbances by explosions, and by 

 the motion of masses of matter. He had ap- 

 parently succeeded in eliminating the effects 

 of the shock of the air-wave upon the magnet 

 needle. The needle is adjusted to a condition 

 approaching niaximum sensitiveness. There 

 is no iron about the apparatus, except what is 

 contained in the needle and in the compen- 

 sating magnets. The latter are clamped in 

 place so that the structure on which they are 

 mounted may be pounded by a mallet without 

 disturbing the needle. Rowland effects due to 

 convection of electrified particles have also 

 been eliminated. There remains a marked de- 

 flection of the needle, seeming to indicate that 

 an ether distortion or wave originates in a 

 sharp or violent explosion. This result is so 

 amazing that it is announced with the state- 

 ment that the whole subject is yet under the 

 most searching examination. The coherer and 

 the receiver of the telephone are to be used in 

 two wholly different plans of experiment, in 

 one of which the effects along the entire track 

 of a leaden bullet are to be summed up in an 

 alternating current. The results which seem 

 to have been reached are in entire harmony 

 with the well-known experiment of Michelson 

 and Morley, who found that the ether within 

 the building in which they worked was being 

 carried along with the building and with the 

 earth in its orbital motion.

NORTH CAROLINA SECTION OF THE AMERICAN 

 CHEMICAL SOCIETY. 



The fall meeting of the North Carolina Sec- 

 tion was held on Saturday, November 23, 1901, 

 at 11 a. m., in the office of the State Chemist, 

 Agricultural Building, Raleigh, with presid- 

 ing officer, W. A. Withers, in the chair. 

 Eighteen (18) members and visitors partici- 

 pated in the meeting. 



After the reading and adoption of the min- 

 utes of the previous meeting and the transac- 

 tion of some minor miscellaneous business, the 

 following program was presented and dis- 

 cussed : 



'Notes on Instruction in Dyeing': G. S. 

 Fraps.
