124 A CYTOLOGICAL INVESTIGATION OF SOME SPECIES 
In the figure the gemini visible at high adjustment are drawn black, 
those apparing at medium adjustment dark-grey, while those at the lo- 
west level are drawn light-grey. Nearly all are adpressed to the nuclear

wall, as the drawing shows plainly.One sees that some gemini cover others 
almost completely; still all can be observed separately as they become 
visible at subsequent adjustments. In the picture two nucleoli are visible, 
one rather large, the other small; usually but one large nucleolus is pre- 
sent. The nucleolus can cause difficulty in counting, as occasionally chro- 
mosomes are so closely adpressed toit, that they appear as excrescences
