 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 mouse. Offspring of 

 these ovaries are examined for abnormalities which may be correlated 

 with the time the graft remained in the spleen. Mus musculus (Mam- 

 malia) (in collaboration with C. C. LITTLE)

 logy, etc. Amblystoma (Siredon) mexicanum (Amphibia)

 in the spleen. Cavia cob. (Mammalia) (in collaboration with A. LIP- 

 SCHUTZ, S. BRUZZONE, Miss E. MARDONES and Miss M.
