Tlie re~iewer heartily ,joir~s his critic in his desire for a 'closer exaxnillation ' to deteriniile the jnstice of the commex~ts iiiade.

Tlie points under disc~~ssion nsu-are such as are not ally co~~siilcred ill boolis with wllicll the teacher is liliely to be familiar; mid erroneous arid confusing statements will generally be accepted, althougll not ux~derstood. The result must be dishearteiiiiig, if not disnstrous. I t seems ~viser, therefore, to war11 liixn to be on tile Iooliont for errors which have not been eliminated fro111 this first editiox~, but ~~-1lich arc, not liliely to be fon~ld in a second.

My residelice is close to Ascension cli~lrch, on the highest lantl anray fro111 tile boundaries of the city: the gratle is iiinot,y-two feet above mean level of the river, aiid two feet higher tlian the base of the capitol. I was in the thircl-story back room, facing east into the bacli-yal.d, and soutll into an alley. l'he house is of bricli, and above the 121iddl(, of tlie second story is isolated. The ~l~o c l i was a distinct axid very heavy and sudden jar, not accompanied by noise, u~iless by a slight rattling of tile wiiido~vs, and lasted less than a second. The sensation mas as if a very heavy body had strrlclc the earth, yet alst) as if the jar were partly upward rather than d o~n w a r d . Tllere was no secoi~d sl~ocli within fifteen minutes, altliongll I saw a paragraph in the daily press to tile effect that one individual alleges that lie felt a second shocli about 11 p.31. at Alexandria, Va.
