The need for a clean and neat apparatus for hot staining with carbolfuchsin has long been felt by laboratory workers in tuberculosis. With the advent of electricity and the use of nichrome wire for heating purposes, this want could be realized. Recently a good homemade "makeshift" electric hot staining apparatus was described by Carl L. A. Schmidt (The Journal, March 6, 1915, p. 823).
Since the opening of the Municipal Tuberculosis Sanitarium of the City of Chicago, there has been in use an electrical apparatus which is worthy of description, since it was found to possess manifold advantages over the older methods. By its use it was possible to fix the smears of sputum, etc., without danger of burning, stain them without danger of boiling the carbolfuchsin solution, and also avoid dropping carbolfuchsin all over the laboratory tables and floors. It was also possible to fix and stain as many
