The Microscope. 11 



sheaths shown in Figs. 8 and 9 happened to select such whim- 

 sical patterns, when the typical form that should have been 

 produced is exhibited in Fig. 10, which is the empty loricse of 

 Salpingmoa Steinii, S. K. The species forms characteristic 

 rosette-like clusters on algal filaments or fine leaflets, and it 

 was within such a cluster that these two malformations were 

 observed. It may readily be imagined that the lorica of Fig. 8 

 shows the impress of an impinging fibre, a thread of alga, or 

 other delicate filament, around which the plastic, growing lorica 

 was forced, and that the one shown in Fig. 9 grew up between 

 four parallel and superposed vegetable fibrils, which left the 

 indelible mark of their roundness in the soft structure. But 

 these are guesses only. Nothing more explanatory than a guess 

 was to be found in the vicinage. 



Although so plentiful that they often encrust the support- 

 ing object until the surface is completely obscured, the mem- 

 bers of the Choano Flagellata, the collar monads, possess a 

 charm that never palls, a grace that is always elegant, and a 

 shapeliness always bonnie. They are beautiful even in de- 

 formity.

CYCLOSIS. 



A MICROSCOPIC LYRIC. 



We were watching for cyclosis 

 In a Tradescantia-cell, 

 -Where the protoplasmic wave seemed loth to flow; 

 Though we sought by endosmosis 

 The clear sap therein to swell, 

 And to start the denser fluid to and fro. 



We but moved the mirror slightly, 

 The adjusting-screw a thread, 

 The reticulating lines were plainly seen; 

 In the nucleus shone brightly, 



Granules white and granules red, 

 With the lesser granules bobbing up between. 



What was that? A little quiver 



Seemed along the edge to stray —
