HULTIN, J. M. T. Fil.lic. — Wenner-Grens Inst, for exper. Biol., Norr- 

 tullsgatan 16. STOCKHOLM 23, Sweden. 



a. Isotope studies of the nitrogen metabolism during early development. 

 (Echinoidea) 



b. Amino acid incorporation in vivo into the proteins of different cell 

 fractions from embryonic, adult, and regenerating liver and hepatoma. 

 Mus rattus (Rodentia) 



HUMMEL, Miss K. P, Ph.D. — Jackson Memorial Lab., Box 558, BAR 

 HARBOR, Me., U.S.A. 



a. Studies on the form and function of ovaries which have been grafted 

 into spleens of castrates and subsequently retransplanted into normal 

 position within the ovarian capsule of a normal host. Offspring of these 

 ovaries are examined for abnormalities which may be correlated with 

 the time the graft remained in the spleen. Mus musculus (Rodentia) 

 (in collaboration with C. C. LITTLE) 



b. Studies of early histological changes in ovaries that have been grafted 

 into spleens of castrated hosts. Correlation of such histological changes 

 with estrogen secretion by the graft. Strain differences in histology and 

 function of the grafts. Mus musculus (Rodentia) 



HUMPHREY, R. R. A.M., Ph.D., Prof. — Dept of Anat., School, of Med., 

 Univ. of Buffalo, 24 High Str., BUFFALO, N.Y., U.S.A. 



a. Studies on spontaneous haploidy and polyploidy. Amblystoma (= Sire- 

 don) mexicanum (Utodela) (in collaboration with G. FANKHAUSER) 



b. The offspring of polyploids; their chromosome number, mortality, pa- 

 thology etc. Amblystoma (— Siredon) mexicanum (Urodela) (in colla- 

 boration with G. FANKHAUSER) 



c. Matings especially of dark 2n X white 2n to obtain haploids (white) 

 to determine whether they are androgenetic or gynogenetic. Amblystoma 

 (= Siredon) mexicanum (Urodela) 



d. Triploid, tetraploid and other heteroploid females are mated with 2n 

 males, and the offspring studied. Amblystoma (— Siredon) mexicanum 

 (Urodela)

a. Development of descending root fibers of the trigeminal nerve in embryos 

 during 7.5 to 8.5 weeks age period. Morphological study based on 

 serially sectioned, pyridine silver impregnated embryos. Homo sapiens 



b. Pancreatic developmental studies. Homo sapiens (Primates) 

 HUNT, E. L. Ph.D., Prof. — Emory Univ.. Dept of Biol.. EMORY UNI- 

 VERSITY, Ga.. U.S.A. 



a. Studies on affects of various added materials, particularly carbohydrates, 

 on morphology of embryos. Gallus (Aves) 



b. Studies on the distribution of certain radio-isotopes in the embryo. Gallus 

 (Aves) 



c. Studies on the distribution of radio-iodine. (Amphibia)
