The alloy of Chattier, and tine project of Lafolle, shared 
‘the same fate, as is seen by the report of the commission- 
ers, and by the labours of the abbe Monges and of Bayern 
The alloy of M. Buschaendorf, of Leipsic, presented 
in 1802, and described in the Annates des Arts et Mann - 
* factures , forms the subject of the last paragraph, Proust 
subjected it to the same experiments as the preceding : 
he proves that it is attended with the same inconveniences, 
without having any of the qualities announced by Bus- 
chaendorf 
Part II. 
On the Old Method of Tinning . 
This part consists of ten paragraphs!, M. Malouin* 
while he proposes his mixture, does not condemn the old, 
but he mentions the dangers to which people are exposed 
by this kind of tinning. Remerlin, Hellot, Geoffroy, 
Doucet, Chartier, Lafolie, Buschaendorf, and others, have 
done no more : but no one has hitherto proved the reality 
of these supposed dangers ; and what is still more asto- 
nishing is, to see the inactivity of the chemists of Europe 
in realising or exploding a fact which is so interesting to 
society. To decide the question in a peremptory man- 
ner, it was necessary to undertake a series of experiments 
which had before been neglected. To succeed in them 
it was previously necessary to examine the properties of 
some metals and oxyds ; and there are nine paragraphs 
employed in the examination of iron, antimony, mercury, 
lead, and zinc. This examination was requisite to an- 
swer all the objections which he proposed to resolve in 
the third part of this work. 
Part III. 
This part is divided into five paragraphs. 
Paragraph I. 
Experiments made on the Old Method of Tinning. 
Five plates of copper each a foot square, were tinned, 
all the necessary precaution being taken. The object of
