Past eight o'clock! O Herrnhuth, do thou ponder: Eight souls in Noah's ark were living yonder. 'Tis nine o'clock: ye brethren, hear it striking; Keep hearts and houses clean, to our Saviour's liking. Now brethren, hear, the clock is ten and passing: None rest but such as wait for Christ embracing. Eleven is past! still at this hour of eleven, The Lord is calling us from earth to heaven. Ye, brethren, hear, the midnight clock is humming: At midnight our great Bridegroom will be coming. Past one o'clock! the day breaks out of darkness; Great morning star appear, and break our hardness! 'Tis two! on Jesus wait this silent season, Ye two so near related, Will and Reason. The clock is three! the blessed Three doth merit The best of praise, from body, soul, and spirit. 'Tis four o'clock, when three make supplication The Lord will be the fourth on that occasion. Five is the clock! five virgins were discarded, When five with wedding garments were rewarded. The clock is six, and I go off my station; Now, brethren, _watch yourselves for your salvation_. F. B. RELTON. _Horology_ (Vol. iv., p. 175.).--H. C. K. inquires for the best _scientific_ work on horology. In my searches after the history of time keeping in all ages, I found none more useful than a little tract, the production of a watchmaker, and to be had at 81. Fleet Street. The _Mirror_ of 1824 contains some interesting notes on this subject. C. R. Paternoster Row. _The Aneroid Barometer_ (Vol. iv., p. 295.).--The intended signification of this name, "aneroid," can of course be only determined by the person who conferred it; upon any less direct authority the derivation quoted from Mr. Dent's description can scarcely be received. The meaning of νηρὸς is _moist_, rather than _fluid_; but even admitting the latter signification, then the last syllable ought surely to be referred, not to εἰδος, but to its root εἰδω (scio); _perceivable without fluid_ being a much better characteristic than _a form without fluid_. But taking into consideration the peculiar construction of this sort of barometer, its flexible diaphragm supported from within against the pressure of the atmosphere, may not its name have been derived from ἀνὰ (adversus), ἀὴρ (aer), and οἶδος (tumor)?
