THE RELATION BETWEEN AMITOSIS AND MITOSIS.

width of the young ovary. In the five nuclei d, e,f, g, /there 

 can be no doubt regarding the occurrence of amitosis. Each 

 one of these nuclei was examined at all levels and in such cases 

 as f and g the membrane can be followed through the whole 

 nucleus. The. case indicated by b is one of those often found 

 where the two parts of the nucleus stain differently. At f the 

 two nuclei have apparently recently separated for they are nearly 

 hemispherical in form, their flattened surfaces are parallel and 

 closely approximated and are not visibly covered by cytoplasm. 



FIG. 7. 



The two nuclei at / are apparently also the products of a recent 

 division. The cytoplasm is still continuous on the upper side 

 and the nuclei are flattened on opposing faces. The figure also 

 shows one case of mitosis. 



Fig. 8, A, is from the same proglottid as Fig. 7. At this 

 stage muscle fibres are still visible passing directly through the 

 ovary and are indicated in the figure. It contains six cases of 

 mitosis, the largest number observed in any area of similar size. 

 But in this section are also two very clear cases of amitosis, (c 

 and z). The cases b, c, li and j are also undoubtedly amitoses 

 and several other nuclei in the figure are probably also dividing 

 amitotically. The number of mitoses in this section is of interest 

 since it exceeds so greatly the number seen in any/ other similar
