EXPOSITION OF 1867.

tagious diseases wliicli have proved so destructive in portions 
of Europe during the past few 3 ^ears; but horses, sheep, goats, 
camels, swine, and other species, had place on the island of 
Billancourt, and together made an interesting exhibition. 
Several fine blooded horses from St. Petersburg, sent by the 
Emperor, and during the Exhibition kept right royally in the 
Eussian quarter of the Park, attracted great attention and re¬ 
ceived appropriate awards. Several camels from Egypt added 
grotesqueness to the already singular looking Quartier 
d'Egypte, 
Of the implements of agriculture—also chiefly shown on 
Billancourt—space would fail to make adequate notice. But few 
new ones were there, however, and none of those of striking im¬ 
portance. McCormick’s Eeaper and Wood’s Mower sustained 
the American supremacy in their department, and each re¬ 
ceived a gold medal, while their worthy inventors were deco¬ 
rated by grace of His Majesty the Emperor, with the Gold 
Cross of the Legion of Honor. Comstock’s Eotary Spader 
was also there, and made two or three quite successful trials in 
the field, winning a Silver Medal. 
PEOGRESS OF THE CHEMICAL ARTS. 
The Chemical Art seems to have been no less active during 
the past than during the previous five years. To the great 
number of beautiful dyes derived from coal—mauve, magenta 
and others—that delighted the curious at the Exhibition of 1862, • 
and added new value to so many beautiful tissues, there have 
been added others scarcely less wonderful and precious. Not 
only so, means have been invented for using some of them as 
pigments, as which they are said to be no less beautiful and 
unfading than as dyes. 
Improved processes for the extraction of metals from their 
ores, as well as of a number of new and valuable sub¬ 
stances from petroleum and a multitude of salts, dyes and 
pigments from mineral and vegetable sources afford other 
equally remarkable illustrations of the truth of the general 
remark above made.
