Tumours and other Tissues for Histological Examination 
In case of tumours, select from the edge of the new growth, and, if possible, include some 
of the adjacent healthy structure. Those parts of a tumour showing caseous or degenerative 
change should be avoided. 
As the nature of a tumour is often a question of the utmost importance, we must emphasize 
that it is not always in the power of the pathologist to give a positive answer as to the nature of 
the growth. In such doubtful cases the clinical characteristics are more important than the 
histological features. 
Method of sending material. — The most convenient way is to wrap the piece of tissue 
selected for examination in cotton wool moistened with weak spirit or 4 "/^ formol.
