MICROSCOPY 73 



higher percentage alcohols usually take out some of the dye. The sections 

 are then again dehydrated, but a few drops of chloroform should be added to 

 the absolute alcohol so that the celloidin will not be dissolved. Two changes 

 in absolute alcohol and chloroform and then benzol to clear completely. The 

 sections are then mounted in balsam, making sure that they are completely 

 flattened out. A lead weight is placed on the cover slip and the slide placed 

 in a warm oven for 2 or 3 days. Thus the excess balsam may be pressed out 

 to allow the preparation to be examined with oil immersion.
