The last traces of fat are best removed from covers by 

 burning. The clean covers are placed on an 8 to 10 cm. 

 square piece of sheet iron, which is then heated for a few 

 minutes in the open flame of a Bunseu burner.

Author cleans slides and covers which have been used 

 with oil, Canada balsam, stains, etc., by first placing them 

 for a time in turpentine, separating the covers from the 

 slides as far as possible. They are then put into a broad 

 beaker, covered with hydrochloric acid, to which is added 

 a few grams (2 to 3 knife-points) of chlorate of potash. 

 This is then covered with a glass plate and heated on a 

 water bath for a few minutes. The glasses are then 

 washed in hot water. Equal parts of soda, talcum, and 

 sieved sawdust are now added with water enough to 

 make a thick fluid mixture, which is now heated for one- 

 half hour on the water bath, with frequent shakingof the 

 contents of the beaker. The glasses are then washed 

 again in hot water, to which a little hydrochloric acid 

 has been added, especially, in case some calcium carbon- 

 ate has been deposited on the glass. Finally wash in 

 hot water or ethyl alcohol and dry with a soft cloth.

Agar is slanted, in broad tubes (diam. 2-3 cm) The 

 material containing the bacteria is diluted to the proper 

 amount with sterile bouillon or water. The condensation 

 water is then inoculated by needle or loop, and subse- 

 quently tilted over the whole surface of the agar and 

 allowed to drain back again.
