    Respiration increased but regular and free, unless interfered with by emotional causes or by direct irri- tation of the anaesthetic, inducing cough, holding of breath, deglutition movements, retching or vomiting. Pupils dilated. 2. Stage of Light Anaesthesia. Complete loss of consciousness. Delirium; articulate speech passing into unintelli- gible muttering. Respiration still deeper and quicker than normal; often irregular and impeded by General tonic muscular spasm, deglutition, closure of glottis, spasm of jaws, etc. Clonic muscular spasm. Reflexes still persist; but motor results of stimuli devoid of purposive character. Inarticulate phonated (expiratory) sounds. Coughing, retching, vomiting. Heart's action still excited (much dependent on character of breathing). Pupils smaller. 3. Stage of Deep Anaesthesia or Narcosis. Relaxation of most muscles. Breathing regular, often softly snoring or ster- torous. Decrease of respiratory changes; fall of temper- ature. Increase fall of blood-pressure. (Chloroform.) Heart's action weakened, variable degree of cardiac dilitation.
