When using high-power objective use weak revolving nose-piece will be found very useful, since it issometimes necessary to change the objective on the samefield, and this insures a great steadiness of the object. Great cleanliness is needed in aU bacteriologic methods,but nowhere more so than in the microscopic examination. The cover-glass should be very carefully washed in alcohol,and dried with a soft hnen rag. To remove the stains on thecover-glasses that have been used they should be soaked inhydrochloric acid or placed in a 6 per cent, aqueous solutionof potassium dichromate with 6 per cent, of strong sulphuricaci
