through the country without difficulty, so that patients 

 could he removed there and bathe in loco." 



Dr. Morton found on analysis, that the waters contain 

 a considerable quantity of calcareous matter, and that the 

 tufa which it deposits on the border of the springs, is a 

 carbonate of lime. They appear to arise from the moun- 

 tain limestone, and thus to hold a geological position sim- 

 ilar to that of the hot springs of Great Britain, most of 

 which rise from strata below the coal, and hence from, r 

 through the limestone. 



SULPHUREOUS THERMAL SPRINGS. 



About four miles below Matah at the forks of the Te> 

 hasserim, and a few miles north of the latitude of Tavoy, 

 n-e hot springs highly charged with sulphuretted 

 hydrogen gas, so readily recognized by its smell which is 

 precisely that of the washings of a gun barrel ; the odor 

 in both instances being produced by this same gas. AJJ 

 the stones in the springs are of a bright brass color, pro- 

 duced apparently by the deposition of the sulphur; and 

 although the virtues of these waters are hidden from man, 

 they appear to be well known to the beasts of the forest. 

 To jud^e from the tracks around in tie morning, the most 

 rruous parties are held here every night. The deli- 

 cate little tread of the chevrotain and barking deer, are 

 seen side by side with the massive steps of the elephant 

 and rhinoceros; and the tiger, and the leopard seem to 

 side their fierceness, and peaceably walk away satis- 

 fled with a draught of the much coveted beverage. 



Dr. Heifer said these springs belonged to " the class of 

 sulphun >us mineral waters, tinged slightly with chaly- 

 beate, like the water of Brighton." Their heat above the 

 acre is not great. IVlr. Bennelt at a recent visit, 

 found the thermometer to rise in the hottest spring to on- 

 ly 119°. They rise from the slate rocks, like the warm 

 gs of a considerable part of Germany. 



SALINE THERMAL SPRINGS. 



On the margin of the granite range east of Tavoy, 

 either near the junction of the slate and granite, or in the
