The Abou-Hannes has been placed by Latham, in his _Index Ornithologicus_, under the name of _Tantalus Æthiopicus_; but he does not speak of Bruce’s conjecture respecting its identity with the ibis. The travellers before and after Bruce appear to have all been in error. Belon thought that the white ibis was the stork, in which he evidently contradicted all testimony on that head. No person has adopted his opinion in this matter, excepting the apothecaries, who have taken the stork for an emblem, because they have confounded it with the ibis, to which the invention of clysters is attributed[357]. Prosper Alpinus, who relates that this invention is due to the ibis, gives no description of this bird in his Medicine of the Egyptians[358]. In his Natural History of Egypt, he speaks of it only after Herodotus, to whose account he only adds, without doubt from a passage of Strabo, which I shall mention farther on, that that bird resembles the stork in size and figure. He mentions his having been informed that white and black ones occurred in abundance on the edges of the Nile; but it is evident from his very expressions, that he did not believe it had been seen there[359]. Shaw says of the ibis,[360] that it is at the present day excessively rare, and that he has never seen it. His _Emseesy_, or ox-bird, which Gmelin very improperly refers to the Tantalus Ibis, is of the size of the curlew, with the body white, and the beak and feet red. It frequents the meadows, where it follows the cattle; its flesh is not well tasted, and corrupts quickly. It is easy to see that this is not the Tantalus, and still less the Ibis of the ancients. Hasselquist was not acquainted with the white Ibis nor with the black one, his _Ardea Ibis_ is a small heron, which has the beak straight. Linnæus had acted very properly in placing it among the herons, in his tenth edition; but he erred, as I have said, in transporting it afterwards as a synonym to the genus _Tantalus_. Demaillet[361] conjectures that the ibis might be the bird peculiar to Egypt, and which was named Pharaoh’s Fowl (_Chapon de Pharaon_), and at Aleppo _Saphan-bacha_. It devours serpents. There are of them white, and white and black; and it follows, for more than a hundred leagues, the caravans which go from Cairo to Mecca, for the purpose of feeding upon the carcases of animals which are killed during the journey, while at any other time there is not one seen along this route. But the author does not consider this conjecture as certain; he even says, that we must give up understanding the ancients, when they have spoken so as not to be understood. He ends with concluding, that the ancients have perhaps indiscriminately comprehended under the name of Ibis, all birds which rendered to Egypt the service of clearing it of the dangerous reptiles which this climate produces in abundance, such as the vulture, the falcon, the stork, the sparrowhawk, &c.
