tinged with red before their liberation. When Hberated they 

 present a star-like form. This form I in some instances noticed 

 them to have while within the parent corpuscle. Before becoming 

 star-like, they present about half-a-dozen segments; each 

 segment sends out a cilium, and hence the star-like form. Such 

 corpuscles are seen slowly revolving, and even performing loco- 

 motion. They are also seen effecting changes in their form — 

 struggling, as it were, in order to separate into parts, each part 

 or segment bearing its cilium. After such separation the ciliated 

 segments exhibit extremely vivid motions. But these are far 

 from being the minutest red corpuscles met with in the same 

 blood. Many are seen not exceeding in size the separated 

 segments just mentioned, but star-like in their form. [May 

 not these arise from the segments in question, which are nuclei, 

 performing self-division ?] Lastly, there are other bodies so 

 immeasurably small as to appear as mere points. They have 

 precisely the same red colour as corpuscles of larger size, and 

 exhibit most vivid motions. I believe these to be no other than 

 separated and ciliated segments of the /a^^-mentioned generation 

 of star-like corpuscles. 



Such then was the account I published at the time mentioned, 

 of this self-division of red corpuscles of mammiferous blood. It 

 may be asked : Where do such self-divisions end ? Who will 

 say that exudation corpuscles and all that the blood deposits for 

 nutrition or the formation of new parts, are not nuclei thus 

 derived from corpuscles of the blood ? 



Where does the formation of cilia cease ? Who will say that 

 spermatozoon-like blood-corpuscles, of a minuteness that no 

 magnifying power can reach, do not escape the vessels, sculled by 

 cilia through the pores ? 



XL VIII. On the Magnitude of Galvanic Polarization, 

 By W. Beetz*. 



THE experiments of Lenz and Saweljew have demonstrated 

 that the polarization of a platinum plate by means of chlo- 

 rine is nearly equal to zero, whereas I have found that the elec- 

 tromotive force of platinum and chlorine in a gas battery is more 

 than half as great as the force of platinum and hydrogen, and at 

 the same time it was manifest that the effect produced upon a 

 charge already established, by agitating the platinum electrode 

 covered with chlorine, was to increase the current. As the mea- 

 surements of the Petersburg physicists are vitiated by numerous 

 sources of error, I instituted new experiments, and thereby deter-
