 Hanaman, C. E. — Filtering Wash-bottle, especially adapted to the use of the 

 Histologist. 



[A Woolff' s bottle, with tubes arranged as in a chemists' wash-bottle, so 

 that when air is forced into one tube the fluid is forced out of the other. 

 The first tube is provided with a rubber pressure-bulb for compressing 

 the air ; the second supports a filtering tube filled with cotton, so that 

 the reagent is always obtained free from suspended particles.]

[The solution is prepared by adding caustic potash to an alcoholic solution 

 of iodine till it becomes colourless, avoiding any excess of potash. It 

 should be greatly diluted.]

 leave someijiours to dry. 4. Remove the linen, add a few drops of 

 carbolic acid, drain it away after some minutes, dry carefully and slowly
