238 REPORTS ON INVESTIGATIONS AND PROJECTS. 



Mr. J. W. Hornbeak has made an exploration of the infra-red absorption 

 spectra of certain of the iiranyl salts for the purpose of determining whether 

 the remarkable group of absorption bands existing in the visible spectrum 

 repeats itself in some region of longer wave-lengths. His measurements, 

 which were made with great care, using a Nichols radiometer, indicate the 

 absence of such absorption in the infra-red spectra. It is probable, therefore, 

 that fluorescence in the infra-red is likewise absent. 



PHYSIOLOGY. 



Reichert, E. T., University of Pennsylvania, Philadelphia, Pennsylvania 

 Grant No. 700. Study of differentiation and specificity of homologous 

 vital substances. (For previous report see Year Book No. 9.) $1,500 



The research has been confined almost solely to the starches, with results 

 in entire support of the hypothesis underlying the hemoglobin research. The 

 experimental portion of the investigation will be completed within the next 

 four or six weeks; the results of the investigation (with the exception of 

 the final chapter and a few additions and alterations in other chapters) are 

 typewritten and ready for the printer, and the photomicrographic work is 

 about four-fifths done. It is expected to have the manuscript ready for 

 presentation before the first of the coming year. 



POLITICAL SCIENCE. 



Rowe, L. S., University of Pennsylvania, Philadelphia, Pennsylvania. Grant 

 No. 633. Study of federal system of Mexico. (For previous reports 

 see Year Books Nos. 8, 9.) $1,500 



Under a grant for the year 1910, a study of the federal system of Mexico 

 was begun. During a stay in Mexico four chapters of this investigation 

 were completed, covering the following: 



Chapter I. The basis of the Mexican Federal system antecedents of the Constitu- 

 tion of 1857. 



Chapter II. The provisional organic Law of 1856, and the Constitution of Febru- 

 ary 5, 1857. 



Chapter III. Amendments to the Constitution of 1857. 



Chapter IV. Organization of the Federal Government ; Relative position of the 

 Executive, Legislative, and Judicial Authorities. 



In June 191 1 Dr. Rowe returned to Mexico to continue the investigation, 

 but for this purpose no further grant from the Institution was requested. 

 The purpose of this second visit was to collect material for the following 

 chapters : 



Chapter V. The constitutional position of the States ; Political influence of the Fed- 

 eral Government in the States. 

 Chapter VI. Constitutional guarantees in the Mexican political system. 

 Appendix. Documents illustrative of the Constitutional development of Mexico.
