though cases are said to have occurred both in the chemist's 

 laboratory, and the works in which it is commercially manu- 

 factured, of fatal attacks of bronchitis having been induced 

 from it. On the other hand, its dilute inhalation has been 

 confidently recommended as restorative in pulmonary con- 

 sumption ; and in my own observation of its constant use, 

 I have never in a single instance witnessed any bad efi'ects. 



As an antiseptic, Labarrhaque's solution is equally effi- 

 cacious in purifying the tainted air extricated from soap- 

 boiling, bone-crushing, tallow rendering, from drains, cabi- 

 nets d'aissance, sewers, and night-chairs, and the like 

 unwholesome sources of effluvium. Assuming chlorine to 

 possess some specific power on malarious infecting matter, 

 which my own experience would seem to justify, its action 

 in this capacity may be supposed to reside in the decom- 

 position of the associated aqueous vapour, for which it has 

 a great affinity, with a resulting formation of chloric and 

 hydrochloric acids, and an inert deposit of putrescent par- 

 ticles. 



The preparation before you was made by simply passing 

 chlorine through a saturated solution of fresh lime-water, 

 with a little additional lime in suspension, and may be 

 largely diluted for ordinary disinfecting purposes. The 

 solution of chloride of soda is readily made by decomposing 

 this fluid with the carbonate of soda, and possesses deodo- 

 rant properties well suited for the dressing of sloughing 

 and ulcerated surfaces, though in medical efficacy inferior 

 in many cases, where an astringent is likewise wanted, to 

 the diluted liquids of Ledoyen and Burnett. 



The simplicity, efficiency, and inexpensive character of 

 these chlorurets, when prepared on a large scale, give them 

 a very strong recommendation ; and were they sold at about 

 one-third their present retail price, we might hope to intro- 

 duce them into general use. There is, too, I see, advertised
