The next visitors to Tibet, and the first Europeans, so far as we know, who reached Lhassa, were the Fathers Albert Dorville and J. Grueber of the Chinese mission. They started from Pekin in June 1661, and travelled through China to Sining-fu, on the north-west frontier. From this place their route probably coincided with that of Huc and Gabet, who reached the same place from Eastern Mongolia. Their journey thence to Lhassa, Grueber describes as extending for three months through the deserts of Kalmuk Tartary, alternately sandy and mountainous. After some stay at Lhassa, they proceeded over the mountain range of "Langur, the highest existing, so that on its summit travellers can scarcely breathe on account of the subtlety of the air; nor can it be passed in summer, on account of the virulent exhalations of certain herbs, without manifest danger to life." Descending into the kingdom of _Necbal_, (Nepaul,) they passed some time at the capital, _Cudmendou_ (Katmandoo). Quitting Nepaul, they entered the kingdom of _Maranga_ (the Morung, or forest tract below the hills.) Proceeding by _Mutgari_ (Mooteeharee probably, in Tirhoot) to _Battana_ (Patna) on the Ganges, and thence to Benares, they reached Agra after 214 days' travelling from Pekin, exclusive of stoppages. Dorville died of fatigue shortly after the accomplishment of this heroic journey. The narrative, as abstracted in Kircher's _China Illustrata_, is adorned with some rather good cuts, most of which appear to have been derived from genuine sketches. In the fifteenth volume of _Lettres Edifiantes_ is an epistle dated from Lhassa, 10th April 1716, by Father Hipolito Desideri, a Jesuit. It relates his journey from Goa to Delhi, where he was joined by a brother missionary; thence by Lahore over the Pir Punjál to Kashmeer, and, after a residence of six months there, across the passes of the Himalayas, to Le or Ladakh, which he describes as the royal fortress of the kingdom of Great Tibet, or _Buton_. Whilst making arrangements to settle at Ladakh, and commencing the study of the language, the fathers heard for the first time of a _third_ Tibet, (viz. the Lhassa country, in addition to Little Tibet or Balti, and Great Tibet, or Ladakh,) and thought it necessary to proceed to explore it. The journey occupied them from August 1715 to March 1716. Desideri and his comrade are the only Europeans who have ever travelled from Ladakh to Lhassa; but, unfortunately, they give no particulars of their route except these dates, and even the great delay which they indicate is not accounted for.
