8), and a subsequent appropriation of the mountain to a heathen worship is much less remarkable. No reason is to be found, however, in the fact, that when the Lord spoke to Moses he lived in Midian with Jethro, to warrant the placing of the mountain of the Law in Midian, for that it nowhere said. We only know, that Raphidîm, where Jethro visited Moses from Midian, lay in the territory of the Amalekites, as they here made the attack. Eusebius, who (_s. v._ Ῥαφιδίμ) expressly refers Raphidîm and Choreb to Pharan, says (_s. v._ χωρήβ) that this mountain of God lay in _Madian_. Also in _Itinerar. Antonini_, c. 40, Pharan is placed in _Madian_. Would that these observations, in which I believe I have touched upon almost all the more important grounds of their esteemed author, may prove to him, how high a value I set upon each of his opinions, as those of a more competent judge in this field of research than any other. Ritter’s long, well-known tact for the truth in such questions would have caused me to have less faith in my own view than all the grounds he produces, which are generally to be confuted, as it appears, if I had not in _this_ case the advantage of a personal inspection of the localities, unprejudiced by any former opinion, which could make it less independent of former writers, than it is possible for him to have. NOTE B. (Letter XXXIII. p. 354.) Robinson gives the distances from Ayûn Mûsa to the crossing point of Wadi Shebêkeh, and Wadi Taibeh (vol. iii. Part II. p. 804); these correspond tolerably well with Burckhardt (pp. 624, 625), who continues the distances up to Wadi Firân; these last, if we take his round across Dhafari into consideration, are confirmed by my own. The calculation in Robinson (p. 196), however, does not comprehend the four or five hours’ longer way round from the convent, through Wadi e’ Sheikh; for Burckhardt went over the Nakb el Haui in eleven hours to Firân, while we required sixteen, subtracting the little way through the Ktesse valley. From this the distances are thus proportioned:--From Ayûn Mûsa to Ain Hawârah, eighteen hours and thirty-five minutes; thence to Wadi Gharandel, two hours, thirty minutes (not an hour and a half to two hours, as it is calculated in the text, from the camp of Robinson); to the end of the valley, near Abu Zelîmeh, seven hours, twelve minutes; thence to the sea, one hour; to Wadi Shellâl four hours, fifteen minutes; to Firân, thirteen hours, forty-five minutes; to the convent, sixteen hours. The camp in the Wilderness of Sin, Robinson cannot refer more to the south than to the end of the Wadi Shellâl; because the people, according to him, here left the Wilderness of Sin, as necessarily Alus falls with him beyond Firân. On the other hand, according to my opinion, the camp at the sea is not only not different from that at the entrance of the valley near Abu Zelîmeh, but the Wilderness of Sin of Exodus, which reached to Sinai, and ended with
