Having had the experience more than once of being routed out of bed after ten o'clock on winter nights to make journeys to the laboratory with diphtheria tubes to put into the incubator for early morning microscopical examination, and also of many an after-supper trip to see if any belated tubes had been dropped into the box prepared for them, it occurred to me that an incubator might be arranged so a tube in its containing case could be dropped into it from the outside of the building. I had a box so arranged, why not an incubator?
