Profesor Rntlolf t !b of Liepzic, the discoverer of the 'critical days," iu_ giving their nnmber, order ani dates for the coming yonr in the columns of The Dentsche Kai-erKalenderfor 1895. States that observations begnn in 1803 convinced him that the influouce of the attraction of the inoon and sun upon the waters of the sea had a similar effect upon the oeean of the earth's atmosphere as well as upon the liquid and volatile masses contained in the interior of our globe. Ho discovered that great atmospheric disturbances, shocks of earthquake and explosious in mines were surprisingly often coincident with the days upon vrhich the most exteusive tides and other oceanic commotious veere caused by the influcnce of either moon or sun, or both These periods Professor Falb distingniahes by the name of ' 'critical days, " because they mark on the one side pcriodical "turning points" in the equilibrium of the neptuilic, phnoinc and atmospheric masses above mentioned, and on the other sitie aSord tlie measure and nieans for computing the degree and effect of tunar and solar forces upon our planet The individual constellatious affecting each for itself an increase of these forees are: First, the perigee - that is, the tiniewheu moon and earth are nearest tp one another; secoud, the moon's equr.torial position; third, the perihelion, when our globe is nearest the sun; fonrth, the sun's equatorial position; fifth. the syzygies, or new moou and full moou; sixth, tho lunar or solar eclipses The coming year vrill be csppcia'ly notable l'or the fact of its three most critical daya being aecompanied by eclipses. In mentioning the dates iu their different orders and grades of individual elïectiveness Professor Falb tafces care to state that the resuits of the strongest attractious often precede their "critical days," as theoretically computed, by one or two days, while those of lesser import may be from two to three days larer than periodically fixed. The latter may also be the case at the time of critical days of the first order wheuever long continuing and extraiivo atmosphrric pressure or eastern winds prevailed previous to these dates. Phe following are the "critical days" or 1895: Of the first order, Sept. 18, March 11, Aug. 20, Feb. 9, Oct. 18, April 'J, July 22 and Jan, 11. Of the second order, May 9, Nov. 16, March 26, April 25, Deo. 81, Oct. 14, Feb. 21, Juno 22, Sept. 4 and Nov. 2. Of (he third order, May 24, Dec. 2, Dcc. lü, Tune 7, Aug. 5, Jan. 25 and July 7.
