Authorities.

1 , Sir J. Y. Simpson, Pharm. Journ., 24, 416; 2 , Nunneley, Brit. Med. Journ., 1867; both are statements of the effects of the vapor.

HEAD

• Full pulsation in head and limbs, 2.
• Full and hot sensation in head (after one hour and a half), 4.

STOMACH

• Sinking and nausea at the stomach (after one hour and a half), 2.

ABDOMEN

• Feeling of distension, 2.

RESPIRATORY ORGANS

• Since inhaling the vapor, a relaxed condition of the bronchial mucous membrane, with expectoration every morning of three or four lumps of carbonaceous mucus, and some during the day, has altogether disappeared, and the little irritation of the membrane has also gone, 2.

HEART AND PULSE

• The depressing influence upon the heart greater than that of Chloroform, 1.
• Failing in the action of the heart, which became weak, and not more than forty-eight per minute, with great lassitude in the limbs (after one hour and a half), 2.
• The pulse becomes extremely feeble and weak, 1.
• Pulse weak and rapid during the greatest degree of anæsthetic sleep, 1.

GENERAL SYMPTOMS. [10.]

• Great muscular lassitude and indisposition to move, 2.
• Its primary effects are similar to those of Chloroform, but it takes a longer time to produce the same degree of anæsthesia, and generally a longer time to recover from it, 1.

FEVER

• Sensation of heat all through the system, 2.

SLEEP AND DREAMS

• Sleepiness, with a sort of passive wish to proceed with the inspiration, but as if even this were too much trouble, 2.
• Bad night, with little continuous sleep till morning; lay half dreaming, with a hot skin, a swimming feeling in the head, nausea at the stomach, a very dry tongue sticking to the palate, a taste of the Tetrachloride, and a weak pulse, with a feeling like sea-sickness; restlessness, with a disinclination to move, 2.

• When the vapor is inhaled it causes so great irritation of the throat, that few can persevere in breathing it for such a length of time as to induce anæsthesia. I have latterly, however, seen it inhaled perseveringly until this state, with all its usual phenomena, followed; and without excitement of the pulse or subsequent headache. When I myself attempted to inhale the Chloride of hydrocarbon, it produced an extreme degree of acrid irritation in the throat, which did not disappear entirely for many hours afterwards, 3.
