three o'clock
The idea of sunstroke was so confirmed by the symptoms when he was brought to the hospital that no one thought of anything else . '' `` How soon ? '' asked the nurse . `` To-morrow -- three o'clock . '' And the next afternoon , Cardo 's head was thoroughly examined , with the result that Dr. Belton soon found at the back of the skull near the top a small but undoubted indentation . `` Of course , '' he said , `` we must have been blind not to guess it before ; but we are blind sometimes -- very blind and very stupid . '' Cardo was kept under the influence of a sedative that night , and next day Dr. Belton , with the promptness of action which he now regretted he had not sooner exercised , procured the help of one of the most noted specialists in Sydney , and an operation was successfully performed .
