It is not a little remarkable, that after the able and valued testimony just alluded to, an agent of such therapeutical properties should have been allowed to fall into utter neglect in this country. Much praise is due to the physicians of Germany for investigating the subject, and practically testing its efficiency. It would be out of place here, and foreign to my purpose, to call attention to the various trials to which the remedy has been submitted and its efficient powers confirmed; these are to be found in the medical periodical literature of Germany and France, and have been translated and transferred to the pages of our own journals. (See “Medical Gazette,” “Lancet,” “Pharmaceutical Journal,” “Medico-Chirurgical Review,” “British and Foreign Medical Review,” “Continental and British Medical Review,” “London Journal of Medicine,” &c.) The cod-liver oil has been found principally efficacious in rheumatic, gouty, and scrophulous cases, with their accompanying manifestations of cutaneous eruptions and neuralgic pains. Whenever a deficiency of tone is apparent in the system, its employment has been found of benefit. Where, as in pulmonary cases, it cannot be looked upon as curative, it nevertheless tends to the general support of the frame, and may probably serve to give time for the employment of other remedies more especially directed to the existing disease. That cod-liver oil should produce fatness, will not occur as remarkable to any one who looks at its composition, the principal ingredient of which consists of carbon; this is present in all oils to a great degree, and it therefore offers a very valuable aid in cachectic cases, and others of diminished power and general weakness; hence it has been remarkably efficacious in cases of mesenteric disease: its powers also in exciting the lymphatic system to activity, in promoting also the capillary circulation, and in effecting absorption of scrophulous deposits, have been very striking, and demand the attention of every practitioner. Its effect is not merely increasing the deposition of fatty matter in the system, but, as Dr. J. C. B. Williams has asserted, increasing the muscular strength and action, and improving the colour of the cheeks and lips, and thereby affording evidence of improving the nature and condition of the blood. Dr. Copland, in his valuable Dictionary of Medicine, has given his approbation to its employment in cases of rheumatism and sciatica, and also in several cases of neuralgia. It would form a volume to give, even in abstract, the cases which, within the last three years, have been recorded of the efficacy of the cod-liver oil in a variety of affections; and my object in at all addressing the public on this occasion, is to point out the necessity of obtaining this remedy in its purest and most effective form, in order to insure its operation, and prevent it from falling into that desuetude which has characterized so
