MEETING OF THE NEBRASK.^ ACADEMY OF 

 SCIENCE. 



The twelfth annual meeting of the Nebraska 

 Academy of Science was held the 24th and 

 25th of January, 1902, at the University of 

 Nebraska, Lincoln, Nebraska. 



The President's address, given by Professor 

 E. W. Davis, was upon the subject, 'The 

 Numerical Basis of Induction'; the remainder 

 of the program being composed of the follow- 

 ing papers : 



'A Method of Instruction in Crystal- 

 lography,' by Professor E. H. Barbour, in 

 which he described an original method of in- 

 struction by the use of paper models to illus- 

 trate the extension of the faces; and plaster 

 of Paris models, to allow of cutting in various 

 planes, in which may be imbedded 'strings 

 to show the position of the axes. He also 

 showed apparatus for casting the latter. 



'Preliminary Notice of a Bacterium Asso- 

 ciated with Apple Rot,' by Mr. P. J. O'Gara, a 

 review of experiments tending to show that 

 rotting of apples is due to bacilli hitherto un- 

 described. 



'Some New Properties of Conies,' by Dr. 

 Carl C. Engberg, in which he ilkistrated some 

 new facts bearing upon the transformation of 

 well-known curves into other curves in accord- 

 ance with certain assumed conditions. 



'Report of Progress of the Nebraska Geo- 

 logical Survey': Professor E. H. Barbour. 



'The Quadrat Method in Phytogeography,' 



by Dr. P. E. Clements, in which the author 

 described the way in which this method was 

 applied and gave some curious results of an 

 attempt to estimate plant population under 

 certain conditions. 



'A New Bat Parasite,' by J. C. Crawford, 

 Jr., being a description of a new genus and 

 species belonging to the family Hippoboscidae 

 which has hitherto only been reported in 

 North America from New Mexico. 



'The Fossil Bryozoa of Nebraska,' by Pro- 

 fessor G. E. Condra, in which he stated that 

 the total number of species known for the 

 State was 51, of which a score were hitherto 

 undescribed. 



'On a New Form of Psychrometer,' by Mr. 

 John Fossler, in which he described a form of 

 psychrometer in which the thermometers were 

 rotated about a' vertical plane with such a 

 small radius that the apparatus could be used 

 in a very limited space without at the same 

 time any loss in accuracy. 



' New Bird Lice from Nebraska ' : M. A. 

 Carriker, Jr. 



'Notes on North American Bees': J. C. 

 Crawford, Jr. 



'Nebraska Water Mites': Dr. R. H. Wol- 

 cott. 



The last three papers were entirely sys- 

 tematic, containing descriptions of new 

 species, together with records of occurrence, 

 and in the case of the last paper also a table 

 for the separation of species and such biolog- 

 ical data as would present a complete view of 

 what is known of the hydrachnid fauna of 

 the State. 



' Some Observations on the Buried Rock 

 Surface of Eastern Michigan': Dr. C. H- 

 Gordon. 



'On the Use of Closed Aquaria in School- 

 rooms,' by Professor Haven Metcalf, in which 

 the author also gave hints on %vhat could be 

 grown, where and how to gather it and the 

 best methods of cultivating the same. 



'Some Remarkable Fossil Shark's Teeth 

 from Nebraska,' by Professor E. H. Barbour 

 and Carrie Barbour, in which the authors 

 called attention to some teeth of Campodus 

 and other sharks much more perfectly pre- 

 served than any hitherto found.
