98 EEPORT— 1895. 



February 12-15 (0"-43, 0"-25, 0"-39).— E shows well-marked daily 

 curves. A out of order, and therefore no record. F found to have changed 

 its sensitiveness ; therefore reset, so that 1°=0"'23. From 12-13 F 

 wandered from 75-5 to 52 (8""97), and again from the 14-15 it crept from 

 72 to 62 (2''"30). These movements, which so often occur with F, mean a 

 change in sensibility. 



Both instruments show tremors of 3 mm. 



February 15-19 (0"-43, 0''-25, 0"-26).— On E and A the daily waves 

 are seen as a succession of symmetrical waves, gradually increasing in 

 height and in length. Close upon the crest of the last and largest of these 

 waves an eai'thquake occurs. F only shows the last of these daily waves, 

 the remainder of the trace being a straight line, indicating a slight N.E. 

 sinking (1"'30). Tremors on all three instruments are slight. 



February 19-22 (0"-43, 0"-25, 0"-25).— E and A show a continuation 

 of the daily waves. Between the 21st and 22nd both instruments gave a 

 straight line. F only shows the wave of 20-21, but it shows a N.E. sinking 

 from 76 to 40 (8"-00). 



On the 20th, at 9.30, there was a strong shock. A shows two series 

 of strong tremors, Avhich are only faintly indicated by the underground 

 instruments. 



February 22-26 (0"-43, 0"-25 0"-26).— E and A show well-defined 

 daily waves. F is nearly a straight line, but wandered about 30 mm., as if 

 N.E. had sunk. 



Tremors are seen from 6 a.m. until noon on the 23rd, and again from 

 6 P.M. on the 24th to 4 p.m. on the 25th : on A and F they reach about 



5 ram. 



The earthquake of the 24th is not shown. 



February '2&-March 1 (0"-43, 0''-25, 0"'26). 



The daily curves on E are marked, but they are irregular. The shock 

 of the 27th occurs just over the crown of the daily wave, which was at 

 10 P.M. The ci-est of this tilting, both in time and amplitude, was unusual. 



On A and F the daily curves are slight ; on A, like E, they are 

 irregular. 



Tremors of 2 or 3 mm. are shown on A and F on the 26th, 6 to 7 p.m.; 

 27th, 6 A. to 4 p. ; and on the 28th, 6 a. to 1 p. The last are visible 

 on E. 



F wanders by a N.E. sinking through 10 mm. On March 1 the 

 direction of motion commenced to change, that is, there was a N.E. lifting. 



March 1-5 (0"-43, 0"-25, 0"-26).— On E the daily curves are large, 

 but at unusual times. 



A shows slight daily curves, but a N.E. lifting of 10 mm. F shows a 

 N.E. lifting of 22 mm. 



Tremors are seen on A on the 2nd, 2 A. to 11 A. ; and this agrees with 

 E, but not with F, which shows slight tremors, March 1, from 9.30 a. to 

 midnight. 



March 5-8 (0"-43, 0"-25, 0"-25).— E shows a well-marked series of 

 daily curves, and wanders 8 mm., as if the S.E. was rising. The daily 

 curves on A are slight, but the trace is faint. F wanders 40 mm. as if 

 the N.E. was rising. 



On March 6 small tremors are recorded, but only on A. 



March 8-12 (0"-43, 0"-25, 0"-26).— E shows slight daily curves on 

 the 8th, 1 p. to 10 p. A sinks on N.E. side 4 mm., showing tremors of 



6 nmi. It then ri.ses to the 10th, 8.30 p. 12 mm. At 8.40 an earth- 

 quake.
