III. HHIZOPODA. 
Reichert’s remarks on the morphological structure and the motory 
phenomena of the contractile^ substance of the Polythalamia (6r?wma ot;f- 
fot'mis) will be found translated in Ann. & Mag. of Nat. Hist. vol. xvii. 1866, 
pp. 351-359 (vide Z. Reeprd, 1865, p. 798). 
Under the heading of Kleinere Mittheilimgen, No. 1. Reichert und die 
Gromien,” Max Schultze criticises the statements of Reichert (Archiv f. 
mikrosk. Anat. Band ii. Heft 1, 1866, pp. 140-160). 
Reichert alludes to Max Schultze’s article in his own Archiv (Archiv fiir 
Anatomie &c., 1866, pp. 286, 287), and maintains, as before, (1) that what 
is called granular movement ” (Kornchen-Bewegung) in the pseudopodia 
of the Polythalamia is nothing but the result of a wave-like contractile motion 
(nichts Anderes als bine Contractions- Wellenbewegung ist), and that the 
so-called “Kornchen” are not really microscopical granules, but waves of con- 
traction (Contractionswellen) ; (2) that in his article on the subject of these 
“ granular movements,” even where the word ‘‘ apparent ” is not affixed, he 
has had in view the wave-like contractile movement, and not the motion of 
true granules ; (3) and, lastly, that, while he asserts the presence of true 
granules (Kornchen) in the contractile substance of other invertebrate animals, 
it is to be distinctly borne in mind that true granules are not known to him as
