All who have occasion to work with, the ordinary forms of 

 zoophyte trough are aware of the difficulty and the risk of 

 breakage there is in cleaning them, more especially with the 

 shallower forms. 



The apparatus shown above is designed with the view of 

 overcoming this difficulty. 



Fig. 13 is a plan view of the trough with the cover removed, 

 Fig. 14 a similar view of the cover, and Fig. 15 a longitudinal 

 section of the trough through the centre of figure 13.
