is totally dissolved when the smoke has entirely abated in 
the matrass ; pour into it, by little and little, prepared nut 
oil, stirring it in order to incorporate the whole completely. 
Afterwards, and in the same manner, the spirit of turpen- 
tine is poured in, and the mixture is then taken from the 
fire, filtered, and cooled; it is then made use of to grind with 
ile Prussian blue and indigo in small quantities at a time, 
and the whole is well mixed together. 
This mixture forms the fine varnish for the purposes in- 
dicated. 
Il. Memoir upon Waters distilled from Plants described as 
being inodorous, upon the Distillation of Water intended 
for Chemical Experiments, and upon Alembics. With 
a Note sulbjoined by M. DeyvEux on the Subject. By 
M, DescROZIILLES sen.* : 
Aone those whose professions lead them to the prepara 
tion and application of medicines, there are various opinions 
upon the efficacy of waters distilled from plants described: as 
inodorous. I shall by no means decide upon the question 
ina medical point of view ; I shall only request that before 
entering on the discussion the question be stated in ‘precise 
terms, 
I was induced last summer to repeat some experiments on 
the distillation of inodorous plants, im consequence of read- 
ing some observations on the subject in a former number of 
the Annales de Chimie t. 
The observations of the learned author in the above me- 
moir lead me to offer some hint which may tend to give 
a new direction to his useful researches. 4 
Waters distilled from a great quantity of inodorous plants 
yield a smell so much the stronger, the oftener that the pro- 
duce of the first distillation has been cohobated upon fresh 
quantities of the same plant; but I do not think it has been 
yet demonstrated that such waters are susceptible of putre-
