He bent forward in his chair, talking earnestly and rapidly. There was no time to be lost, since the disease was apt to take sudden leaps forward; at this stage every day was of value; the enemy must be attacked before he had made good his hold. There was a new treatment which, within his own experience, had had excellent results.
