A strong scalpel is now introduced at the coronary opening, with its cutting-edge outwards, and is gradually passed down the opening made by the saw.

With the cutting-edge of the knife forward, it is gradually reached round and under the hindermost end of the cartilage, and theposterior half of the cartilage separated from underlying structures, and at the same time excised by one clean cut forwards.

Using the second sage-knife in a similar manner, the cutting-edge this time backwards, it is reached in front of the cartilage, whose anterior half is then excised by a careful cut backwards.

So the American business man has grasped his opportunities and used them and developed them and invented about them, thought them into lines of success, and thus has developed into a new business man, with a vigor and effectiveness and a cutting-edge that has never been equalled anywhere else.
