Dissection of Newt and Salamander. 59 



DISSECTION OF NEWT AND SALAMANDEK. 



Kill a newt and cut off the head, fix it to the table 

 on its back, by a needle passed through the neck and 

 another through the tail. Make a longitudinal incision 

 down to the anus, take up the upper end of the 

 stomach with a pair of forceps, and by carefully cutting 

 away the connective tissue attaching it to the cavity, 

 the whole of the contents of the body can be removed 

 en masse. 



Cut away the lungs and liver, which are not wanted. 

 Make an incision through one side of the stomach in its 

 whole length, and then put the whole in solution of 

 chromate of ammonia. In Triton cristatus there will 

 generally be found in the male, two testes on each side, 

 but sometimes three or four ; some of these may be re- 

 moved for the purpose of making a fresh preparation 

 of Spermatozoa. 



Salamander is treated in the same way for the same 

 tissues.
