REACTIONS OF THE SPOTTED NEWT 191 



of meat, it half swallowed a piece of filter paper, but imme- 

 diately disgorged it. It then seized and swallowed a piece of 

 meat. 



Two days later it followed and seized but immediately dropped 

 a piece of yellow cloth; it then paid no attention to a roll of 

 black cloth, but snapped a piece of meat when offered it. 



The second animal was tested with the same small pieces of 

 paper, cloth, etc. When offered the roll of filter paper, it fol- 

 lowed it about in the aquarium quite actively, finally seizing and 

 half swallowing it, but immediately disgorging. It then seized 

 and completely swallowed a piece of white raw cotton, after 

 which it refused to follow either black or yellow cloth, and 

 only followed the meat after some coaxing. 



Two days later it followed a piece of meat and snapped at 

 it so suddenly that it was seized and swallowed before it could 

 be withdrawn. It then seized and half swallowed a piece of 

 filter paper, but disgorged it. A piece of filter paper soaked in 

 meat juice that was now offered, was seized and swallowed; this 

 filter paper was disgorged and was found in the aquarium two 

 days later, at which time the animal followed and snapped at 

 a roll of yellow cloth, but after once seizing it, refused to follow 

 it again ; a piece of meat that was now offered was followed and 

 snapped at again and again, but was withdrawn each time 

 before the animal could get it. A piece of black cotton which 

 was offered was seized, but immediately disgorged. It now 

 refused to follow a piece of white parraffin, but tried to seize 

 a piece of meat when it was offered. The paraffin was seized 

 by another animal, but was immediately dropped. 



A third animal was tested in the same way as has just been 

 described for the first two and acted in essentially the same 

 way. It would follow small tasteless objects of various colors 

 and would often seize them, but usually disgorged them almost 

 immediately. Usually after snapping at the tasteless objects a 

 few times the animals refused to follow them longer, but in 

 such cases they would nearly always follow and try to seize 

 a piece of raw meat of the same size. The color of the tasteless 

 objects seemed to make little or no difference in the reaction. 



Generally after swallowing one good-sized piece, whether of 

 meat or of one of the indigestible objects, the animal could not 

 be induced to touch anything more at that time.
