ILLUSTRATIONS OF URINE,Plate IV. Oxalate of Urea, C2H4N202, HO, C303. Fig. i. Crystals of oxalate of urea, obtained by re-crystallizingnearly pure oxalate of urea from an aqueous solution, a. Dendriticmasses, in which the form of the crystal is not very distinct, b. Massesof well formed crystals, c. Perfect crystals of oxalate of urea. Fig. 2. Crystals of oxalate of urea obtained by evaporating healthyurine to dryness, and extracting the residue with alcohol; the alcoholicsolution was then evaporated to dryness, and water added until theresidue had a syrupy consistence; to this oxalic acid crystals were addedin sufficient quantity to form an oxalate with the urea present, d. Re-presents the general character of the crystals of oxalate usually formedin this manner, e. More perfect crystals. urine-iv:

The researches of Perls, p. 36, prove what was rendered almostcertain by another order of facts, that at least much of the urea isformed in the kidneys; and it is most likely that in many cases ofdisease, in which a large quantity of urea exists in the blood, much ofthis has been re-absorbed from the renal structure, instead of beingcarried away from the organ by the ureter. Urea cannot be detected in the muscles, but can be readily pro-duced from several substances found in them. Removed from thebody, very slight causes are capable of effecting its decomposition, andresolving it into ammonia and carbonic acid—substances of the highestimportance to the growth of plants. It has been generally concluded that any albuminous matters takenin the food, in excess of what is required for the nutrition of the system,is at once converted i
