To SHOW GANGLIA OF BLADDER. 



Eemove the bladder, empty it, and place in \ per cent,

 place it in water well acidulated with acetic acid, until 

 it has become swollen up to a good size, then preserve 

 it in glycerine.

GENITAL OEGANS MALE. 

 TESTIS. 



The best hardening fluid for the testis is undoubtedly 

 the chromic acid mixture. The organ is cut into small 

 pieces, or deep cuts made into it with a sharp razor, 

 according to the size. It must not be washed and 

 should be handled as little as possible. 



Sections are made in different directions through the 

 various parts, and it is advisable to make some large 

 sections through the corpus Highinori and globus major 

 to show the structure and relation of the different 

 parts ; some of these sections will show the epididy- 

 mis as well. These sections if at all large are very 

 difficult to mount, as they break to pieces on the lifter, 

 and it is often impossible to get them on to the slide 

 whole ; in this case the best plan is to use the cover 

 glass as a lifter, and clean it afterwards, when the 

 Canada balsam has set. 



Sections of testis are best stained in logwood, or 

 double stained in picro-carmine and logwood (page 86).
