482 Castration andThyroidectomy Basophils 



Conclusions 



The thyroidectomy and castration basophils of the anterior hypophyses of 

 the rat differ morphologically to such an extent that they may be used to 

 differentiate the pituitaries after these two types of operation. These differ- 

 ences are manifested in the size, shape, and distribution of the cells, also in 

 the mode of vacuole formation and in the distribution and fate of cytoplasm, 

 Golgi apparatus, and mitochondria.
