These Observations were published in Russian in 1904, the fruit of research by the Russian Orthodox Church into the suitableness of the American Book of Common Prayer for use in an American congregation that had converted to Orthodoxy. The editor does not consider them to be pro or con regarding the content of the Prayer Book, but whether or not the Prayer Book adequately expresses the Orthodox faith.
The review by Bishop Tikhon concludes that in several essential aspects the American Prayer Book is inadequate as a liturgical resource for an Orthodox congregation.
The answers were composed by Bishop Tikhon (1865-1925), from 1898 to 1907 the Russian Orthodox Bishop, first of the Aleutian Islands and Alaska, later of North America. He returned to Russia in 1907 and was raised to the dignity of Metropolitan of Moscow, and in 1917 Metropolitan of Moscow and All Russia.
