xxxiv INTRODUCTION, 



gant remains here, but in this I was difappointed ; I found 

 nothing remarkable but the baths of very warm water* 

 without the town ; in thefe there was a number of fifh, 

 above four inches in length, not unlike gudgeons. Upon 

 trying the heat by the thermometer, I remember to have 

 been much furprifed that they could have exifled, or even not 

 been boiled, by continuing long in the heat of this medium. 

 As I marked the degrees with a pencil while I was myfelf 

 naked in the water, the leaf was wetted accidentally, fo that I 

 miffed the precife degree I meant to have recorded, and do 

 not pretend to fupply it from memory. The bath is at the 

 head of the fountain, and the ftream runs off to a confider- 

 able diflance. I think there were about five or fix dozen of 

 thefe filh in the pool. I was told iikewife, that they went 

 down into the ftream to a certain diftance in the day, and 

 returned to the pool, or warmefl and deepen: water, at 

 night. 



From Feriana I proceeded S. E. to Gafsa, the ancient Capfaf, 

 and thence to Tozer, formerly Tifurus |J. I then turned 

 nearly N. E. and entered a large lake of water called the 

 Lake of Marks, becaufe in the paffage of it there is a row 

 of large trunks of palm trees let up to guide travellers in 

 the road which croffes it. Doctor Shaw has fettled very 

 diftmctly the geography of this place, and thofe about 

 it. It is the Palus Tritonidis ^', as he juftly obferves ; this, 

 was the mod barren and unpleafant part of my journey
