340 W. ARCHER. 



In the living state he sometimes recognised noteworthy 

 alterations. In place of the firmer or coarser, darkly-shining 

 granules in the inner space, these not distinguishable from 

 those in the protoplasma, he noticed to occur a number of 

 large structures. These were roundish, sharply contoured, 

 by-and-by with a punctiform centre. This centre enlarges, 

 along with the body itself and shows itself as a cavity, appa- 

 rently filled with a hyaline substance ; they then have the 

 appearance of nuclei with comparatively large nucleoli, or 

 they might be taken for cells with several nuclei (fig. 12). 

 These " nuclei of the nuclei" (Kern-Kerne) grow consider- 

 ably, the inner cavity of the nucleus at the same time ex- 

 panding, until at last it bursts, the " nucleus brood" passing 

 out into the parenchyme of the Pelomyxa (fig. 12). Here 

 the inner cavity becomes more and more expanded, so that 

 finally the outer peripheral layer disappears, and then only 

 a simple, sharply contoured, hyaline, and shining body of 

 round figure has originated from it. This the author holds 

 to be the origin of the second class of bodies above men- 

 tioned — the " Glanzkorper" — and which are, he thinks, 

 probably to be regarded as the zoospores. 



These bodies, like the nuclei, but in still greater numbers, 

 are scattered in the inner parenchyme (fig, 11). They are 

 mostly globular, many also are oval, pyriform, or more rarely 

 irregular, even hollowed, lobed, or furrowed. The smallest 

 have a diameter of about 0'006 mm., the largest over 0'06 

 mm., the mean size, about 0'02 — 0'03 mm., being, however, 

 by far the most numerous. They consist of a solid shining 

 capsule, and usually completely hyaline and homogeneous 

 contents. Dilute acetic acid has little eff'ect, but under con- 

 centrated acid the peculiar shining appearance sooner or 

 later disappears, they lose their firm appearance and col- 

 lapse, and their contents become as if granulate. Alcohol 

 produces the same result. Iodine colours them intensively 

 brown. Sulphuric acid completely dissolves them. 



Although the author is most given to the opinion that 

 these bodies originate from the nuclei, as above mentioned, 

 he sometimes thought that they might originate direct from 

 the protoplasm, since he frequently saw these scattered in 

 numbers through the protoplasm, the nuclei around at the 

 same time perfectly unaltered. 



These bodies increase in the interior of the Pelomyxa by 

 means of dimsion. They are found biscuit-shaped, more and 

 more constricted, and the portions on the point of separating, 

 such divisions, however, not always dividing the body into 

 equal halves, but sometimes only a small portion being cut
