e became exceedingly skillful and was quite faithful. We
believed that the best results were obtained in a seance of two or three
minutes, the finger tip being used over the lid, and the surface of the
cornea lubricated with a drop of pure olive oil, although in glaucoma
the addition of the oil is not necessary. Four movements were utilized,
the first a stroking movement in lines radiating from the central
pressure, very much as the spokes of a wheel radiate from the hub,
second a circular movement, third a pressure movement, a little dipping
motion, so that the cornea was slightly depressed, and finally, a gentle
tapping movement, precisely the same, except that it was a diminutive
one, as the tapping movement that the Swedish masseur makes. Usually
each movement occupied from a half to one minute, according to the
results desired. I agree with Casey Wood that such a technic furnishes
just as good results as any one with the aid of an instrument.

Referring particularly to the reduction of intra-ocular tension, many
surgeons have been impressed with the value of various instruments.
Thus, Ohm, who has worked particularly in the reduction of the increased
tension of secondary glaucoma, for example, after discussion of lamellar
cataract, advocates the Piesbergen instrument, which makes 3,000
vibrations a minute, and is applied over the closed lids. I think the
instrument best known is the one introduced by Malakow. For this purpose
the point of an Edison electric pen is armed with a small ivory ball,
and the vibration rate varies from 200 to several thousand a minute, the
rapidly revolving ball being passed over the closed lids, in some
instances directly upon the cornea itself. I am frankly afraid of these
vibrating machines, and again make a plea for the finger tip, just as I
am afraid of a Von Hippel trephine, and prefer one which is rotated with
the fingers.

A special investigation of pressure massage according to the method of
Domec has been made by Paul Knapp of Basel. This, as you know, consists
in applying the thumb to the cornea through the closed lids, and making
repeated pressures upon it at the rate or 60 to 100 a minute. He checked
his results with the tonometer after 200, 500 and 1,000 pressures, and
found that even in normal eyeballs such massage was followed by a fall
of intra-ocular tension, the average being nearly 9 mm. after a thousand
pressures. Within three-quarters of an hour the tension returns t
