 a thin clean cover glass placed lightly on top of the balsam. 

 Keep the slide in a warm place until the cover glass sinks 

 down flatly on the slide, and put the slide away for drying. 

 After drying for several days the balsam will become hard 

 and the slide may be cleaned with alcohol and the proper 

 label placed on the side. The label should contain the name 

 of the object, the thickness of the section, and the stain used 

 on one side of the cover glass ; and the name of the prepara- 

 tion and the date, on the other. Then put the slide away in a 

 slide box, properly labelled.
