11.) Compound Tincture of Lavender. Fowler’s original for¬ 
mula contains “a half ounce” 98 of Compound Spirit of Lavender. 
Of this addition he says 99 “The small Proportion of Compound 
Spirits of Lavender is added, merely for the sake of giving a 
medicinal appearance, least, from its being colorless and tasteless, 
those patients who may happen to be intrusted to drop it for them¬ 
selves, should be tempted to use it with too great freedom; the 
consequences of which might frequently prove troublesome, if not 
sometimes dangerous.” In this connection two things are note¬ 
worthy: firstly, that the Compound Spirit of Lavender contained 
the alcoholic extractive of cinnamon, nutmeg and red saunders 100 
in addition to the aroma of the lavender, and secondly, that the 
patented preparation of Wilson, 101 after which Fowler’s prepara¬ 
tion was modeled,, contained red saunders as coloring matter though 
it contained no aromatic. 
The London Pharmacopoeia of 1809, which apparently was the 
first to adopt Fowler’s solution, likewise prescribed the use of 
Compound Spirit of Lavender. The authors of the U. S. P. of 
1820, however, apparently regarded this addition or disguise as 
unnecessary or even undesirable. Thus Bigelow 102 states that
