v. ad Aq. fj.) is spoken of by Dr. Druitt, as an efficacious application.

2717. In Diseases Of The Eye, M

Hairion§; speaks highly of the efficacy of a strong solution of Tannin (one part of Tannin and three of Water) as a local application. Amongst other forms of disease in which it proved successful, are Acute and Chronic Conjunctivitis, vegetating Granulations, Corneitis with or without Ulceration, Chemosis, and Pannus. It is in this last form that it proved the most successful. He adds that a solution of the above strength produced no ill effects whatever; but general experience is against so powerful an application; one part of Tannin to twenty, thirty, or fifty parts of water, is a sufficient strength for ordinary cases. Thus diluted, it is a valuable astringent colly-rium, and is much employed in modern practice. M. Hairion also employs it in the form of pomade, and in fine powder. In solution, it is regarded as preferable to all other applications by Dr. Cummins,* in the Purulent Ophthalmia of infants.

2718. In some obstinate Skin Diseases, and to Ulcers with copious discharge, the application of Tannin, either in solution (gr. iv. - v., Water fj.), or in ointment (gr. iv. - v., Lard j.), has been found of great service. In Porrigo Decalvans, it is particularly recommended by M. Cazenave; the parts being also washed daily with an alkaline solution. In a case of Vascular Tumour of the Orbit, Mr. Haynes Walton effected a cure by local injections of a saturated solution of Tannin; and Dr. Quinlan successfully treated by the same means (Tannin 3j., Aq. fj.) a case of Nvus in a child of nine months old. In Osmidrosis, Mr. E. Wilson§ states that in one case, where general means had failed to correct the fa-tor of the perspiration, Tannin effected a complete cure.

2719. In Intermittent Fevers, M

Leriche|| speaks highly of the value of Tannin in doses of j - 3ss., according to the intensity of the disease, taken three hours before the paroxysm. Two or three doses are usually sufficient to effect a cure, and it may be necessary to exhibit 3j., or even 3j.1/4, at once.
