The most elaborate and carefully prepared paper on this subject is from the pen of Dr. Lattemore, in a late number of the American Journal of Medical Sciences. In this essay Dr. L. details the method pursued by M. Pi- orry—his extreme tact in detecting enlargement of the spleen—his success in reducing this organ by the use of chloride of soda.— Most of the cases of intermittent fever met with in the. Parisian Hospitals are of lone; standing and importedfrom Algiers, says Dr. ' L., and they are always accompanied with enlarged spleens and difficult to cure. “ We witnessed,” says this writer, “ many of the ex- periment!jl()f M. Piorry, and in a great majority of cases the fever yielded to salt quite as readily as to the salts ofquinia.” M. Piorry's method of administering the chloride qf soda is, to give half an ounce in a cup of thin soup during the apyrexia (intermission) and fasting. It generally agrees with the stomach; rarely purges or vomits. Three doses usually suffice to effect a cure.
