ChaptiBR IV. — The Reform Laws: 



A brief consideration of these laws is necessary, as they constitute an inte- 

 gral part of the constitutional struggle between the church and the state. 

 The material for this chapter is in hand, but has not as yet been co-ordinated 

 for final writing. 



The remaining chapters of the monograph for which material must be 

 collected are: 



Chapter V. The organization of the Federal Government. 



Chapter VI. The division of functions between Federal and State governments. 



Chapter VII. The constitutional position of the States. 



Chapter VIII. Constitutional guarantees under the Mexican Constitution. 



Appendices : 



1. Bibliography. 



2. Documents illustrative of Mexican constitutonal development. 



PSYCHOLOGY. 



Franz, Shepherd Ivory, Government Hospital for the Insane, Washington, 

 District of Columbia. Grant No. 80. For investigation of the functions 

 of the cerebrum, with special reference to the functions of the associa- 

 tion areas. (For previous reports see Year Books Nos. 4, 5, 6, and 7.) 



$1,000. 



During the year work on the functions of the parieto-occipito-temporal 

 lobes has been continued with satisfactory progress. New work on the rela- 

 tion of the occipital lobes to visual sensations and perceptions has also been 

 in progress and a preliminary account of the findings will be published shortly. 

 In connection with the investigation of the functions of the cerebrum, special 

 tests and observations on the intelligence of monkeys were made under my 

 direction by Mr. William T. Shepherd, and the account of the results of the 

 various experiments and observations is almost ready for the press. 



No publications pertaining to the grant have been made during the year. 



ZOOLOGY. 



Castle, W. E., Harvard University, Cambridge, Massachusetts. Grant No. 

 562. Continuation of experimental study of heredity in small mammals. 

 (For previous reports see Year Books Nos. 3, 4, 5, 6, and 7.) $1,000. 



The increased grant for the current year has made possible the enlarge- 

 ment of breeding experiments with small mammals, which were already in 

 progress, and the undertaking of desirable new lines of experimentation. 



The experiments with rabbits have been directed chiefly toward a more 

 precise determination of the laws of inheritance of size and of proportions of 

 parts, matters which the experiments of previous years had shown to be not 

 in conformity with Mendel's law of heredity. Some unsolved problems of 

 color-inheritance have also been given further study.
