PALEONTOLOGY — CASE, WiELAND. 23I 



Biochemisches Handlexicon, edited by E. Abderhalden, in which the impor- 

 tant characters of the different vegetable proteins is given in a concise form. 

 Grant 57J ($5,000). — Work under this grant was begun on April i, 1909, 

 and thus far has involved a continuation of the uncompleted investigations 

 begun under grant 497, which have been described in the account of the work 

 done under that grant.

Case, E. C, University of Michigan, Ann Arbor, Michigan. Grant No. 559, 

 Completion of zvork on the Permian reptiles of North America. (For 

 previous reports see Year Books Nos. 2 and 4.) $1,600. 



Since June 28 I have been in the American Museum of Natural History in 

 New York and will continue there until some time in September. Over 200 

 pages of manuscript notes have been prepared, and 109 pen drawings, which 

 will be increased to 130 or 140; also 35 photographs. The summer's work 

 will complete the review of the material in the American Museum. Succeed- 

 ing work will be upon the material in Chicago University, in foreign museums, 

 and upon newly acquired material. 



I have had the advantage of over a week's conference with Dr. Robert 

 Brown, of Victoria College, Stellenbosch, South Africa, the admitted author- 

 ity on the Permian reptiles of South Africa, and this has led to interesting 

 conclusions regarding the interrelations of the groups. 



There have been no preliminary publications as yet, but several will be 

 prepared during the coming winter. 



Wieland, George R., Yale University, New Haven, Connecticut. Grant No. 

 552. Continuation of investigations on American fossil cycads, and par- 

 ticularly for the preparation of a volume on "The Taxonomy of Ameri- 

 can Fossil Cycads." (For previous reports see Year Books Nos. 2, 3, 4, 

 6, and 7.) $2,000. 



Early in last year it was decided to extend the investigation of the fossil 

 cycads by engaging in the study of the plant-bearing horizons of the southern 

 portions of the continent. As nothing was known of the extent to which the 

 cycadeoidean florae might be represented in Central America and Mexico, it 

 was considered most opportune that the Geological Survey of the latter coun- 

 try had offered to share in these researches. Accordingly, field-work was 

 begun in western and southern Oaxaca March 3, and continued until July 20. 

 The results of exploration in this little-studied region have fully realized all 

 earlier anticipations. An accurate section has been made through a great 

 series of plant beds over 600 meters in thickness, and their Rhsetic-Liassic age 

 determined from the most extensive cycadophytean flora thus far found in 

 America. These horizons are not only of wide extent in Oaxaca, but are
