304 REPORTS ON THE STATE OF SCIENCE, ETC. 



May lid. 8h. In the Summary tlie longitude of epicentre is erroneously given 

 as 116-5° E. 



June 29d. lOh. Alternatives with focal depth +0-060 and epicentre either 

 30-6° N. 144-0° E. or 27-3° N. 138-5° E. are suggested ; but the material is scanty. 



July22d. 12h. Possible alternative epicentre (assuming errors of Im. at Athens 

 and 4m. at Budapest), 40-5° N., 25-5° E. (as on 1918 April 17d.). 



Aug. 8d. 12h. Focal depth +0-025. 



Aug. 12d. 5h. Possible alternative supposition of two shocks at 6h. 3m. 24s. 

 and 6h. 10m. 13s. from epicentre 35-0° N. 143-0° E. (as on 1922 March 16d.), recorded 

 by Osaka as separate phases of a more distant disturbance. 



Aug. 31d. llh. The previous occurrence is erroneously given in the Summary 

 as on 1919 Jan. Id. 



Sept. Id. 2h. The first of the disastrous shocks which destroyed Tokio and 

 Yokohama. 



Sept. 2d. 2h., 2d. 9h. 26m., 2d. 13h. 9m., 2d. 14h. 16m. Focal depth +0-010. 



Sept. 9d. 4h. Alternative solution, 9d. 4h. 18m. lOs. from epicentre 7-5° N. 

 79-0° W. (as on 1922 Mav 22d.), or perhaps two shocks as follows : — 

 9d. 4h. 16m. 25s.'from epicentre 0-0° 75-0° W. 

 9d. 17h. 11m. Os. from epicentre 35-0° N. 139-5° E. 



Oct. 15d. 7h. Suggested revised solution with focal depth +0-020 below norma] : 



Oct. 15d. 7h. .32m. 18s. | g i^.j^^re 8-0° S. 123-5° E. 

 15d. 7h. 58m. 25s. ( ^ 

 on the assumption that Batavia and Malabar are Im. in error. 

 Nov. 3d. 8h. Focal depth +0-010. 

 Nov. 17d. 2h. Focal depth +0-020. 

 Dec. 19d. 19h. Focal depth +0-010. 

 Dec. 28d. 22h. Focal depth +0010. 



Notes to 1924. 



Jan. 16d. 21h. Focal depth +0-030. 



Feb. 24d. 16h. Focal depth +0-030. 



Mar. 5d. 4h. Focal depth +0-030. 



Mar. 25d. 21h. Focal depth +0-060. 



April 3d. 2h. Focal depth +0050. 



April 13d. 13h. Focal depth +0-015. 



May 4d. 16h. Focal depth +0-060. 



May 14d.-16d. It is curious that four shocks from widely different epicentres 

 should be repeated from 1923 Oct. 7-17. 



May 25d. 13h. Focal depth +0070. 



May 28d. 9h. Focal depth +0-060. 



June 22d. 16h. Focal depth +0-020. 



June 30d. loh. Focal depth +0020. 



July 3d. 4h. The corrections to S near A=35° are small (in other cases they are 

 large). 



Jalv22d. 4h. Focal depth +0040. 



Sept. lOd. 5h. Focal depth +0-040. 



Oct. 8d. 20h. Focal depth +0010. 



Oct. 13d. 16h. Focal depth +0030. 



Dec. 26d. 23h. The disentanglement of these three shocks is, of course, subject 

 to much uncertainty. 



Dec. 27d. llh. Focal depth +0-010.
