Numerous extracts of the thyroid are upon the market, many of 
them purporting to be the active constituent. Aiodine. ojXfthyroidine^ 
and thyrogJandine are other preparations on the market. 
Thyreoidectin and rodagen represent a new series of preparations 
quite recently introduced which must not be confused with the above: 
their action is stated to be exactly the opposite of that of the thyroid 
preparations. Thyreoidtctin is prepared from the blood, rodagen 
from the milk, of animals from which the th^u’oids have been removed. 
GLTCERITUX FEREI, QUININT ET STETCHNINT PHOSPHATLAI. 
Glycerite of the Phosphates of Iron, Qiimine and Strychuiue. 
This preparation is a concentrated form of one of the popular and 
useful com binations of tonics which might well replace some of the 
many commercial articles; it is prepared according to a fixed and 
definite formula (see U. S. P.), whereas the latter class are made 
according to the special formula of the dift'erent manufacturers. 
(See also Elixir Ferri, Quinine et Strychninje Phosphatum.) This 
glycerite is a stable solution which may be kept in stock, and from 
which the Syrup of the Phosphates of Iron, Quinine and Strychnine 
ma}' readily be prepared. 
Dose. — ‘‘Average dose: 1 Cc. (15 minims)." (E. S. P.) 1 Cc. con- 
tains 0.080 Gm. =80 milligrammes (li grains) of soluble ferric phos- 
phate, O.IOL Gm.=10I milligrammes (1| grains) of quinine, and 
0.0008 Gm.=0.8 milligrammes (g^o gi’ain) of strychnine. The ratio 
of quinine to strychnine is four times as great in the glycerite as in 
the elixir.
