Part III. The description of the figures will serve for 

 explanation. Sections stained as just mentioned faded 

 quickly, but H. and E. -stained sections are still well stained 

 after 28 years. 



It is to be noted that the tissue cells of this tumour are 

 ordinary connective-tissue cells. No epithelial cells were 

 seen in the parts of the gland that were affected by the 

 neoplasm. 



The peripheral processes of the intranuclear bodies 

 were seen in the H-E-B. -stained sections better than in 

 sections stained in other ways. They stained a brownish- 

 orange colour, and many of them were seen to possess knobbed 

 " tentacles " like that in Fig. 53, 2. In the haematoxylin 

 preparations the ends of these processes, being stained like 

 the chromatin, are not so clearly seen. 



Chromatin in and subdivision of parasites. In some 

 parasites, e.g. Fig. 54 ; 5, 6, and 13, chromatin is seen as it 

 had been streaming from the central part of parasites. 



In others the chromatin consists of a single central 

 mass, or several such. Spindles of the ordinary characters 

 are present in some of these cells, and simple binary division 

 of the chromatin mass, with or without formation of definite 

 chromosomes, may occur in them, as in similar cells of other 

 sarcomas ; but in this tumour the result of this form of 

 nuclear activity was limited to the formation of the small 

 roundish bodies shown in 8 and 16. The cells 9 to 19 are 

 described beneath Fig. 54. A few words as to the formation
