    I. Yellow Sediments. These owe their colour almost entirely to the na- tural colouring principle existing in healthy urine. No. 1 and 2 are the tints sometimes exhibited by crys- tallized gravel, when tinged simply by the principle in question. The paler tints of this class, as No. 3, are sometimes met with during the transition stage exist- ing between the lithic acid and phosphatic diatheses. This class of sediments is confined to peculiar states of the general health, and does not necessarily indicate fever. II. Red or Later itious Sediments. No. 1 is the most perfect tint of this class, and is not common, being confined for the most part to crys- tallized gravel deposited during fever or inflammation. No. 2 is the tint, some shade of which is usually as- sumed by amorphous sediments deposited during fever. No. 3, or some tint between this and No. 3 of yellow sediments, is perhaps the most frequent of all the forms assumed by amorphous sediments, and is that which occurs during slight feverish irritability produced by errors in diet, &c. This class of sediments almost always indicates more or less of fever, and owes their colour to a mixture of the tints of the first and third classes. III. Pink Sediments. This class of sediments owes their colour to the pur- purate of ammonia chiefly, and is rather of uncommon occurrence. No. 1 is taken from a very perfect specimen sent me by Mr. Astley Cooper. It occurred after the operation of paracentesis, for dropsy. Nos. 2 and 3 are also from dropsical urine. Mr. Cruickshank sup- posed this form of sediment to indicate disorganization of the liver. I am disposed to agree with him so far, as to believe that it frequently indicates some great derangement, if not disorganization, of that viscus.
