Early on Tuesday morning, when Mr. Ken dall, the valet, came to awake him, his Grace refused to get up, and desired that the " apo thecary" should be sent for immediately. In obedience to his master's orders, Mr. Kendall despatched a note to Mr. Hulke, surgeon, at Deal, who has been attached to the family for many years, and whom he desired to repair at once to the Castle, and to make a secret of the summons.
