hormone present in the transplanted fragments could have

A method for the successful transplantation of cortical tissue 

 in clinical cases is highly desirable. Unfortunately the trans- 

 plantation of all glands is still in the experimental stage. The 

 difficulty of obtaining healthy material for the transplant and 

 the desensitization of the recipient to the foreign tissue are the 

 two outstanding problems which must be solved before one can 

 hope for a successful general application of tissue grafting. 

 The great need and value of a method for transplanting corti- 

 cal tissue in man make it desirable that further studies in this 

 field be inaugurated.
