 bladder backwards and- press the infero-lateral surfaces downwards and

 when its surface has been sponged the mucous lining and the orifices may 

 be examined, and the relations of the base may be investigated. If it is 

 necessary the anterior border may be divided vertically from the apex of 

 the bladder to the upper border of the prostate
