[6] This experiment every urchin has repeatedly made, to his own edification and the annoyance of his family. [7] Those in a somnambulistic state communicate with, and can receive impressions from, the operator alone. [8] No better confirmation could be had of the fact, than the patient's own asseveration. OUR BIRTH-DAYS. THE anniversary of our birth-days is always an interesting period, and should be noticed accordingly. Each of such days is a mile-stone on the road of life, reminding us of the rapid rate at which we have been advancing on its journey, and approaching its close. It is true that in life's _morning_, these mile-stones appear to be farther apart than they do in later years; still, they are days of hope and promise. Thousands are then rejoicing that they are one year nearer to the boasting age of twenty-one, when a young man feels himself lord of his own actions, and glories in his liberty. To thousands of the fairer part of creation, these annual monitors are welcome, as harbingers of the day when they shall shine in the ball-room or circles of fashion; attract all eyes, and command all attention; or perhaps fasten some silken chain around the heart of an individual admirer, and lead him in delightful captivity. To other thousands of the same sex, the anniversary will tell a tale of sadness; of departed hours and departed charms; of withered roses and withered hopes; when the looking-glass has lost its magic power, and speaks nothing save in the plain language of unwelcome truth and soberness. Thousands are reminded that many of the intervals, between one mile-stone and another were distinguished by lovely landscapes and countless beauties; by health and enjoyment--by joy and gladness of heart. To thousands of others, such intervals have been gloomy and cheerless; without the consolations of friendship, the comforts of society, or the flattering promises of hope. Surrounding prospects have only increased the gloom of the mind, and made the heart sick.
