A place named Tai-garee appears in a route from Tunis to Kashna, communicated by Mr. Magrah, at fifteen journies from Gadamis.[44] It appears highly probable that this is the same place with Teghery in Fezzan: but the distance arising on the fifteen journies falls very short of the position of Teghery, placed as above. Could this point be ascertained, it would operate as a check on the position of Mourzouk; and I cannot but suspect, that this capital is somewhat more to the west, or north-west, than it now stands in the Map. These facts are particularly noticed here, that future geographers may inquire, whether the route of the Tunis caravan, to Soudan, passes through Teghery in the western skirt of the country of Fezzan; as I conceive it doth: and also that there is some error in the combination of the geographical context, between Tunis, and the eastern positions, which prevents the closing of the lines, to the aforesaid town of Teghery. One cannot dismiss the subject of Fezzan, without remarking, that the observations of Mr. Horneman have added another proof of its being the country intended by the ancient authors, for that of the Garamantes. For he has shewn us, that the black rocky Desert, the continuation of the _black Harutsch_, passes between Fezzan and Tripoly, and extends yet farther west, towards Gadamis; and as Pliny places the _Mons Ater_ in this position, with a desert and the cities of the _Garamantes_ beyond them, these cities cannot well be any others than those of Fezzan. (See above, page 151). I shall also mention, in its place, another circumstance brought to light by Mr. Horneman, concerning the _Troglodytæ_ mentioned by Herodotus, in the neighbourhood of the Garamantes; and which induces a very strong belief that the people bordering on the south-east of Fezzan, are meant.

Since the construction of the General Map, in 1798,[45] much new matter has appeared in the Travels of Mr. Browne: and to these are now to be added, the observations and inquiries of Mr. Horneman. These important notices will be found mutually to explain and confirm each other, as far as they go, over the same ground; and which is to a very considerable extent.
