Nicolaiew (Professor Kortazzi, details communicated by Dr. E. von 

 Rebeur-Paschwitz), 46° 58' 51" N., 31° 58' 28" E. From April 20 the hori- 

 zontal pendulum was constantly disturbed by the Greek earthquakes. 

 Strong disturbances occurred at the following times : — April 20, 

 5h. 42m. P.M. ; April 21, 4h. 18m. a.m., 8h. 12m. p.m. ; April 22, lOh. 32m. 

 A.M. ; April 24, 2h. 47m. a.m. ; April 25, Oh. 41m. a.m. ; April 27, 7h. 49m. 

 P.M. (very strong) ; April 30, 4h. 24m. a.m. ; May 1, Oh. 55m. a.m. 



Charkoio (Professor G. Lewitzky), 50° 0' 10" N., 36° 13' 40" E. From 

 April 20, 5h. 23m. p.m. to April 22, 3h. 5m. a.m., the horizontal pendulum 

 was disturbed ; April 20, 5h. 25m. p.m., beginning of the strongest move- 

 ments ; April 21, 4h. 21m. a.m., maximum of a shock ; 8h. 13m. p.m., be- 

 ginning of a strong movement ; April 27, 7h. 48m. p.m., beginning of the 

 movement. The disturbed state of the pendulum, with a few weak shocks, 

 lasted until April 28, 8h. 23m. a.m. 



Potsdam (Dr. Eschenhagen), 52° 22'55" N., 13° 3' 59" E. The magnetic
