" CANCER-BODIES " IN SYNCH YTRIUM AND IN SYPHILIS 



Bird's-eye Nuclei in Synchytrium. In three species of 

 Synchytrium F. L. Stevens found nuclear structures the 

 nature of which, he stated in 1907, was far from clear: 



FIG. 24. SOME NUCLEAR PROCESSES IN SYNCHYTRIUM DECIPIENS. a, 

 Irregular nucleolus extending into the cytoplasm by radial extensions ; 

 6, group of bird's-eye nuclear bodies with an aster ; c, cluster of 

 bird's-eye bodies such as are often seen in cancer ; d, bird's-eye body 

 with aster attached ; e, mitosis, metaphase ; /, mitosis, anaphase. 

 After F. L. Stevens. From the " Lancet." 



' The structures were atypical, strikingly peculiar, and 

 quite without parallel in any plant or animal as yet de- 

 scribed." Some of these bodies are shown in Fig. 24, &, c, d. 

 The large nucleolus, Fig. 24, a, is continuous with the
