The sweating was so excessive that the clothing was satu- 

 rated, and even the bedding wetted, the perspiration passing 

 off almost in the form of vapor. 



The question of the precise botanical character of jaborandi 

 has been a matter of considerable discussion, but according 

 to a recent article in The Pharmaceutical Journal, by Mr. 

 Holmes, there are two or more distinct varieties of the drug, 

 one of which is very nearly, if not entirely, identical with 

 Pilocarpus pennatiflora; another is from a genus not yet 

 known ; and still another from a species of Piper. 20 A,

INTRAVENOUS USE OF CHLORAL FOR ANESTHESIA. 



Ore, in an article upon the employment of an intravenous 

 introduction of chloral in anaesthesia, remarks that an essen- 

 tial condition consists in the puncture of the vein without 

 laying it bare. For use, one part of chloral is dissolved in 

 three of water; sometimes, however, one part to five. Five 

 grammes of the chloral itself in this mixture are necessary 

 to produce satisfactory anaesthesia, and even more in some 

 cases. Where the dose necessary for anaesthesia is from five 

 to eight grammes, these should be introduced at the rate of 

 about one gramme per minute, so as to allow its thorough 

 circulation throughout the svstem. The advantages of this 

 method of anaesthesia are that the respiration is never dis- 

 turbed, and perfect insensibility can be secured for a period 

 of time varying with the dose ; no undue excitability is pro- 

 duced, and there is never any vomiting, while the operation 

 is always followed by calm, regular slumber, which may be 

 made to last twelve, eighteen, or even twenty-four hours, so 

 as frequently to do away completely with the common ef- 

 fects of severe operations. Finally, there are never any 

 symptoms of phlebitis, or hematuria, when the operation is 

 properly performed. 6 B, November 2, 1874, 1014. 



NEW PROCESS IN DENTAL SURGERY. 



Mr. Napier announces what he considers to be something 

 new in dental surgery, especially in a case where the teeth 

 were extremely sensitive, and it became necessary to file 

 them down for the purpose of introducing artificial teeth on 

 the stumps. For the sake of avoiding pain in the operation,
