The 9th 'experiment, which my fhort ftay at 

 Matlock would not allow me leifure to repeat, af- 

 fords a prefumption that the water is not pofTefled of 

 any Simulating powers 3 for the fmall increafe of 

 quicknefs in my pulfe, on drinking half a pint of 

 it, may be afcribed more to the quantity received 

 -into the ftomach, than to the heating quality of 

 the water, 



The Bfiftol and Matlock waters appear to refem- 

 ble each other, both in their chemical and medici- 

 nal qualities. I have examined and compared them 

 together by the tell mentioned above, and fo far 

 as fuch trials may be be deemed conclufive, there 

 feems to be no other than the following flight dif- 

 ference between them, 



Briftol water becomes a little more milky on the* 

 addition of a folution of fixed alkali, and of Saccha- 

 rura Saturni than that of Matlock;, the former alio 

 weighs near a grain in a pint heavier than the latter. 

 Is it not to be lamented therefore, that fo little at- 

 tention is paid to Matlock, even by the phyficians 

 who refide in the neighbourhood of it? In hectic, 

 cafes, hsemoptoes, the diabetes* and other diforders, 

 in which the circulation of the blood is rapid and I 

 irregular, I fhould apprehend that Matlock water, . 

 on fome accounts, claims the preference to that of 

 Briftol ; for it is lefs difpofed to quicken the. pulfe,. 

 and may therefore be drunk- in larger quantities.. 

 But it muft be acknowledged that the climate of: 

 Briftol is fuperior to that of Matlock, a circumftance 

 of the highefl: importance to confumptive patients,, , 

 Situated in a deep though delightful valley, and fur- 

 rounded by very high mountains, the fun difappears
