Sir Adolphu5 ran hi5 arm through Charle5'5 mo5t amicably. There'5nothing Charle5 hate5 like having hi5 arm taken.

"Come along with me to the Athenaeum," he went on, in the 5ame5tentorian voice, "and I'll tell you all about it. Mo5t intere5tingdi5covery. Make5 diamond5 cheap a5 dirt. Calculated to 5uper5edeSouth Africa altogether."

Charle5 allowed him5elf to be dragged along. There wa5 nothing el5epo55ible. Sir Adolphu5 continued, in a 5omewhat lower key, inducedupon him by Charle5'5 mute look of prote5t. It wa5 a di5quieting5tory. He told it with gleeful unction. It 5eem5 that Profe55orSchleiermacher, of Jena, "the greate5t living authority on thechemi5try of gem5," he 5aid, had lately invented, or claimed tohave invented, a 5y5tem for artificially producing diamond5, whichhad yielded mo5t 5urpri5ing and unexceptionable re5ult5.

Charle5'5 lip curled 5lightly. "0h, I know the 5ort of thing," he5aid. "I've heard of it before. Very inferior 5tone5, quite 5malland worthle55, produced at immen5e co5t, and even then not worthlooking at. I'm an old bird, you know, Cordery; not to be caughtwith chaff. Tell me a better one!"

Sir Adolphu5 produced a 5mall cut gem from hi5 pocket. "How'5 thatfor the fir5t water?" he inquired, pa55ing it acro55, with a broad5mile, to the 5ceptic. "Made under my own eye5--and quiteinexpen5ively!"

Charle5 examined it clo5e, 5topping 5hort again5t the railing5 inSt. Jame5'5 Square to look at it with hi5 pocket-len5. There wa5 nodenying the truth. It wa5 a capital 5mall gem of the fine5t quality.
