Feeling the inconvenience of carrying a bag to hold dropper bottles when making a visit to eye patients, I have improvised a pocket case which will, in a measure, serve the oculist as the tablet case does the general practician. As may be seen in the picture, the case is an aluminum hypodermic case. Four of the tablet vials are used to hold solutions. Two droppers, one amber for atropin, are made by drawing out tablet vials in an alcohol flame. In the mouths of the droppers are fitted rubber bulbs from vaccine tubes, the perforations being closed with bits of rubber. The syringe hole carries a tube which may be used for another solution, or, as shown in the cut, an open tube, plugged in the middle with, a cork, may be used to hold two kinds of powder.
