4, That it bas the peculiar advantage of allowing the workman to 
weave on the next day, without breaking a great many threads, the

25. French Ultramarine.—The price of the Artificial Ultramarine, 
the process for manufacturing which has been discovered by JM. 
Guimet of Paris, (V. Am. Jour. XV. 392,) has been so reduced as 
to make it an object with painters and colormen, in point of econo- 
my, to substitute this article in the room of cobalt in the bluing of 
paper, thread, and stuff in which this material is employed. The 
discoverer has purchased a situation three leagues from Lyons, in 
which he is about to establish a manufactory on a scale, sufficiently 
large to satisfy the demands of commerce. 
M. Guimet has proved by trial, that a pound of his ultramarine. of 
the second quality, and which can be afforded at twenty francs, will 
blue as much paper as ten pounds of cobalt, which at wholesale, costs 
twenty six francs, and an important advantage of the former is that 
on account of its lightness, it spreads more uniformly over the paper. 
Since his success in this application of the new color he has tried it 
in dyeing, and has obtained upon linen, cotton and silk, a degree of 
success which encourages the hope of angiltimate and decided supe- 
riority over indigo. 
In his printed circular, M. Guimet offers his ultramarine for blu- 
ing paper at sixteen francs. Report of M. Merimée to the Societé 
a@’Encouragement.—Bull d’ Encour. Avril, 1831. 
26. Singular Case of Odoriferous Emanations.—In the 34th Vol- 
ume of the Memoirs of the Royal Academy of Sciences of Turin; 
(1830) Dr. Speranza of Parma relates the case of an individual whose 
jeft fore arm emitted an odor of Amber, or of Benzoin, or Balsam of 
Peru. The odoriferous emanations were sometimes so strong that 
they filled the whole of the large room in which the Doctor conduct- 
ed his experiments upon this personage, whom he suspected at first 
of some charlatanry, but of whose sincerity he was soon convinced. 
He was a man of thirty four years of age, of a robust constitution, 
(having, until that time enjoyed constant health) agreeable eyes, €%- 
pressive features, dark thick hair, a ruddy countenance, muscles 
romine man of ardent feelings and quick penetration; t0
