    and 6 respectively; and a third probe, having a bulb tv sizes larger than No. 6, which I have called No. 8 T]l| bulb of No. 8 is of the size of the ordinary ware gauge No. 1 } These bulbed probes are curved in one plane onl the narrow part above the bulb allowing them tcT] in, and m some degree to adapt themselves to, the irr gular course of the nasal duct. The bulbed probes 1 fin perhaps from habit, more easy of introduction than Bov man’s, and 1 think they give less pain to the patient, prefer Bowman’s larger probe when any considerable pressui is required to overcome an obstruction, as the direction j the pressure can be made thereby more vertically, and mow m the axis of the nasal duct, than by the bulbed probes which are curved only in one plane. After the probe It* been once passed through the nasal duct, the treatment i usually very simple. The probe may be passed a secon. time, if necessary, at the end of a week, and may be repeats weekly, or at progressively increasing intervals, as long a the epiphora continues to relapse. On first adopting thi treatment I used the probe every second or third day; bul finding the frequent repetition unnecessary, and perhap injurious, I have been gradually led to allow longer inter to elapse between each operation. In my earlier cases I used the styles with the endi tapered, and bent at a right angle, formerly suggested, bu generally laid aside, by Mr. Bowman. These were introducec through the divided canaliculus into the sac and nasal duct and allowed to remain for periods of four, eight, or twelvi hours. They appeared, however, to retard progress by thf irritation which they caused. Since the publication of Mr. Bowman’s paper in November, 1857, in which he advised the “ intermittent use of probes,” I have never had recourse- to these bent ones, though exceptional cases may occur in which they may prove of service. When a patient has been free from epiphora for a month.
