250 THE SECRETIONS: 



urine threw down a sediment spontaneously on the third day 

 of the fever, and after the addition of an acid on the eleventh, 

 twelfth, and thirteenth days, death occurred on the fifteenth 

 day; in other cases, in which sediments appeared at intervals, 

 convalescence took place. Out of twenty-seven observations, a 

 sediment first occurred in one case on the third day of the dis- 

 ease (death) ; in one case on the fifth day (death) ; in one on the 

 sixth (recovery) ; in three on the seventh (two deaths, one re- 

 covery) ; in one on the eighth (recovery) ; in four on the ninth 

 (recovery) ; in five on the tenth (recovery) in four on the 

 eleventh (recovery) ; in three on the twelfth (recovery) : in four 

 cases the sediment first appeared after the twelfth day (recovery) . 



Amongst Becquerel's thirty-eight cases, he only found blood 

 in the urine in two cases : in one the patient was dangerously 

 ill, and a small quantity of blood was found in the urine every 

 morning ; in the other, the patient was recovering from fever 

 when he was attacked with small-pox. Albumen was found in 

 eight cases, in which neither pus nor blood was present. Of 

 these eight cases, four had the fever very severely, three mode- 

 rately, and one slightly. Of the severe cases, two terminated 

 in death ; in one of these albumen was only found during the 

 last eight days ; in the other it occurred first on the twenty- 

 fourth or twenty-fifth day, and subsequently from the thirty- 

 first to the thirty-eighth day, when death took place. In the 

 other cases the albumen only appeared at intervals. 



Andral examined the urine in forty-one cases of abdominal 

 typhus, of which seven died. They were all treated by copi- 

 ous bloodletting. In eleven out of the thirty-four who re- 

 covered the urine did not differ in appearance from the normal 

 type, and nitric acid threw down no precipitate. In the other 

 twenty-three cases, the urine was generally deeply coloured, 

 (of a reddish tinge,) and became turbid either spontaneously 

 or after the addition of nitric acid. In some cases it remained 

 turbid throughout the whole course of the disease ; in others 

 it presented no turbidity at first, even after the addition of 

 nitric acid ; but as the febrile symptoms attained their greatest 

 height, it became clouded, and as they disappeared, it gradually 

 regained its original appearance. In other cases the appearances 

 of the urine possessed no regularity, and it was clear and turbid 

 or sedimentary by turns.
