The following letter was read — 



From Mr. E. H. Steel to W. T. Blanford, Esq., dated Revenue 

 Survey (temp, Suddia (Assam), April llth, 1870. 



1 Knowing the interest you take in such matters, I send you a 

 few notes of an earthquake felt here to-day. If it has been felt 

 with violence in Calcutta and neighbourhood, which I doubt 

 from the direction of the wave, it may be of interest to learn that it 

 extended as far as here, especially as I have the exact time, taken by 

 observation of the time on purpose. Our Longitude is nearly 96°, our 

 Latitude 27° 52 '; Calcutta Longitude is 88° 25 ', Latitude 22° 33 f ] 

 The difference of time will be about 32 minutes or less; this I 

 have not subtracted from the times in the following record. I regret 

 that I had no barometer the time, as we had a rare wind, easterly, 

 the direction from which the wave came, and which rose suddenly 

 after the shocks, died away soon after, and then was renewed for 

 four hours again. 



April, llth. 10. 49 a. m., three moderate shocks rapidly succeed- 

 ing one another, 2 sec. interval about. 



10.51. Got up a 6 in. Theodolite. Lower level E. and W., upper 

 N. and S. Direction of wave from E. to W., plainly evident. Con- 

 tinued wave motion, every 3 or 4 sec, until 



10.59, when it became slighter and oscillation slower. 



11.04. Still slighter and slower. 



11.09. Scarcely perceptible and ceased. 



Wind at first moderate and easterly, rose rapidly. Due east. 



Weather fine, a few clouds. Sunny. 



Thermo. 75°, at 11 a. m. 



12 a. m., wind moderated a little, though it afterwards increased 

 a good dual and died away at sunset.
