The objects of the Scriptural Knowledge Institution are set forth as follows: "To assist day schools and Sunday-schools in which instruction is given upon scriptural principles," etc. By day schools conducted on scriptural principles, they mean "those in which the teachers are believers; where the way of salvation is pointed out, and in which no instruction is given opposed to the principles of the Gospel." In these schools the Scriptures are read daily by the children. In the Sunday-schools the "teachers are believers, and the Holy Scriptures alone are the foundation of instruction." The second object of the Institution is "to circulate the Holy Scriptures." In one year four thousand three hundred and fifty Bibles were sold, and five hundred and twenty-five were given away; seven thousand eight hundred and eighty-one New Testament were sold, and one thousand five hundred and seventy-four were given away; fifty-five copies of the Psalms were sold, and thirty-eight were given away; two thousand one hundred and sixty-three portions of the Holy Scriptures were sold, and one hundred and sixty-two were given away; and three thousand one hundred illustrated portions of the Scriptures were given away. There have been circulated through this medium, since March, 1834, three hundred and eleven thousand two hundred and seventy-eight Bibles, and one million five hundred and seven thousand eight hundred and one copies of the New Testament. They keep in stock almost four hundred sorts of Bibles, ranging in price from twelve cents each to more than six dollars a copy. Another object of the Institution is to aid in missionary efforts. "During the past year one hundred and eighty laborers in the Word and doctrine in various parts of the world have been assisted." The fourth object is to circulate such publications as may be of benefit both to believers and unbelievers. In a single year one million six hundred and eleven thousand two hundred and sixty-six books and tracts were distributed gratuitously. The fifth object is to board, clothe, and scientifically educate destitute orphans. Mr. Muller belonged to that class of religious people who call themselves Brethren, and are called by others "Plymouth Brethren."
