ELEMENTARY DEPARTMENT, 



EIGHTH LESSON. 



"cleanliness is akin to godliness." 



QEALING AND CEMENTS.— The sealing of the cover-glass is 

 ^^ necessaiy when glycerin or any of its preparations are used as 

 mounting media. The reasons for this were given in the last lesson. 

 Though not necessary when gummy or balsamic media are employed, 

 it is often applied to them for ornamental or finishing purposes by 

 those whose tastes run that way. If the worker is not expert in the 

 use of balsam, and gets too much or too little in the mount, the 

 scraping away of the excess in the former case, or of the daub left 

 at the filling point in the latter, will not, however carefully done, 

 leave the most desirable results. In such cases, if the worker's 

 aesthetic proclivities are strong, nothing is better, after a careful 

 scraping and polishing with a drop of turpentine — taking care not 

 to allow it to eat under the cover — than the application of a ring of 

 the medium employed, be it gummy or balsamic. This the writer 

 has found not onlv tasty but durable.
