edly. of its supposed safety and of unscrupulous operators. In larger 

 cities the gas business is done where they make extracting teeth a specialty, 

 and patients are rushed through the mill regardless of health, nerves or 

 condition. In smaller towns it is impracticable and non-paying, and the 

 gas is liable to be stale or impure. Under either circumstance it is exces- 

 sively uncleanly to inhale from a bag that others have exhaled their foetid 

 breath into. 



Only a small portion of gas is taken up by the lungs at each inhalation, 

 and all that is exhaled is carbonic acid gas, which soon poisons all that is 

 in the bag. Hence, it is not improper to infer that the patient, when in- 

 sensible, IS as near asphyxia as ansesthesis. 



Syncope is a misnomer for the alarming symptoms produced by ether. 

 When death results from inhaling ether the heart continues to beat several 

 minutes after respiration has ceased, thereby giving due warning of dan- 

 ger and making ether comparatively safe. 



Loud breathing (snoring) proceeds from inertia of the palate, and should 

 be carefully watched. If it stop suddenly stop the ether and apply restor- 

 atives. 



Chloroform is more volatile, more powerful, and the danger exists in 

 sudden action upon the heart. Experienced, unhesitating operators will 

 readily detect danger when the patient has taken a few inhalations. 



The colleges and hospitals have adopted as a standard, one part chloro- 

 form to two or three of ether, the mixture being more active and more 

 i-eadily thrown off. There is no authentic case where any patient has died 

 from anaBSthesis by the use of this mixture. There is danger that a cheap 

 and supposed-to-be safe anaesthetic will be introduced, in which case x\mer- 

 ica is liable to become a toothless community. 



Moral — Don't allow your teeth to require extracting.

THE STE. GENEVIEVE COUNTY COPPER MINES. 



The copper mines described at length below are now becoming quite 

 widely known, consequent on shipment East of their ores and the recent 

 construction of a copper furnace at Ste. G-enevieve, in which the copper ore 

 is now reduced to the condition of black copper, and in that condition ship- 



p:3d eastward for refinement.
