increased during the febrile period, and this is observable in a 

 more marked degree in women than in men. 



Andral 1 has communicated some observations regarding the 

 urinary sediments in pneumonia. Out of thirty-three cases, in 

 twelve the urine remained perfectly clear throughout the whole 

 course of the disease, and was not rendered turbid either by 

 nitric acid or by heat; of these cases in six even the colour 

 was not affected, and two sank under the disease. In nine 

 of the thirty-three cases the urine was alternately clear and 

 turbid or sedimentary. The sediments were for the most part 

 spontaneous, and composed of amorphous uric acid. In one 

 of these nine cases the urine contained albumen. The sedi- 

 ments occurred, as might be expected, in the different cases, 

 at different periods and under different modifications. In one 

 the urine was clear and of a reddish brown colour till the tenth 

 day, and then formed for the first and only time a grayish white 

 precipitate. In another case, the urine, which was of a brown- 

 red colour, did not become turbid till the ninth day, when, 

 as well as on the two following days, it formed a brick-red sedi- 

 ment. It then became clear, and remained so. In a third 

 case, the urine, which was deep-coloured, deposited a grayish-red 

 sediment on the seventh day, and then became clear and amber- 

 coloured. In the other twelve cases that remain from the 

 thirty -three, the urine was always turbid or sedimentary, either 

 spontaneously or on the addition of a few drops of nitric acid, 

 from the period of admission to the termination of the disease. 

 Three of these twelve cases terminated fatally, and in these the 

 urine remained turbid to the last. In the nine other cases the 

 urine returned to its transparent state at the cessation of the 

 disease. 



Becquerel has arrived at the following results respecting the 

 constitution of the urine in pneumonia. 



In a case of acute pneumonia at the period of the crisis, the 

 quantity of urine passed in twenty-four hours was 26 ounces, 

 its specific gravity 1015-1, and its amount of solid residue 24'9 

 in 1000. The patient was depressed, his pulse 96, and the 

 urine, as well as the skin, had a bilious tinge. 



In a second case, in which there was intense fever, and the 

 pulse was 120, 22 ounces of dark red urine of specific gravity
