creased, when combined with carbonate of ammonia, andadministered in a diluted condition. The decoction of sar-saparilla is an excellent vehicle, and is in itself useful as atonic. The iodides of sodium and ammonium are inferior, inMr. Lane’s opinion, to the iodide of potassium ; but whenthe latter disagrees, and produces dryness of the throat,headache, and coryza, they may be substituted for it withadvantage, as they are certainly not so liable to be attendedwith these unpleasant effects. Mr. Lane has not met with acase in which one or other of the iodides could not be borne,if the dose at the commencement was sufficiently reduced-and in some cases it has been found necessary to make it assmall as half a grain,-when carefully, and by slow degrees,toleration will be established. In all cases the gradual in-crease of dose is a point of great practical importance. It isby persisting in the same dose that the good effect is oftenmissed, that disappointment ensues, and the remedy is dis-credited.Mr. Lane is not prepared to offer any explanation of the

mode in which iodide of potassium acts so beneficially intertiary syphilis. It is known to be a diuretic, but it cannotbe on this that its influence depends. It is also known toact as a solvent for some metallic substances which mayhave become incorporated in the tissues, of lead for ex-ample, and, there is good reason to believe, of mercury.Hence its innuence in causing salivation, as it not unfre-quently does, when first given to those who have taken toolarge doses of mercurials. In this way it may prove bene-ficial by getting rid of mercury which has been given inexcess, or persevered in too long. But it is not, he thinks,only from their antagonism to mercury that the iodides arebeneficial in tertiary syphilis, for their effects are equallymanifest when no mercury at all has been given, and alsoin those cases in which the tertiary stage sets in, as itsometimes does, without having been preceded by thesecondary. Whatever may be its mode of operation, it isfound to be the most powerful of all stimulants and tonicsfor persons who labour under the cachexia of tertiarysyphilis. The outward symptoms disappear under its use,the health improves, and in the end, in most cases, per-manent recovery is the result. The fact that salivation issometimes induced when the iodides are given at the end ofa mercurial course has, Mr. Lane believes, given rise to theidea that it stimulates and rouses up the mercurial influence,and hence has arisen the custom of prescribing it in

secondary affections, after mercury has been discontinued.He does not agree with this practice, although he knows itis a very common one. If mercury has been given at theproper time, and has not been given in excess, it is betterto leave it to do its own work, than to complicate mattersby following it with a remedy which is antagonistic to it inits action, and which is inappropriate to that particularstage of the disease.Mr. Lane has rarely found the iodides of any service in

purely secondary affections. He believes that, on the con-trary, they will almost always be found injurious in theearly stages. From their stimulating properties they tend toaggravate skin affections, and especially to irritate dis-ordered mucous membranes. If from any cause it is thoughtadvisable to abstain from mercury in the early secondarystage, it is a mistake to suppose that the next best thing isto give the iodide of potassium.From what has been said, it may be inferred that Mr.

Lane is not in favour of the combination of mercury withthe iodides in the treatment of syphilis, although the prac-tice is frequently adopted. A very favourite method is togive the perchloride of mercury in combination with theiodide of potassium in secondary affections. The result is,of course, a solution of biniodide of mercury with iodide ofpotassium in excess. This appears to be 11 blowing hot andcold " at the some time, since the one remedy tends to neu-tralise the effect of the other; and, in most cases, wherethe one is necessary the other is injurious.

If there are any cases in which such a combination isdesirable, it would appear to be those which are passingthrough the transition period between the secondary and Itertiary stages, when the symptoms partake somewhat ofthe cbaracter of both periods—when, for instance, there !,nre patches of scaly or papular eruption coincidently withdisease of periosteum and bone, with recurrent iritis,chronic enlargement of the testis, or gummatous swell-tegs.

CHARING-CROSS HOSPITAL.

A CASE OF PRIMARY CANCER OF THE LIVER.

(Under the care of Dr. HEADLAND.)

FoR the following notes we are indebted to Ivfr. Palfe,registrar.Carcinoma of the liver, being usually preceded by cancer

of other organs, is rarely met with as a primary affection.As a secondary deposit its occurrence is far more frequent;and Rokitansky has estimated that it is found once in theliver for every five instances of its presence in other partsof the body. The difficulties of diagnosis in the presentcase were increased by the absence of icterus, ascites, oroedema, and by the want of any distinct evidence of indu-rated protuberances in any part of the organ. In summingup the features of the case, Dr. Headland remarked thatthe enlargement could scarcely be attributed to cirrhosis,since there was no history of alcoholic intoxication, nor toalbuminoid disease, as there was no evidence of caries,long-continued suppuration, or of either of the other usualcoexistent conditions; abscess of the liver and hydatid cystwere excluded from consideration by the absence of pyrexiaand of any circumscribed tumour; and, taking into con-sideration the rapidity of its growth and the presence ofpain, he concluded that the enlargement must be due eitherto cancer of the stomach and secondary deposit in the liver,or, in spite of its rarity, to primary cancerous infiltrationof the latter.W. S-, aged forty, was admitted into the hospital on

the 12th of January, suffering from enlargement of theliver. He stated that for the last three months he hadbeen gradually losing flesh and suffering from obscure painsin the right side. He always previously considered himselfa strong, healthy man, and had never lost a day’s workthrough sickness. Six weeks before admission he had beenseized with sharp cutting pains, which made him feel sick,and compelled him to leave his work and go home. Sincethen he had been laid up. He had always been a temperateman, and had never had syphilis. There was no history ofcancer in his family. He complained of constant pain,aggravated by every movement, and by the slightest touch.There were complete anorexia, and occasional vomiting; onceor twice blood had been observed. The bowels were consti-

pated and the motions clay-coloured. The urine had a specifiegravity of 1027, and yielded a violet-coloured abnormal de-posit on cooling. The area of liver dulness could be traceddownwards to a line drawn from the umbilicus to the cristailii on the right side, and to a line drawn from the umbilicusinto the left hypochondrium to the region of splenic dul-ness. The percussion of the upper border gave the follow-ing limits :-In the mammary line, dulness just above theupper margin of the fifth rib; in the axillary line, to thesixth rib ; and in the dorsal line, to the upper border of theseventh rib. Palpation of the edge of the liver afforded nodefinite information, though there were a suspicious hard-ness and tenderness in the epigastric region; otherwise theliver felt uniform and smooth. Bronchial breathing washeard over the base of the right lung. The case remainedunder observation till the 3rd of February, when the

patient died. A few days before his death he becameparaplegic.On examination after death, the body did not present any

distinct cachexia, nor was there oedema or ascites. On open-ing the abdomen, the liver at once came into view, reachingdownwards below the umbilicus, and studded with largewhite excavated patches of the size of a crown-piece; these,towards the margin, were less distinct, and the liver-tissuewas more equally infiltrated and less nodular. On section,the liver was studded throughout with circumscribed tu-mours of medullary cancer, some of which were undergoingsoftening. The weight of the liver was 9lb. 5 oz. Thebase of the left lung was consolidated. The bladder wasdistended with urine; its mucous membrane much pig-mented and eroded, owing, no doubt, to the alkaline urinesecreted since paraplegia had come on. Careful search wasmade in the stomach, intestines, and lungs for other de-posits, but these organs were, without exception, quitehealthy.
