44 A MANUAL 



Take a tumbler and place a circle of card inside 

 it, just below the edge, cut a round hole in the centre 

 of the card, and stick two or three circles of pins, 

 heads uppermost, on the card's upper surface and as 

 close to the glass as you like. Here is a model of 

 an Anemone, rough certainly, but sufficiently ac- 

 curate for our purpose. 



That part of the tumbler which touches the table 

 corresponds with the base of the live animal, the 

 outside of the glass with its body, and the edge of 

 the tumbler therefore with the margin of the body. 

 The whole of the upper surface of the card repre- 

 sents the oral disc [" disc," a flat circle ; " oral," 

 round the mouth]. 



The hole in the centre is the mouth ; draw a line 

 round it, and it will include the lips. The circles of 

 pins are the circles of tentacles, and their heads 

 represent the tentacle heads. 



That is clear enough : now for the inside of 

 the animal. In Plate II., fig. 4, is a section 

 of a full-grown specimen of the "thick-skinned" 

 anemone. At b is the outer skin, stretching from 

 one margin of the body, round the base, to the 

 other margin : a a are the tentacles, situated on the 

 oral disc which terminates at d, the mouth, and be- 

 low d is the stomach, which some of your specimens 

 are sure to protrude for your inspection at some 

 time or other, so I need not describe that. 



The so-called "ovaries'' lie coiled round the
