The books of reference used in the following lessons would make an extended list, and in some cases the volumes named could only be found in reference libraries, as they are now out of print; it would therefore be of no advantage to give a complete enumeration of them here. I have given copious and extended notes upon many subdivisions of the lessons, especially where the books quoted would be difficult to obtain. The following named works, however, can be obtained and some of them are indispensable: _The Seventy's Indispensable Library,_ consisting of the Bible, Book of Mormon, Doctrine and Covenants, Pearl of Great Price, Richards and Little Compendium--this set of books in special and uniform bindings can be obtained; and we suggest that it would be a good thing for prospective missionaries among the Seventies to get these books in convenient form and durable bindings, so that when going upon missions they can take books with them with which they are familiar through frequent handling and reading. _Some Standard Dictionary of the English Language,_ such as is used in high schools and academies, where unabridged Standard Dictionaries cannot be obtained. _A Dictionary of the Bible._ (Dr. Wm. Smith's "Dictionary of the Bible," the four-volume edition by Prof. H. B. Hackett, contains, it is said, "the fruit of the ripest biblical scholarship of England"). _Smith's Smaller Dictionary of the Bible_ (one volume) is the same work condensed. In somewhat the same line, owing to its very valuable introductory articles (thirty in number, one of which, "Belief in God," we were permitted by the publishers to reproduce in the January and February numbers of the Era) is _Dummelow's "One-Volume Bible Commentary,"_ published by the MacMillan Company, New York. Some _Standard Ecclesiastical_ or _Church History,_ such as Mosheim's or Dr. Neander's. The former can be had both in one or three volumes. The latter is in six volumes. In this line, and in preference to any other Church histories--after Mosheim's and Neander's--that have fallen under my notice, I recommend for the period it covers--the first ten centuries--Dr. Philip Smith's "History of the Christian Church," two volumes. The Ecclesiastical History of Eusebius Pamphilus, covering the first three and one half--nearly--Christian centuries; and the Early Christian Literature Primers, four books, covering the first seven and a half centuries. _The History of Christianity._ This is a collection from the writings of Gibbon, chiefly selected chapters from the author's celebrated "Decline and Fall of the Roman Empire," edited and annotated by Peter Eckler. It is published in one volume, and as a history of Christianity's struggle with Pagan philosophy, and of the paganization of Christianity in the Early Christian Centuries, it is a valuable work.
