(1) The difficulty of staining Mycobacterium leprae in paraffin sections is due ( 1) to a capacity of the bacillus to adsorb paraffin wax, and (2) to destruction of its acid-fastness as a result of extraction with fat solvents. In both these respects this bacillus differs from the tubercle bacillus. 2.
