THE ARRANGEMENT OF THE LIVING MATTER 

 IN "PROTOPLASM."* 



THIS chapter was published in 1873, in German. Nine years 

 of continuous observation have corroborated all the facts 

 published, and I simply translate from the German what I said 

 in 1873. 



Amcelce. On watching a slowly moving amoeba, obtained 

 from an infusion, with high amplifications of the microscope 

 (1000-1200 diam. immers.), we see the following : In the body 

 of the amoeba is imbedded a globular, homogeneous, pale gray 

 nucleus. This is surrounded by a narrow light rim, which is 

 traversed by delicate grayish threads. Many of these threads, 

 often visible only temporarily, are conical ; all of them emanate 

 at their base from the nucleus, and have their point directed 

 toward the periphery of the amoeba. Each point blends with one 

 of the gray granules scattered throughout the body of the 

 amoeba. Many of the granules again are connected with their 

 neighboring granules by means of filaments, so as to convey the 

 impression that the amoeba is traversed by an extremely delicate 

 net-work, whose points of intersection are the granules. The 

 outer contour of the amoeba consists of a continuous thin layer 

 of a slightly shining substance, into which penetrate filaments 

 of the most peripheral granules.
