The influence of a depressing poison on a tender developing bone is none the less on account of this difference in causation, although manifest often in a different manner. Diathetic Causes. Our knowledge of scrofula and tubercle in their causal relations to Pott's dis- ease is as yet not of that definite character which is desirable, and therefore cannot receive more than a passing notice. When we speak of scrofula refer- ence is had rather to a state or vulnerable condition of the tissues than to a complete pathological entity. Scrofula, therefore, we would refer to as a condition of the system rendering it peculiarly prone to chronic inflammations of a low type, retrogressive in char- acter, and often occurring]without adequate cause, accompanied by certain marked tendencies to skin- affections, glandular enlargements, and bone-disease.
