Ipecacuanha deprived of its nauseous substance. — M. Gay has given the 
following method of depriving ipecacuanha of its nauseous odor and dis- 
agreeable taste, which are often so inconvenient as to prevent its pre- 
scription by practitioners. 
Take of pure rectified sulphuric ether, 6 parts, 
Finely powdered ipecacuanha, 1 part. 
Mix the powder in the ether, allow it to macerate for several hours, and 
filter ; wash the powder with a small quantity of pure ether, dry it, and 
when the powder has lost the ethereal smell, triturate, and preserve 
for use. 
The dose of the powder, thus prepared, is the same as that of common 
ipecacuanha ; in fact it has not lost any of its active principle.

Syrup of Cod Liver. — In Switzerland and Germany, the oil of cod liver 
is recommended in gouty and rheumatic affections, obstinate constipation, 
incontinence of urine, scrofula, rachitis, &c. M. Caron Villard has 
directed the attention of practitioners to this oil, and M. Duclon, pharma- 
cien, in order to render it of more ready administration, has converted it 
into a syrup, the formula of which he gives in the Bulletin General de 
Therapeutique. The following is the formula: 
Take of Oil of Cod Liver, 3 viij. 
Gum Arabic, powdered, ^v. 
Water, gxij. 
Syrup, giv. 
Sugar, ^xxiv. 
Make of the syrup, gum, oil, and water, an emulsion, in which dissolve 
the sugar with gentle heat ; filter, and flavor with two ounces of orange 
flower water. 
The dose administered depends upon that of the oil. It is three or 
four table-spoonsful a day for adults, and the same number of tea-spoons-
