Blowing Air Under the Skin.
When the muscles of the shoulder have wasted away, constituting the condition termed “sweeny,” air sometimes is blown under the skin to give the part a plump condition. This trick is easily detected, for when the hand is passed over the inflated part it crackles (crepitates) showing the presence of air under the skin (emphysema). The same trick is practised to make an old horse appear younger than he really is, the hollow’s over the eyes being blown up by means of a hollow needle, quill or straw passed through the skin. For low hip and atrophy of the shoulder muscles we have also known tricksters to inject a two per cent solution of phenol under the skin and then thoroughly massage the part.
