The new plan of procedure suggested by Mr. Tyrrel consists The local treatment is equally important. Cupping to the temple must be employed, and should be repeated, if necessary, in scarification of the conjunctiva in radii diverging from around within moderate limits; for arterial blood constituting the prin- the cornea. The object is to relieve the tension of the con. cipal supply of the cupping-glass, an extravagant expenditure by junctiva, and the pressure exerted by it upon subjacent structures; this method is likely to be of still greater eventual injury than to allow the effusion confined in the meshes of the reticular tissue the abstraction of a similar quantity from the arm. You may to escape; and to permit what remains to expand without injury may perhaps be surprised at my laying so much stress upon the to the vascular net-work around. I have myself frequently tried this operation, and am convinced point of not carrying depletion to too great an extent. The quotations just made, however, from authors of consideration may of its propriety in cases of purulent ophthalmia, with chemosis, show how theoretically the opposite plan has been enjoined; and threatening the integrity of the cornea. The idea upon which it I have myself witnessed years ago that plan pursued so far in is founded possesses great claims to attention; for besides the practice, and with such results,as to make me exceedingly solicitous high authority of its promulgators, many circumstances in the to guard against its future prevalence. From eight to twelve history of the disease lend it support; but whether the theory be ounces of blood, therefore, I should state as the full limit of a admitted to the full or no, certainly this method of scarification single cupping; and this quantity should not be withdrawn more holds out advantages rendering it well deserving of general adop. than twice, or at most three times, and only upon urgent occa- tion.

we may well believe to possess The fomenting liquid should be between the lids by six grains of alum to the ounce of fluid. A mild ointment may be advantageonsly applied between the palpebroe to prevent cohesion, especially at night. Added to these remedies, and one of the most important of all, is the strong nitrate of silver solution made in the proportion of from six to eight grains to the ounce of water. It should be instilled between the lids four or five times in the day. For an important accessory in the treatment, directed especially to the immediate object of saving the cornea, we are indebted to the late Mr. Tyrrel. Mr. Travers, in his Synopsis of the Diseases of the Eye, had pointed out incidentally, many years ago, what he considered the true pathological cause of the destruction of that membrane. Adopting the theory thus thrown out by his predecessor, Mr. Tyrrel argued that if’ sloughing of the glans penis in paraphymosis results from obstruction to the circulation of the part, and is obviated by relieving the constriction-if sloughing of the cellular membrane in phlegmonous erysipelas of an extremity results in great measure from the unyielding tension of the affected integuments, and is averted by timely longitudinal incisions-then, to attain a similar end, analogous means must be put in operation in purulent ophthalmia, if a corresponding condition is found to arise in its progress. That the state of inflammatory chemosis constituted such condition was the belief of the accomplished surgeons just mentioned, who came to the conclusion that the destruction of the cornea in this disease is the result of mechanical impediment to its sanguineous supply, and is not due merely to inflammatory action in its immediate vicinity. They believed that in consequence of the extreme distention of the sub-conjunctival tissue the bloodvessels passing through and beneath the conjunctiva towards the cornea are in part so forcibly compressed against the scleroticin part so acutely bent upon themselves at the anterior margin of that structure, where the chemosis abruptly terminates-that the flow of blood through them cannot continue with the requisite freedom. The cornea therefore perishes, they concluded, like a gl1ns penis constricted by unrelieved paraphymosis -like a hsemorrhoid ligature by the surgeon-or an extremity, the main artery of which has been torn through. This very ingenious rationale of the circumstances attending

inferior rectus. The conjunctiva thus divided no longer confines the effusion in the cellular structure beneath, and the vessels proceeding to supply the cornea are relieved from compression. The reason of selecting the intervals between the recti is, that vessels of considerable moment to the conjunctiva and cornea pierce the tendons of those muscles, and would be endangered by incisions made in any other situation. It often happens that the tumefaction of the palpebrse is so great as seriously to obstruct exposure of the globe, and impede the performance of the operation just described. It is then necessary to begin by dividing the external commissure of the eyelids. This step has the double advantage of facilitating proper scarification, and at the same time of preventing that counter-pressure which the superior palpebra must ever exert upon the globe when (as in the disease now under consideration) parts enclosed by the eyelids are materially augmented in bulk. There is good ground, too, for believing that the pressure of the tumefied upper lid upon the cornea has no inconsiderable share in producing the destruction of that tunic; for it is obvious that this pressure must greatly contribute towards the strangulation of the vessels, while it is often the central and consequently most prominent portion of the cornea which suffers most. I unhesitatingly, therefore, advocate the use of these combined measures, feeling assured that, in adopting them in conjunction with the other remedies already specified, you will succeed in saving the cornea (upon which recollect the preservation of sight entirely depends) in a far larger proportion of instances, and with less call upon the constitutional power, than by resorting to the fearfully debilitating treatment formerly in vogue. After the acute stage of the disease has subsided, the purulent discharge has ceased, and both inflammation and chemosis are diminishing, you may employ a weaker solution of nitrate of silver, or substitute a solution of alum, of sulphate of copper, or of zinc, for the strong collyrium at first necessary. I have known very marked good effect result from a collyrium composed of eight minims of the solution of diacetate of lead, two drachms of Battley’s solution, and six drachms of rose water, even before the complaint could be considered to have fallen into the absolutely chronic state. As the violence of the disease more and more declines, especially if the subject be weakly, he will derive benefit from tonic medicine and tonic diet. The strong solution purutent ophthalmia has led to a great improvement in treating nitrate of silver may again be used, and even the caustic be the disease ; yet I cannot acquiesce in the universal or momentarily applied in substance, if an indolent ulcer be creep. general truth of the above theoretic views on this subject, as in ing on slowly, to open the anterior chamber ; or, having done so, a
