 studied with the electron microscope. (Aves and Mammalia) 



MASUDA, H. — Lab. of Embryol. and Exp. Morphol., Zool. Inst., Dept of 

 Sci., Kyoto Univ., KYOTO, Japan. 



a. Behaviour of phosphor in early development. Triturus pycrhogaster 



b. Induction in regenerating blastema. Triturus pycrhogaster (Amphibia) 

 MASY, S. — Inst. d'Anat., Univ. de Louvain, 38, Rue des Recollets, LOU- 

 VAIN, Belgique. 



a. Experimental analysis of the development of the appendicular skeleton 

 in the chick embryo. (Aves) 

 MATHER, W. B. M. of Sci. — Zool. Dept, Univ. of Queensland, George 

 Str., BRISBANE, Queensland, Australia, 

 a. Superimplantation in the rabbit. Oryctolagus cuniculus L. (Mammalia)

 on reproduction. Mus musculus (Mammalia)

 and dibenamine. Mus musculus (Mammalia) 



McCALLION, D. J. B.A., M.A., Prof. — Dept of Biol., Acadia Univ., 



WOLFVILLE, Nova Scotia, Canada, 

 a. Effects of carcinogens on growth, regeneration and differentiation in 



frog larvae. (Amphibia) 

 McKEEHAN, M. Dr — Dept of Zool., Univ. of Chicago, CHICAGO 37, 



111., U.S.A. 

 a. Cytological and electronmicroscopic studies on lens induction. Gallus 



(Aves) (in collaboration with P. A. WEISS and R. PETZOLD) 

 McKENZIE, J. Ph.D. — Univ. of Colorado, Med. Center, Dept of 



Pediatrics, 4200 east Ninth Ave, DENVER 7, Col., U.S.A. 



a. Study of differentiation of chick somites in explants (Spratt technique), 

 (Aves) (in collaboration with H. HERRMANN, L. LUBCHENCO 

 and U. ROTHFELS) 



b. Study of developmental disturbances related to nutritional deficiencies 

 investigated by application of anti-vitamins and anti-amino acids to the 

 intact egg and to explants (somites). In particular, it will be attempted 

 to define the factors which maintain the balance between myotome, 

 sclerotome and dermatome during differentiation of the somite and are 

 required for the normal development of the retina (possible connection 

 with retrolental fibroplasia of the premature human infant). (Aves) 

 (in collaboration with H. HERRMANN, L. LUBCHENCO and U. 

 ROTHFELS)
