It is always desirable, when operating on external hemorrhoids, to see that quite a goodly portion of the cutaneous surface, especially at the summit, is effected by the preparation applied inside the capsule; otherwise it will become inflamed in order to let out the interior coagulum, which I have often seen come out on the third day intact, and in one unbroken cystic-looking mass, Fig. 5. The same rule obtains regarding internal hemorrhoids, having thick, unyielding coats. Puncture the tumor at the most accessible point, preferably with the needle, nearly parallel with, or at an acute angle to its base, carrying the point of the needle to about the center of the tumor, if it be globe shaped, or equi-distant from base to apex, if it be elongated, with the face or opening of the needle toward the apex. Be sure the needle is inserted beyond the proximal end of its opening, which is not always observable in treating small growths; but may be tested by forcing the piston of the syringe a little, and if the end is not sufficiently buried the medicine will show around it on the outside. Inject the first few drops the same as you would a hypodermic of morphia, then slowly, drop by drop, watching its action by change of color on the surface of the pile. This change of color on the surface is quite marked with hemorrhoids of delicate covering, less so with those possessed of more tough and fibrous coats. Hold the needle in position a moment and if the quantity injected does not appear sufficient, turn the nut on the piston with which you have previously gauged approximately the quantity to be injected, back a few rounds and throw in more. Puncture large elongated tumors in two, three, or four places. The compound diffuses itself slowly and no doubt extends some farther than is always apparent at the time of operation. Withdraw the needle carefully; it may be necessary to force out a few drops of the preparation at the point of entrance, for the purpose of sealing up the puncture to prevent the escape of blood and medicine together, which, however, never amounts to much. If, after withdrawing the needle, some of the injection fluid runs out, unmixed with blood, take it up with absorbent cotton, since it indicates that the quantity at that particular part is superfluous. Now dry the surface of the tumor or tumors with absorbent cotton, smear with vaseline and return within the bowel. A tumor properly injected immediately becomes hard. There are septa or compartments in elongated growths which do not permit the medicine to pass through readily, and if a soft section is noticed, it has not been penetrated, although will doubtless break down with the general mass. I have seen a liberal injection into the middle one of three tumors connected and arranged in a row, so cut into those on either side that a single reddened column like appeared afterwards on the extreme outside, (Figs. 6 and 7).
