is more advanced than the one at the lower pole. The two outer spheres 

 are not well differentiated. Oc. 2. 



32. There is a pcb. at each pole. The granosphere is everywhere violet. 

 In the upper pcb. it is cone-shaped, the archosome is moving upwards. The 

 centrosphere is pale white and very narrow. The somosphere is deep blue, 

 with darker centrosomes. The lower pcb. is much further advanced than the 

 upper one. The granosphere is starlike, and the centrosphere is more dis- 

 tinct than the one in the upper archosome. The upper archosome contains 

 three centrosomes, the lower one apparently but one. 



33. The pcb. are very large, but the inner spheres are not well differen- 

 tiated. In the upper pcb. (a) there is only one archosome, while in the lower 

 (b) there are three archosomes. Oc. 4. 



34. Two pcb., one at each pole. The one at the upper pole is more 

 advanced than the one at the lower pole. The centrospheres are white, the 

 somospheres blue, and the centrosomes dark blue. Oc. 4. 



35. There are two pcb., one at each pole. The granospheres are light 

 violet, the centrospheres deeper violet, while the somospheres are pale. In 

 the upper somosphere we see two separated centrosomes, while in the lower 

 one (b) they are too close to be distinguished. Observe the star-shaped cen- 

 trosphere at the upper pole, while the one at the lower pole is conelike. 

 The former is probably an indication of amoeboid movement. 



36. There are two distinct pcb., but only the upper one is of normal 

 size. This one contains three separate archosomes, each surrounded by a 

 concentrating granosphere, and each with a single centrosome. The lower 

 pcb. has spread out, enclosing about half the circumference of the nucleus. 

 In this lower pcb., also, the archosomes have separated, each having a single 

 centrosome. The pale spheres are probably centrospheres. The nucleus is 

 in fair preservation, showing a strong polarity. Ehrlich-Biondi. Oc. 3. 



37. This is a very large nucleus with a dissolving pcb. at the pole. 

 Probably the two poles have been brought together, at any rate, the appear- 

 ance is a very irregular one. There are three growing plasmocytes in various 

 stages of development. The lowest one is almost ready to separate as a fully 

 developed plasmocyte, containing apparently three archosomes. The young 

 plasmocyte to the left is the least advanced of all; the nucleus is in a high 

 state of disintegration and unusually swollen. Oc. 3. 



38a. In the fusiform corpuscle the lower pcb. has almost separated, and 

 the independent plasmocyte is all but ready. It is connected with the fusi- 

 form corpuscle by a long narrow shaft of plasmosphere. It contains two 

 archosomes, the lower one of which is much the larger. The granosphere is 

 narrow, and differentiated deep blue. The centrosphere is very large and 

 pale blue, containing a paler white zone with a few darker rays and a few 

 small central bodies. The large inner white zone is not easily explainable, 

 except as a part of the centrosphere. The dark round spot at the lower 

 margin is also of doubtful nature. The smaller archosome contains a distinct 

 centrosome. There is a residue of crescent-shaped granosphere at the lower 

 pole. The upper pcb. is probably dormant.
