If, however, the influence of alcohol be pushed beyond this point, the manifestations of mere exaltation of function give place to grave perversion of the processes of life. A gradually increasing vertigo is associated with obscured intelligence, dulled imagination, blunted and confuted perception, disjointed ideation, and incoherent speech. The recollection grows indistinct, the will purposeless. Now the baser passions are aroused; evil impulses and illusions of all kinds sway the drunken man. All control of conversation and action is lost. Reason is replaced by delirium, and he becomes a maniac, dangerous alike to himself and to others, liable upon some sudden impulse to commit the most atrocious crimes.

The countenance betrays the profound disturbance of the intellectual and moral nature: its expression is changed, its lines are blurred; the flush deepens, the veins are distended, the arteries pulsate visibly, the gaze is staring, the pupils contracted. The respiration, at first quickened, becomes irregular. The heart's action is rapid and bounding, and sometimes there is palpitation. Somnolence soon deepens into an invincible desire to sleep. At this point great muscular relaxation not infrequently occurs in connection with vomiting, profuse sweating, and dilatation of the pupils.

Muscular movements are irregular and uncertain, the gait vacillating and staggering; the movements of the superior extremities, wanting in precision, become trembling and awkward. At the same time speech becomes embarrassed. Articulation is difficult and imperfectly executed. At length standing becomes impossible; the drunkard, profoundly poisoned, sinks helplessly to the ground, and not infrequently the control of the sphincters is lost. The development of this condition is accompanied by a gradual perversion of general and special sensibility. Dull headache, ringing in the ears, phosphenes, and other disturbances of vision, hallucinations of taste and smell, are followed by abrogation of the special senses. Loss of cutaneous sensibility, beginning at the extremities, invades the whole body, and finally the subject sinks into more or less profound coma, from which it is no longer possible to arouse him. Muscular resolution is complete, sensation is lost; the face is now bloated, deeply flushed, sometimes livid, sometimes ashy pale; the pupils are dilated; the temperature below normal; the respiration stertorous and accompanied by abundant mucous râles. The pulse is feeble, fluttering, the surface covered with sweat, and involuntary evacuations take place.

VARIETIES.—Three varieties of acute alcoholism are recognized by Lentz—the expansive, the depressive, and the stupid. The first is characterized by gayety, self-satisfaction, and content. The drunkard, smiling and happy, is satisfied with the present and full of hope for the future. The second variety is characterized by sadness and melancholy. The drunkard becomes sombre and taciturn; if he talk at all, it is to bewail his misfortunes and to recount his mishaps. In the third variety the period of excitement is wanting and the drunkard passes rapidly into a condition of stupor.

Great as are the modifications of the course of acute alcoholism under different circumstances and in different individuals, it is evident, upon close investigation, that its phenomena—and especially those which relate to the nervous system—manifest themselves in a progressive series more or less constant in the majority of persons. This series includes three well-characterized periods: 1. The stage of functional exaltation of the nervous system; 2. The stage of functional perversion; 3. The stage of depression.

We may, then, recognize the degrees of acute alcoholism corresponding to these stages.14 Of these, the first scarcely goes beyond the stage of excitement already described, and if the dose have been moderate or its repetitions not too long continued, the symptoms gradually subside, leaving perhaps no sequels beyond slight headache, tinnitus aurium, some degree of muscular relaxation, and mental depression.

14 These stages correspond to the three degrees of alcoholic intoxication recognized and described by German writers as Rausch, Betrunkenheit, and Besoffenheit. To these may be added the prodromic period, designated as Weinwarme Zustand. These three degrees are known to the French as l'ivresse légère, l'ivresse grave, and l'ivresse suraiguë.

The second degree is characterized by partial abolition of intelligence, of general and special sensation, and of motor power. Hence incoherent speech, extravagant actions, blunted perceptions, hallucinations and delusions, inco-ordination of movements, a reeling gait, and not rarely vomiting and involuntary discharges of urine and feces. This degree of acute alcoholism usually ends in deep sleep with abundant perspiration, to which succeed great lassitude and depression, accompanied by much gastro-intestinal derangement, of which the symptoms are inability to take food, coated tongue, viscid mouth, foul breath, repeated vomiting, and occasionally diarrhœa. These sequels are less serious in those individuals accustomed to excesses than in others.

In the third degree the subject falls by gradual stages or abruptly into more or less profound coma. The abolition of intelligence, sensation, and motion is complete. The face is now swollen, livid, or pale, the pupils dilated, the respiration stertorous, the pulse feeble, often slow, sometimes imperceptible, the surface cool and often bathed in sweat. The man is dead drunk. The symptoms are now of the gravest kind. It is no uncommon occurrence for this condition to end in death.

Well characterized as these three degrees of alcoholic intoxication are, they are not, when occurring successively in the same individual, separated by abrupt lines of demarcation. On the contrary, the evolution of the symptoms is from the beginning to the close a gradual and progressive one.
