the subject he found that such cases were far from uncommon, and concluded that like alcohol tea may be indulged in for a series of years without apparent ill consequences, but that sooner or later it undermines the health, and renders life miserable. As with alcohol he recognises two stages. The first stage was characterised by agreeable sensations in the stomach, moderate perspiration, quickened pulse and increased vivacity of mind and body. In the second stage there was irregular pulse, sometimes rapid, sometimes slow and intermitting, with palpitation and pains in the region of the heart--a vivacity of thought and action which is quite uncontrollable by the will, a painful insensibility to impressions of all kinds, twitchings of the muscles, disturbed sleep, frightful startings especially in the evening, irregular and sometimes cold perspiration, impaired appetite and defective circulation in the extremities. He concluded “that the immoderate use of tea and coffee produce a disease which bears a close resemblance to the _delirium tremens_ of whisky drinkers, and which is almost identical with the diseased state induced by the excessive indulgence of opium.” We now come to the opinion of the more recent authorities and a few remarks are necessary concerning the symptoms liable to result from excessive tea-drinking. In the _Boston Medical and Surgical Journal_ for September 10th, 1868, a writer Dr. Pratt explains the effects on himself of 12 grains of the alkaloid of tea. After two hours there was great physical restlessness, a very uneasy state of mind which has been described by Lehmann as “mental anguish.” Soon after there was marked tremulousness of the hands and arms; the hand trembled so violently that it was impossible to write with any regularity. The mind was excessively uncomfortable and anxious which admitted not of the slightest rest; it was in a state of most active and persistent thinking in spite of all attempts at forgetfulness. The severe symptoms lasted about two hours. Dr. Pratt spoke to one of the most prominent New England lady writers. She had tried green tea when pressed to do a large amount of writing in a short time. Some time after taking a large quantity of tea she felt as “if there was nothing left but her head which furnished rapidly language or ideas of the best quality, and in goodly quantity all night long.” The next day there was headache and more or less prostration.
