ditions, in the adult than in the recently born; and that the 
differences in the resistance to asphyxia existing in animals 
of different species and ages, must not be considered as 
differences depending upon the temperature of the animal 
itself, that is to say, upon the difference in the properties of 
the tissues and organs in the different species and at various 
ages. 
SUGAR IN THE BLOOD. 
M. Sanson, of Toulouse, still maintains his assertion, that 
dextrine exists normally in the blood and tissues of the her- 
bivora. The reason why experimenters in Paris could not 
obtain it is that they operated upon butchers* meat—that 
is to say, upon tissues taken from animals killed by loss of 
blood. M. Sanson’s experiments were all made on animals 
that died from disease, and where the blood still remained in 
the body. 
THYMUS GLAND. 
M. Friedelben shows in his work on the thymus gland— 
1st. That this organ may be removed without injury to the 
general health of the animal. 2d. '1'hat animals deprived of 
their thymus gland take a larger quantity of food than natural. 
Sd. That the increase of the body of animals operated on is 
absolutely greater than that of animals in a normal state, but 
that relatively to the quantity of food taken the growth is 
less. 4th. The sanguification of blood in them is more rapid ; 
the blood is richer in albumen and water; the number of 
globules of the blood is absolutely greater, but that of the red 
globules absolutely less; the excretion of albuminous matters 
is increased, of carbonic acid lessened; the excretion of water 
by the skin greater, by the kidneys less. 5th. The growth 
and chemical constitution of the bones are also affected by 
the extirpation of the thymus. The pathological deductions 
from his physiological researches are—1st. That the thymus, 
neither in its normal nor in its hypertrophied state, undergoes 
turgescence, excepting after the taking of food; and that the 
pretended hyperaemic and periodical turgescence does not 
really exist. 2d. That the organ never interferes with the 
respiration or the circulation, either in its normal or in its 
hypertrophied state, nor compresses the respiratory nerves ; 
and 3d. That in neither state, therefore, does it interfere with 
the cerebral circulation, or the innervation of the nerves of 
the glottis .—Medical Times and Gazette .
