REPORT OF THE PRESIDENT, 1914. 31 



determining epochs and periods in the evolution of Roman con- 

 struction, and hence in the evohition of Roman history. In the 

 aUied field of Roman paleography Dr. Loew has published, 

 through the Clarendon Press, Oxford, a volume of researches 

 under the title, ''The Beneventan Script; A History of the South 

 Italian Minuscule." The extensive researches in embryology 

 carried on under the direction of Professor Mall, with the collabo- 

 ration of a number of associates, have proved highly productive, 

 as shown by the publications issued and in press. Similarly, 

 attention may be called to the fruitful studies of Dr. Osborne 

 and Professor Mendel, which promise to throw important light 

 on the intricate physico-chemical processes of animal nutrition 

 and growth. The older sciences of chemistry and physics have 

 made not less important progress through the contributions of a 

 dozen associates and many more collaborators. A very note- 

 worthy advance has been secured in meteorology by Professor 

 Bjerknes through the international adoption of his methods and 

 units for expressing meteorological data. Beginning with this 

 calendar year and continuing up to the onset of the European 

 war, the United States Weather Bureau issued daily weather 

 maps of the whole northern hemisphere in conformity with these 

 new^ methods and units, greatly to the advantage of theoretical 

 and applied meteorology. The comprehensive and always highly 

 suggestive expositions in geology and in cosmogony for which 

 Professor Chamberlin has long been distinguished have stimu- 

 lated his colleagues, Professors Michelson, Gale, and Moulton, 

 to the production of a capital contribution to geophysics in an 

 ingenious and conclusive proof that the rigidity of the earth is 

 about the same as that of steel. And finally, in illustration of 

 the ease of passage from one field to another in this complex 

 miscellany of independent researches, there may be cited the con- 

 cordances of the earlier poet Horace and the later poet Spenser, 

 now in press as numbers 202 and 189, respectively, of the Insti- 

 tution's series of publications.
