follows: The tube should be from 9 to 10 Wehnelt, and a filter of 1 mm. of aluminum interposed; 0.75 of a pastille dose is given twice weekly up to a maximum of twelve doses, or until a slight degree of hyperemia shows itself. The skin may become "tanned” (see our editorial on “Actinotherapy,” in June WORLD, page 206), but at the first sign of reaction the treatment must be stopped for a week or two. If the condition of the patient and other circumstances permit there is no reason to delay the commencement of the treatment more than two or three days after the operation, and in treating cases of this kind we should not attempt to confine the rays accurately to the site of the operation, but allow as much as possible of the surrounding area to come under the influence of the irradiation.

After three months' interval, if all goes well, a further six applications are to be given, and again after a six months' interval.

If this procedure were carried out for two years in all cases, we should hear less of recurrences.

The great trouble is that post-operative treatment is not begun soon enough in a large proportion of cases, and in many of them deep extension has commenced, making all efforts to prolong life practically futile. There is not the least doubt that immediate post-operative X-ray treatment in carcinoma cases does definitely increase the patient's chance of making a complete recovery, and delay in applying this method not infrequently means that we are throwing away a victim's one chance of escape.

In no class of case is it more difficult to lay down definite rules for treatment; every case must be dealt with according to the conditions present. In most instances, the treatment will be more vigorous than stated above.

Full or even double pastille doses three times a week may be necessary for a time so as to produce a profound impression on the growth more or less quickly. If there seems to be deep extension, this is all the ore necessary, but here we must use a thicker filter-say 2 mm. of aluminum. The risk of dermatitis is very small when using such thick filter, but as we are giving massive doses we must act with all caution and discretion. On the other hand, only massive doses will be of any avail in a serious case, and we have to remember that if let alone the patient's life comes to an end in a short time; so that while we must not do anything to add to his sufferings thru X-ray dermatitis, we are justified in doing anything short of this that gives him a chance of escape or an extension of comparatively comfortable existence.

large indifferent negative electrode. A general anesthetic is required. There is coagulation necrosis or acid necrosis of the tissues for almost 1/2 inch around each metal point connected with the positive pole, and the portion of tissue thus destroyed dries up, and, eventually, after one or more weeks, separates, leaving a granulating surface.

Correct technic is extremely important. The indifferent negative electrode had better be a pad of kaolin laid over a smaller sheet of metal, which it more than covers. Any small area of metallic contact or markedly greater conductivity would permit a more concentrated Aow of the current, and produce, at the indifferent electrode, a negative burn, which is characterized by alkali necrosis or colliquative necrosis-a moist gangrenous process like that produced by the action of a caustic alkali. The patient is under the influence of an anesthetic, and so cannot give warning of the occurrence of a burn. The positive wire may be divided into about five strands, and it is best for the zinc points (pieces of sheet zinc, such as signs are painted on, about 14 of an inch wide at the base, about 3 inches long, and tapering to a very sharp point) to be soldered to the copper wires. If this is inconvenient, they may be bent around the wire and securely pinched. The points are galvanized by dipping them first in dilute acid and then in metallic mercury. The first point should be introduced before the current is turned on, and a rheostat should be used to very gradually increase the strength of the current from zero to 30 or 40 ma. Then another point is gradually introduced, and it will be found that the milliampere-meter registers an increased current, due to the larger area of contact. Other points are introduced so as to transfix the tissues all around, and, if practicable, beneath the growth. The current may then be found to be 50 or 60 ma., the increased area of contact at the metal points having greatly reduced the resistance at the positive pole, while the resistance at the negative pole has not been changed. Additional current is now turned on very gradually until 100 or even 200 ma. are indicated by the milliamperemeter. The flesh is seen to turn white, and a white froth exudes from the different punctures. The exact length of time that the current should be allowed to flow varies with the amount of tissue that is to be destroyed. It is usually between five and ten minutes. The current must be turned off just as gradually as it has been turned on, and the last metal point must not be removed until the current has ceased to flow. The 110-volt direct current is most suitable for the work. This may be obtained from the direct 110 volt electric light circuit, or from the alternating electric light circuit, by a rotary transformer, or a storage battery or a galvanic battery of the necessary number of cells to produce about 110 volts may be used.

This treatment has been applied to cancers of the breast and tongue, localities where turning the current on or off suddenly would cause serious shocks.

The advantages of this treatment are the freedom from hemorrhage, the complete destruction of the part to which it is applied, the presence of a sterilized and usually dry slough, which changes to a dry scab and comes away by natural processes. The disadvantages are that it does


Mercuric Cataphoresis in Treatment of

Cancer. The following description of the technic is taken from “Medical Electricity and Roentgen Rays,” by Dr. Sinclair Tousey* :

The term is usually applied to the method introduced by Massey. Extremely heavy currents of about 100 ma. or more are applied from the active positive electrode, consisting of sharp pieces of zinc amalgamated with mercury, thrust into the tissues while the patient lies upon a

not have a selective action upon the morbid tissue, nor one extending beyond the area actually destroyed, and that its cicatrizes are very bad compared with those left after a case has been cured by the x-ray or by surgical removal and a plastic operation.

While the method is certainly a valuable one for use in occasional special cases, it may not be unfair to characterize it in some other cases as an imperfect form of surgery. There is a ques. tion as to whether the destructive effect is at all due to the transportation of mercury into the tissues, or whether it is due altogether to the action of the electric current. The author feels that the latter is the chief factor in the case.
