4, Plate IV. Then it became transparent and moved 

 about quickly just like Amoeba radiosa. After a time it 

 assumed a figure like A. verrucosa (Leidy, Plate III, fig. 

 29). At this point I lost the thread of ray observation. 

 But looking at the gathering next day the amoeba were 

 all gone and empty shells of the cyclotella were left. 



Some Fine Points. 



The point of a pin (fig.l) can hardly be called a fine 

 point. It is very coarse when seen under a 1-5 objective. 

 That of a needle (fig. 2) shows a very much better work- 

 manship. Passing from man's handiwork to that of 

 Nature, that is to say from diluted to purer essence, we 

 get a very sharp point beautifully tapered in the rose 



thorn (fig. 3). Much more delicate and minutely drawn 

 out is the nettle sting (fig. 4) while the serrate and sharp 

 point of a wasp's sting exceeds all the rest in workman- 

 ship (fig. 5). Figs 1 and 2 represent mineral, 3 and 4 

 vegetable, and fig. 5 animal life, — the three great king- 

 doms of Nature in the first of which intelligence sleeps, 

 in the second it dreams, and in the third it wakes.
