AN ALVEOLAR SARCOMA

Mr. Roughton and the late Dr. Cosens. 1 These photographs are 

 reproduced in Figs. 33, 34, and 35. In the middle of Fig. 33 is one 

 of these intranuclear bodies x 800 diameters. There is an appearance 

 as of a vacuole in it, and it is seen to be provided with knobbed 

 tentacles, one of which has assumed a spiral form. Fig. 34_shows 

 a similar body. The tentacles at one end are attached to the nuclear 

 membrane, which is indrawn ; this feature was better seen in the 

 section than in the photograph. The third photograph (Fig. 35)

 amoeboid body with 'gemmule 5 formation.) 



shows, first, in optical section at a a large nucleus containing one 

 large and four small intranuclear bodies, and at b above and to the 

 right of the middle a free amoeboid body with the formation of 

 spherical ' gemmules '; some of the latter are seen to have fine peri- 

 pheral rays attaching them to the rest of the cytoplasm of the cell. 

 Some of the intranuclear bodies seemed to contain a circlet of bright 

 vacuoles, causing them to resemble very closely some of the intra- 



1 These photographs were made at the request of a society, with a view to 

 publication, in 1895, but they were not then published.
