    may co-exist with a percussion-sound muffled in tone but far from absolutely dull. /?. When patients, who are put under the influence of chloroform with a view to paracentesis, struggle and scream, or simply breathe deeply, parts which before were wholly dull to percussion become resonant; yet, puncture these parts, and liquid freely flows, y. When pleural effusion has been removed by absorption or drainage, the dulness continues to be almost or quite as great as ever, so long as the lung remains unexpanded. Class III.—Metallic Bt-sounds. I. The Metallic Eing is sometimes heard on percussion of pneumothorax, and of very large pulmonary cavities containing air. II. The sundry causes of Cracked-Pot sound have been already set forth (p. 73). 5[ 11.—PULMONARY PERCUSSION RBSISTBNCE. Whatever diminishes the elasticity of the part percussed increases the sense of resistence to percussion. Wherefore massive consolidation of the lung, liquid pleural effusions, and extreme distension of lung or pleura with air, afford a feeling of resistence more or less increased.
