While Mormon speakers quoted Anthon as vouching for the mysterious writing, their writers were more cautious. P. P. Pratt, in his "Voice of Warning" (1837), said that Professor Anthon was unable to decipher the characters, but he presumed that if the original records could be brought, he could assist in translating them. Orson Pratt, in his "Remarkable Visions" (1848), saw in the Professor's failure only a verification of Isaiah xxix. 11 and 12:-- "And the vision of all is become unto you as the words of a book that is sealed, which men deliver to one that is learned, saying, Read this, I pray thee: and he saith, I cannot, for it is sealed: and the book is delivered to him that is not learned, saying, Read this, I pray thee: and he saith, I am not learned." [Illustration: Facsimile of the Characters of the Book of Mormon 072] John D. Lee, in his "Mormonism Unveiled," mentions the generally used excuse of the Mormons for the professor's failure to translate the writing, namely, that Anthon told Harris that "they were written in a sealed language, unknown to the present age." Smith, in his autobiography, quotes Harris's account of his interview as follows:-- "I went to New York City and presented the characters which had been translated, with the translation thereof, to Prof. Anthon, a man quite celebrated for his literary attainments. Prof. Anthon stated that the translation was correct, more so than any he had before seen translated from the Egyptian. I then showed him those which were not yet translated, and he said they were Egyptian, Chaldaic, Assyriac, and Arabic, and he said they were the true characters." Harris declared that the professor gave him a certificate to this effect, but took it back and tore it up when told that an angel of God had revealed the plates to Joe, saying that "there were no such things as ministering angels." This account by Harris of his interview with Professor Anthon will assist the reader in estimating the value of Harris's future testimony as to the existence of the plates. Harris's trip to New York City was not entirely satisfactory to him, and, as Smith himself relates, "He began to tease me to give him liberty to carry the writings home and show them, and desired of me that I would enquire of the Lord through the Urim and Thummim if he might not do so." Smith complied with this request, but the permission was twice refused; the third time it was granted, but on condition that Harris would show the manuscript translation to only five persons, who were named, one of them being his wife.
