The specific gravity in these cases was 1007 and 1011.

 acid for some days, and the septic tendency had diminished.] 



Urine in intermittent fevers. 



The urine varies considerably in its physico-chemical relations 

 in this class of fevers. An abundant lateritious sediment at 

 the period of the crisis was formerly regarded as an acknowledged 

 characteristic ; recent investigations have, however, shown that 

 this is by no means an invariable occurrence. 



Schonlein observes on this point that he feels bound to con- 

 tradict the old physicians that the lateritious sediment in the 

 urine discharged at the termination of the paroxysm is a signum 

 pathognomonicum of intermittents, and that it may serve for the 

 purpose of distinguishing masked intermittents from similar 

 forms of disease, because the urinary crisis exhibits itself in 

 various forms, and in many epidemics is either altogether absent, 

 or only forms the exception and not the rule. For instance, 

 when the whole tendency of the disease is directed towards the 

 skin, the crisis is uniformly exhibited through that medium, 

 and an urinary crisis is either altogether absent or only occurs 

 subsequently, during the non-febrile state; so that while a 

 perfectly clear urine is discharged at the termination of the 

 paroxysm, the sediment which has been noticed occurs on the 

 following day. 



Becquerel examined the urine in fourteen cases of intermit- 

 tent fever, ten of which were of the tertian, two of the quartan, 

 and two of the quotidian type. During the intermission the 

 urine resembled the normal secretion, and the resemblance was
