INTRODUCTION. XII It can searecly be stated that the bones participate in all the disorders of the system, which directly give rise to depravation of the fluids cireulating through the soft tissues, and, In eonsequenee, to changes in their com- ponent elements, Whatever peculiar immunities from disease the bones evince, are, it may be presumed, owing to the character of their organization, in respect to the earthy eonstituents so largely entering into their eompo- sition. There are, however, instances in whieh the bones, participating in the general disorders of the system, do undergo changes in their elements, and throw forth morbid produets of the same character as those oeeurring at the time in the softer tissues of the body. Thus in gout, the carthy phosphates in the bones have been diminished, peculiar produets have been found in them, and peeuliar conerctions have been thrown forth from them, but they were sueh as are characteristic of the gouty constitution’.
