' A Comparative Study of the Leaves of Lo- 

 lium, Festuca and Bromus,' by Emma Pammel. 

 In Festuca tenella the bulliform cells are want- 

 ing, while well developed in Lolium perenne 

 and but slightly in Bromus racemosus. 



' Anatomical Study of the Leaves of Certain 

 Species of the Genus Andropogon,' by C. B. 

 Weaver. In the species studied there appeared 

 to be characters of specific value. 



' Some Anatomical Studies of the Leaves of 

 Eragrosiis,' by C. E. Ball. In this genus the 

 anatomical characters appear to be insufficient 

 for specific characterizations. 



' The Uses of Formaldehyde in Animal Mor- 

 phology,' by Gilbert L. Houser, discussed the 

 peculiar properties of this reagent, its disad- 

 vantages and the advantages in its use in cer- 

 tain fixing agents and its value in neurological 

 work. 



'The Nerve Cells of the Shark's Brain,' by 

 Gilbert L. Houser. Morphological value, gen- 

 eral features of structure and results attained 

 by use of the Golgi method. 



' Some Manitoba Cladocera,' with description 

 of one new species, by L. S. Ross, included 

 notes on the author's collecting and the de- 

 scription of a new species of Ceriodaphnia. 



The same author presented papers on ' A 

 New Species of Daphnia and Notes on Other 

 Cladocera of Iowa,' and a description of ' The 

 Illinois Biological Station.' 



Mr. Charles Carter remarked upon ' The 

 Odonata of Iowa,' and requested specimens and 

 correspondence relating to the insects of this 

 order, with a view to presenting a complete 

 catalogue of the'species of the State. 



' Notes on the Orthopterous Fauna of Iowa,' 

 by E. D. Ball, lists the known species of the 

 State and includes remarks on distribution and 

 life histories. 



'The Ophidia of Iowa,' by A. H. Conrad, 

 calls attention to the desirability of a study of 

 the State fauna before many of the species be- 

 come entirely extinct. The author desires ma- 

 terial for study. 



' Contributions to the Hemipterous Fauna of 

 Iowa,' by Herbert Osborn, gives a list of about 

 100 species not hitherto recorded for the State, 

 and notes on the life histories of certain spe- 

 cies. 



The following papers were read by title : 'Ver- 

 tical Kange of Fossils at Louisiana,' by C. R. 

 Keyes and R. R. Rowley, and ' The Probable 

 Life History of Urepidodera cucumeris, by F. A. 

 Sirrine. 



In business sessions the Academy adopted 

 strong resolutions against the passage of anti- 

 vivisection laws for the District of Columbia^ 

 voted a contribution to the Pasteur Monu- 

 ment Fund and elected the following ofiicers for 

 the ensuing year : President, W. S. Fi'anklin j 

 First Vice-President, T. H. MacBride ; Second 

 Vice-President, B. Fink ; Secretary-Treasurer, 

 Herbert Osborn ; Elective Members of Execu- 

 tive Committee, L. S. Ross, J. L. Tilton and 

 C. O. Bates.

 HOPKINS UNIVERSITY. 



The one hundred and thirtieth regular meet- 

 ing was held January 21, 1897, Vice-President 

 Howell in the chair. 



The papers presented and read were : 

 The Stratification of Olaciers and the Origin of 

 Some Moraines: By Harry Fielding Eeid. 

 Observations were begun last summer to deter- 

 mine the actual direction of the motion of the- 

 ice of the Forno glacier in Switzerland. They 

 will be completed next summer. The vertical- 

 as well as the horizontal components of the mo- 

 tion in different parts of the glacier will be deter- 

 mined. This is to test a theory published in the 

 Journal of Geology, Vol. IV., p. 913, in which 

 it is shown that the vertical component of the 

 movement should be downward above the n6v6-^ 

 line and upward below it. If this is true, then- 

 material dropped from the clifis in the reser- 

 voir of the glacier should disappear and emerge 

 again at the surface below the neve-line. Such 

 moraines were found and were seen to be inti- 

 mately connected with the stratification. All 

 the observations on the Forno glacier indi- 

 cate that what Forbes called the ' ribboned 

 structure ' is, as Agassiz contended, the out- 

 crop of the strata. The very bad weather last 

 summer interfered so much with the work that 

 this conclusion could not be finally confirmed 

 or disproved.
