several works, all of which have perished. Cælius Aurelianus attributes to him a treatise, in several books, on Dietetics; and another, also in several books, entitled "Comparatio."

Philomenus, another writer of the Methodic sect, flourished about this same epoch, and is occasionally quoted by Oribasius, Aetius, and Alexander Trallianus. He pointed out the affinity between dysentery and the prevailing fever of the season. He was the first to recommend assafoetida and frictions with tepid oil, for the treatment of tetanus. He wrote on the diseases of women, and on the removal of the foetus by artificial means.*

Archigenes of Apamea, in Syria, was in great repute at Rome, as a physician and surgeon. He flourished in the reign of Trajan. His works were numerous, and are often quoted with commendation, by Galen and others. He wrote ten books on fevers, three on local affections, also on the use of castor, and of hellebore in mentagra and other, cutaneous affections; and on surgical diseases, some fragments of which are still extant in the collections, of Nicetas. His description of the operation of amputating, is worthy of notice. He begins by retracting the integuments of the limb; he next applies a circular compress or tourniquet for controlling the loss of blood; he even recommends, when necessary, a preliminary operation for securing the bloodvessels and stitching them, before proceeding to the

amputation. This he performs invariably at the joint, by a circular incision. After the removal of the limb, whatever hæmorrhage occurs he arrests by the actual cautery; taking due care not to apply the heated iron to the divided extremities of

nerves.

Heliodorus is also more particularly noted as a surgeon. Fragments of his writings on wounds of the head, on fractures of the skull, and other injuries, may also be found in Oribasius* and the collections of Nicetas. His remarks on injuries of the skull are judicious, and indicative of a careful observer; and his treatment, such as might be recommended at the present day. His dressings are light, his local applications simple, usually moist compresses, roseated oil, simple cerate, and tepid water. For controlling inflammation he resorts to low diet, and occasionally to venesection. He speaks of amputating in the continuity of the long bones, but looks upon operations above the knee and elbow as extremely dangerous, from loss of blood. To obviate this danger as far as possible at other points, he makes his incision first through those parts of the limb in which the bones are most superficial; he next saws through the bones; and he reserves his incision through the fleshy part of the limb, where the vessels are most numerous, to the last.

by Galen, is by some writers presumed to have preceded him, whilst by others he is placed as late as the reign of Valerian. He is frequently mentioned by. the later Greeks. In the collections of Nicetas* is a

fragment of his on elastic or watery tumors of the head, superficial and deep-seated; including among the last, congenital or chronic hydrocephalus. The superficial varieties he encounters with fair hope of success, but with those more deeply seated he is indisposed to interfere. He treated humid asthma with suffumigations, placing the patient in such a position as readily to inhale the fumes from particles of aristolochia or clematis previously sprinkled over burning coals in a chaffing-dish or brasier. He operated on cataract by extraction; with Asclepiades, he recommends tracheotomy in threatened suffocation; and he treated hydrocele by incision.

Soranus of Ephesus, the second of that name, was educated in part at least at Alexandria, and praeticed with great eclat at Rome under the reigns of Trajan and Adrian. Ile was celebrated both as a teacher and practitioner; and is admitted to have been the ablest exponent of the Methodic doctrines, which he carried to their highest degree of popu larity. He was the first to mention the Dracunculus or Guinea worm (vena medinensis.) Among the fragments of his writings still preserved, we have a treatise on the female organs of generation, and another on fractures, which is contained in the col-.

lections of Nicetas, and is mostly made up of definitions. This second Soranus is not to be confounded with still another of the same name, also of Ephesus, a writer of later date, and the reputed author of a memoir on the life of Hippocrates. The works of the second Soranus, though mostly lost, served as the model for those of Cælius Aurelianus, who is supposed to have embodied the greater part of them in a translation. To him, therefore, we must next direct our attention.*

Cælius Aurelianus, sometimes called Lucius Cælius Arianus, was a native of Sicca in Numidia. He appears to have been a voluminous writer. Besides his work on Acute and Chronic Diseases, which is preserved entire,t he was the author of Greek Epistles addressed to Prætextatus; of a work on Fevers, and of another on Diseases of Females; of distinct treatises on the Causes of Disease, on Surgery, on the Rules of Health, on Adjuvants or the General Remedies of the Methodic sect, and on Medicaments; besides several books of Medical Interrogations and Responses; and a book of Problems;—all of which have perished. His work on Acute and Chronic Diseases is written in impure Latin; and much of it, as the author admits, has. been borrowed from Soranus. But it can hardly be considered a translation, since much of it was evidently the result of the author's own observation and experience.

tuting this work, three are devoted to the history and treatment of acute, and five to the history and treatment of chronic diseases. The several maladies. are arranged in the usual order from head to foot, considered in their relation to concomitant constitutional disturbances, and spoken of as accompanied or not accompanied with fever. This valuable summary of theory and practice, can scarcely be considered as advocating only the doctrines of the Methodic sect. Though its author is a favorer of these doctrines, he speaks as an independent observer, criticises the leading writers of his own party, and, in disposing of his materials, gives first his own proper opinions on the history or pathology of the disease in question, and afterwards those of the several leading writers of the other sects; drawing, however, almost exclusively from the Greeks, and furnishing a systematic exposition of the theory and practice of physic, both of his own and previous times. But in referring to his predecessors he is much more solicitous to give their treatment than their pathological opinions; which, however, he does not entirely overlook. Cælius Aurelianus, quoting from Soranus, is the first writer in whom I remember to have met with a practical distinction between what he calls the signs and the symptoms of disease, a distinction still worthy of remembrance: the signs being always present during the existence of the disease; the symptoms being mere accidents, that may or may not be observable, without necessarily implying any essential modification in the disease itself. His chapters on diseases of the head are ably written, and evince much prac
