THE Chief Health Officer desires to draw attention to the careless way in which some medical practitioners forward sputum for microscopical examination to the Laboratory, Public Health Department, and suggests that such material should be sent in strong glass-stoppered bottles. This would obviate any danger of contamination, and do away with the risk incurred by the Bacteriologist’s assistant when opening pill-boxes, ointment-tins, &c. containing tubercular and other dangerous matter.
