mufcle, with lofs of power in each, expeftation of immediate deatli fuccefflvely oc- 

 curred, and in a degree fo alarming as to render it difficvilt to remove the apprehenfions - 

 of tVie young lady's friends. 



Thefe fits appeared to have been certainly produced by the fpccific power of the gas ; 

 and other trials caiuioufly made by' ladies who were acquainted with all the previous 

 fafts, and fubjeft to hyfleric affeftions, produced effefts which tended to confirm the 

 above inference. 



I cannot attempt, with any hope of precifion, to give an anaI)Tis of the other parts of 

 the Doftor's pamphlet, and ftill lefs can I think ol making any remarks on a fubjeft fo 

 new, fo flriking, and at the fame time fo obfcure. He feems to be of opinion that the 

 blood may impart to the folids various compounds of oxygen, azote, &c. which are quite 

 unknown to our chemiflry ; — that the nerves may require one kind of fupply and the 

 mufcles another; — that the gas in queftion ctmimunicaies the principle which gives energy 

 to the nerves ; — that of this principle the fyftem of nervous patients pofTeffes a morbid 

 excefs, but that the fyftem of paralytic fubjefts is defeftive in that refpeft. From thefe 

 and other reafonings it was expefted to be beneficial in the latter difeafe, and the few 

 cafes yet tried are very ftrong in confirmation of this indu6iion.

A Chemical Examination of the Bath Waters, by George Smith Gibbes, M. D.

Great deal of attention feems neceflary in afcertaining to any certainty the degree 

 of heat of the Bath waters. So many caufes occur to lower their temperature a few 

 degrees, that their precife heat at any one part of the Bath will not be found to anfwer 

 exaftly with any other part. After pumping a confiderable time at the King's Bath, the 

 temperature is generally from 114 of Fahrenheit to 117, or even 118. The hot bath 

 is nearly of the fame temperature with the King's bath. The crofs bath is of a fome- 

 what lower temperature, from 110 to 112. As the pumps lead immediately from the 

 fprings, the temperature of thefe waters can be better afcertained from them than from 

 the baths. 



Twelve grains of nitrate of filver were added to fix ounces of the King's bath wa- 

 ters, and feven grains of precipitate were left to the filtre. No precipitation was ob- 

 fcrved on the addition of more nitrate of filver to the filtered liquor. To four ounces 

 of this liquor were added two drachms of a faturated folution of acetate of barytes, 

 - and twerty grains of precipitate remained on the filtre. There was no farther precipi- 

 tation
