114 DR. THOMAS ALCOCK ON THE 



canal ; a slight dilatation at the upper part showed the 

 incipient stomach. 



83rd day. Yesterday a young frog was taken from the 

 pond with a very small remnant of the tail. Today, on 

 looking round the borders of the pond, about half a dozen 

 young frogs were seen standing against the side with their 

 noses just out of the water. Their sight was very quick; 

 and on approaching them, they instantly swam away. 

 Two were taken out with the dredge, and placed in a basin 

 of water, where in a few minutes they became exhausted 

 and would have died drowned if not taken out. They 

 were placed on a saucer with a few drops of water, and 

 were covered with an inverted tumbler, up the inside of 

 which they immediately climbed and remained holding 

 on to the glass. They had each a small brown stump of 

 tail. 



The young frog taken yesterday, on which no vestige 

 of tail now remained, was examined. A drawing (83) 

 was first made of it, the natural size. The shape of the 

 body was strangely altered from that of the tadpole, the 

 abdomen being drawn in so that the animal appeared on 

 the verge of starvation. 



83 (2). On removing the skin from the ventral surface, 

 that over the abdomen was found to be loose and pale- 

 coloured 5 but the fascia beneath was purple and very 

 tightly bound down. The liver and alimentary canal were 

 removed in a mass and an enlarged drawing made of them. 

 The stomach was large, and widest at the cardiac end ; it 

 was placed across the abdomen close below the liver. The 

 intestine was very short, and made two or three turns ; it 

 was quite empty. The gall-bladder was large, and filled 

 with dark green bile. 



83 (3). The loops of the intestine were opened out, and 

 a second drawing made to show its whole length.
