THE URINE.

We shall conclude our treatise by a few remarks on diseases of the urine, to which many are subject. Before proceeding to speak of them, it is necessary, for a full understanding of the subject, to state, that the urine is secreted by two bodies called kidneys, placed one on each side of the back-bone, as is shown in the cut. After being formed, the urine passes through the ureters into the bladder whence it is voided, as every one knows, occasionally.
