"Well how is it?" he enquired, interestedly, as he looked about anxiously for a stand to place his test tubes in.
"Insoluble in water," was the answer as Dr. Seward held the flask to the light and scrutinized the particles which were floating, apparently uninjured, in the almost boiling water.
"See here, Doctor," said the Superintendent desperately, "You have more hands than I, just now; Do you mind stepping into the office and bringing me that paper on reactions? You will find it right in my desk."
Dr. Seward rose immediately and passed into the office. Standing by the open desk with the flask raised high in one hand, with the other he turned over a pile of papers in the somewhat disordered receptacle.
