The printing of his Hebrew Lexicon was completed in 1854.
The reader will scarcely be prepared for the relinquishment of this mission, which took place early in 1856, though not in consequence of failing success.

The Armenian and Jewish missions, at their united annual meeting in the spring of 1855, recommended that the Board relinquish to some other society the Jewish stations of Salonica and Smyrna.

Constantinople, as such a station, had been practically relinquished some time before.

At a conference of missionaries in Constantinople in November of that year, on occasion of a visit from the Foreign Secretary of the Board, the subject was carefully considered, and the question was decided according to the personal convictions of the brethren in the Jewish mission.

The result was in favor of relinquishing the Jewish field to the English and Scotch Societies; and of the younger members of the mission devoting their strength to the Armenian field, the exclusive right to which had been conceded to American missionaries by the general consent, as it were, of Protestant Christendom.
