bitter almonds. It may prove deadly to man or dog in a 

 dose of fifteen drops, though most commonly it enters the system 

 by inhalation. In animals the prominent symptoms are convul- 

 sions and paralysis, supervening on a period of weak circulation 

 and pulse, and blueness of the visible mucous membranes. The 

 characteristic odor resembling the oil of bitter almonds exhales 

 from the lungs and skin. In man there are dilatation of the 

 pupils, blueness of the lips and nails, pallor of the face, weak 

 pulse, slow breathing (often in the end Cheyne-Stokes respira- 

 tion), a dark maroon or port wine color of the urine, and ambly- 

 opia. In the chronic cases the skin is yellowish, and there are 

 weariness, a dragging walk, headache, morning anorexia, 

 drowsiness, giddiness, numbness of the hands or other parts and 

 emaciation. The blood is chocolate color with red globules re- 

 duced in size, in number and in haemoglobin, but containing an 

 excess of carbon dioxide. The brain is often congested and the 

 gastro-intestinal mucosa like the skin may be yellow (from al- 

 leged formation of picric acid). In chronic cases disseminated 

 sclerosis may be seen. 



In treatment emesis, purgation, stimulants (ammonia, cam- 

 phor), galvanism, sinapisms to the chest, and phlebotomy, with 

 injection of normal salt solution, may be resorted to, as in aniline 

 poisoning. 



POISONING BY CARBON BISULPHIDE. 



Used to kill insects in grain, etc., in barns. Locally anaesthetic, and irri- 

 tant. Inhaled, toxic, causing excitement; anaesthesia, collapse. Large 

 doses, excitement, reckless movements, incoordination, giddiness, sleep, 

 stertor, paraplegia. Small doses, weakness, emaciation, tremors, paraplegia, 

 polyuria, mellituria ; convulsions, death. Distortion and varicosity of axis 

 cylinder, and unequal staining of cytoplasm. Treatment: pure air, good 

 diet ; massage, electricity, tonics, phosphorous. 



This agent is largely used in vulcanizing and other factories 

 where the employes are liable to suffer, and also in granaries, 

 barns, etc., for the destruction of insects in grain and other 

 objects and where animals are liable to suffer. 



Locally it acts like chloroform, when confined to the surface, as 

 under a glass or covering, producing very active irritation with 

 anaesthesia.
