162 REV. H. G. W. AUBREY ON THE TURPENTINE BATH. 



not reach tlie bottom of the dish. This allows a space for any 

 grains of dirt which may gravitate downward from the vertical 

 position of the slide and object to float free of both, and when the 

 holder is lifted out it is at once clear of the sediment. Occasionally 

 it is desirable to empty the dish and run the turpentine through a 

 filter of blotting paper and return it. It is not necessary to use more 

 turpentine than will reach about half way up the slide when lying 

 in the holder. In the matter of space I do not see how the same 

 number of slides could be more conveniently packed. In my first 

 bath, measuring six inches by three and a half, I have now sixteen 

 objects suspended, with room for two or three more if I had more 

 holders. Any one of these I can at once withdraw from the bath 

 without disturbing the others, can place under the microscope, and 

 according as it seems ready for balsam or not, can shift for a 

 fresh slide to be put in soak, or replace in the turpentine. I shall 

 be glad if this bit of apparatus should prove of use to any member 

 of the society, I have reason, from extended experience, to think 

 it a really serviceable appliance.
