as the light of day the errors about the sarcode,” Reichert 
concentrated his annihilating attack, after many devious 
windings, in the following assertions: — (1) The pseudopods 
are solid contractile threads which never ramify; (2) these 
threads never blend together by true anastomosis, (3) there- 
fore the threads can never be bound together by mem- 
branous dilatations ; (4) the granules in the pseudopods are 
“ loops which oscillate along the surface of the threads under 
the appearance of granules.” Let us now compare these 
separate assertions with his latest exhaustive treatise, which 
was to establish them in every point. 
(1) The ramification of the pseudopods. — According to 
Reichert’s former assertions this never occurs ; and the appa- 
rent ramification arises “from the dissolution and loosening 
of a bundle of pseudopods.” Now he asserts the contrary 
i.e., that ramification of the pseudopods really occurs, which 
is caused by a contractile motion ! 
(2) The anastomosis of the pseudopods. — According to 
Reichert’s former assertions this never occurs, and the appa- 
rent union is caused by the superposition of free threads or 
apparent branches. Now he asserts the contrary, i.e., that 
true anastomosis occurs in the pseudopods, since the pseudo- 
pods “ themselves grow together with similar portions in a 
short time under the appearance of uniting !” 
(3) The flattened dilatation of the pseudopods. — According 
to Reichert’s former assertions this never occurs, and the ap- 
parent formation of web-like sarcode dilatations of the anasto- 
mosing pseudopods arises from “ the pseudopods crossing at 
an acute angle and nearing each other, or, more properly, 
bundles of pseudopods separated into their different threads 
being moved from their place and squeezed together at the 
angle under the appearance of a layer.” Now he asserts the 
contrary, i.e., that true dilatations occur in the pseudopods, 
and that “the web-like expansions of the contractile substance 
in the sarcode-net become interposed from a portion of the 
contractile substance from which pseudopods are developed, 
maintaining its connection with the remaining portion of 
the contractile outer layer only by a fine pseudopod-like 
thread !” 
(4) The granular movements of the pseudopods. — According 
to Reichert’s former assertions no granules whatever exist in 
the sarcode, and the apparent granules are “ oscillating loops 
of the threads !” Now he asserts the contrary, that actual 
granules are present besides the apparent ones, and that these 
last are “ very small, wart-like elevations of the contractile 
substance.”
