45. Canals in the Filaments of the Nerves. — Messrs Cu~ 
tier, Dumeril, Geoffroy St Hilaire, and Dupuytren, have been 
charged by the Academy of Sciences to examine the prepara- 
tions made by M. Bogros, in reference to his discovery of ca- 
nals in the filaments of which the nerves are composed, and to 
ascertain the existence of these canals, and of their true situa- 
tion in the nervous tissue. M. Bogros will, without doubt, be 
impressed with the propriety of varying his injections and prepa- 
rations in presence of the commissioners, so as to leave no doubt 
upon their mind. This point of anatomy is too important, and 
the commissioners are too well acquainted with anatomical re- 
searches, for their opinion regarding this discovery not to be de- 
finitive, and for their not determining with accuracy what may 
be perfectly ascertained, and what may still be doubtful in the 
matter. We shall make known the result of this investigation, 
so anxiously looked for by all anatomists. — Bulletin Univers.y

46. On the Iron in the Cruor , or red part of the Blood . — 
Englehart of Gottingen, from a series of experiments, concludes, 
that the red colour of the cruor of the blood is owing to iron, 
although this opinion has been controverted by Brande, Vauque- 
Jin and others. He found, when the cruor is deprived of its 
iron, that it becomes colourless. The iron is separated from the 
cruor by means of chlorine, a method much superior to those 
at present in use. -
