disease, the inordinate temperature sometimes felt in 

 these conditions is to be ascribed solely to diminished 

 evaporation. 



4. Blood drawn during increased production almost always 



exhibits the buffy coat, whereas the same abstracted 

 in purely typhoid affections is seldom or never pre- 

 sent, although the system be apparently oppressed 

 by great heat. It follows also, where the production 

 is slightly greater than natural, that the buffy coat 

 will be proportionate to the influence of this cause. 



5. Whenever the skin is dry and hot, we may consider 



the functions of the capillary vessels to be much de- 

 range4- 



6. When the patient shows acute susceptibility to cold, 



how great soever the temperature may be, we may 

 justly suspect diminished evaporation. 



7. When the temperature is high, and the individual is 



not particularly sensible to cold, we may conclude 

 that the generation of caloric is augmented. 



8. The arteries, in continued fever, in different parts of the 



body, occasionally pulsate much more strongly than 

 natural, even when the truly inflammatory character 

 of the disease is past ; but such a symptom must not 

 lead the practitioner to suppose that this, in con- 

 junction with increased temperature from diminished 

 evaporation, indicates the necessity of depletion. 

 Such a phenomenon frequently occurs in dysentery 

 and other diseases characterised by internal conges- 

 tion. It does not arise from conditions that attend 

 the ordinary excited states of the arteries, viz. the 

 more stimulating properties of the blood and its 

 greater propulsion, but from obstacles to its free cir- 

 culation.
