As regards the mode of proceeding, the following are useful rules: Ascertain, if possible, the existence of fluctuation; locate the point where the walls of the abscess are thinnest; insert an exploring-needle, and if the dépôt of pus is reached substitute a trocar having a sufficient calibre to evacuate the contents of the abscess; observe antiseptic precautions in respect to each detail of the operative procedure, and after the removal of the canula or needle, if a drainage-tube is not necessary, close the wound antiseptically. If drainage is necessary, keep the cavity empty and use proper solutions to prevent septic decomposition. When an abscess of the liver is pointing, the best place to puncture is where the abscess is most prominent and it walls thinnest, but if the accumulation of pus is encysted and there is no attempt at effecting an exit, the exploring-needle should be passed into the interior of the right lobe, the most usual site of suppuration. If pus be reached, a larger trocar may be inserted to evacuate the cavity thoroughly. Repeated insertion of the needle-trocar is preferable when the abscess is small, but when the accumulation is large and sufficiently firm attachments to the abdominal parietes exist, a drainage-tube will be necessary.

In what direction soever discharge of an abscess may take place, the general indications are to support the powers of life by food and stimulants. The utmost quietude should be maintained. It is useful, by the application of a firm flannel bandage, to keep the liver in its proper position and maintain it there. When pointing of an abscess occurs, a large flaxseed poultice is a soothing and a mechanically supporting application.

Acute Yellow Atrophy.

DEFINITION.—By the term acute yellow atrophy is meant an acute affection of the liver, characterized by rapid wasting or degeneration of the organ, accompanied by the systemic symptoms belonging to an acute acholia or cholæmia. It is an acute, diffused inflammation, with atrophy of the proper gland-elements. It has been called icterus gravis, malignant icterus, hemorrhagic icterus, malignant jaundice, etc.

HISTORY.—Cases having a more or less exact resemblance to acute yellow atrophy have been occasionally reported from the earliest period. Amongst English physicians, Bright120 was one of the first to give an accurate account of the clinical history of some well-defined cases. Rokitansky121 was really the first to define the disease from the pathological standpoint, and it was he who designated it acute yellow atrophy, this term being intended to signify the nature of the objective changes. The first treatise ever published on the disease as a distinct morbid entity was the monograph of Horaezek,122 which appeared in 1843. Amongst the French, Ozonam in 1847 was the first to recognize and describe the disease as a distinct affection, although Andral123 had several years before mentioned an affection of the liver which corresponded in some of its features to this affection. In 1862, Wagner124 asserted that many of the cases of acute yellow atrophy were only examples of acute phosphorus-poisoning, and that no real distinction exists between the two affections. This statement has been warmly disputed by various German observers, but there is no doubt a close resemblance between the two affections.
