. British bee journal & bee-keepers adviser. Bees. July I, 1874.] THE BRITISH BEE JOURNAL. 37 the bottle to rise up to the top of the tube, where, coming into contact with the steam jet, it is simplj' pulverized and blown forward in the form of spray. The instrument was in- vented to blow medicated spray down the human throat, and, as is often the case with scientific machines, its operation being once observed, it soon rendered itself necessary for other purposes. The steam spray as it leaves the glass tube, being directed against the bulb of a thermometer, raised the mercury to 146° Fahr.; we, therefore, tried it against the sinu- ous web of the wax-moth in an old comb, and found it answer exceedingly well; the white worms, where able to do so, making their exit to the other side of the comb, where, to use our assistants' expression, ' they hung gasping.' We have not tried the effect of the spray upon combs affected by foul brood, but do not see why they should not be rendered perfectly sweet and wholesome by its means. We do not go so far as to expect the restoration of combs containing the actual rotten brood; but we do not see why those from which the re- mains of the brood have been removed, or which are simply infected thi'ough being in a foul-brood hive, should not be perfectly dis- infected. The rotten brood woidd, of course, require the disinfecting agent to be thoroughlj'- incorporated with it, which it is not professed the spray produced will do ; but where simple surfaces only require the application, the ma- chine will do its work well. The cells of a comb are formed of simple surfaces, yet it is most difficult to bring them into contact with a disinfectant by washing, or immersion, they seem too small to allow liquid to get in to drive the air out of them, and the air in them form- ing one globule, fits the cell too tightly to lift itself out through the liquid in which the comb may be immersed.
