ANALYSIS OF CONTINENTAL JOURNALS.

In typhus and typhoamia the increase is slow and rapid. 
He saw a horse in which the temperature rose in a few days 
to 39°, 40°, and 40^° shortly before death, in others in fifteen 
hours from 39° to 42j°; in cattle, in twenty-four hours to 
41 f°. 
In cerebral typhus of the ataxic form, the thermometer is 
a most valuable guide, as it shows a marked elevation of tem¬ 
perature when there is scarcely any acceleration of the pulse. 
The thermometer enables the practitioner to distinguish 
abdominal typhus from serious gastro-enteritic catarrh at the 
very commencement. In the first a series of ascending 
oscillations generally leads to the maximum. In the second 
the thermic cycle of elevation is less considerable. 
Peters has more particularly studied thermometry in 
pneumonia and pleurisy. In the first the temperature often 
attains at the commencement 41 , 3°, and is maintained at the 
elevation with but slight variations morning and evening. 
Towards the fifth, sixth, or seventh day it decreases, until in 
twenty-four hours it has reached its normal degree, &c. In 
this malady there is a relation between the augmentation 
and diminution of the temperature, and the acceleration and 
lessening of the pulse. 
In pleurisy the modifications of the temperature are not 
so regular; at the commencement elevation, and often after 
two or three days diminution, without the other symptoms 
decreasing in intensity. 
In acute tetanus the pathological temperature attains its 
maximum ; not only does it increase during life, but it even 
rises after death. The gravity of the prognosis depends on 
the degree to which the temperature has attained. 
Clinical thermometry has also been studied in external 
affections, as in traumatism, by Billroth and 0. Weber; 
and Jacmann has applied it in chronic diseases; such as 
tuberculosis in man. 
Brusasco briefly alludes to the importance of thermo¬ 
metry with respect to prognosis and therapeutics. The 
prognosis of a disease is serious in a direct ratio with organic 
combustion (febrile consumption), which is related to the 
thermical degree. A sudden and marked elevation is a bad 
augury as to the termination of a case. According to the 
Professor, every fraction of a degree above 41° C. in the 
horse increases the danger. He does not agree with Schweiz, 
who says that any diminution of temperature in febrile 
maladies is always a favorable prognostic sign, even when 
there appears to be no amendment in the other symp¬ 
toms, &c.
