270 Memoir on Indian Earthquakes. [No. 136. 



unhealthy appearance so common among them. The temperature of 

 the spring in January last, (1829,) was 103° ; but it varies, for in July, 

 1826, I observed it as high as 110°. The flow of water also varies 

 considerably." 



Dr. Malcomson of Bombay, having made enquiries of Dr. Falconer, 

 late Superintendent of the Botanic Garden, Seharanpore, as to whether 

 this spring was affected by the Earthquake of the 19th February, the 

 latter referred the question to me, and I availed myself of the assistance 

 of my intelligent and indefatigable correspondent, Mr. Bingham, in 

 instituting enquiries on the spot. Mr. Bingham applied first to the 

 Deputy Collector of the district of Goorgaon, in which district the 

 spring is situated, but so little interest was taken by him in the matter, 

 that he did not even reply to Mr. Bingham's letter. This indifference, 

 on the part of the Deputy Collector, was, however, compensated for by 

 the interest and activity, shewn by Mr. H. Martin, the Superintendent 

 of Roads in the same district, who so soon as applied to by Mr. 

 Bingham, visited the spring, and addressed the following interesting 

 letter to me, giving the results of his enquiries : — 

 Letter from Mr. H. Martin to my address, dated 1 5th October, 1842.

 which I trust will prove of utility to the object you have in view. 



" On the 19th February last, (the day of the Earthquake,) the water 

 in the wells became as cold as that of the ordinary wells of this country 

 — the issue of the spring was observed to flow much slower, and in less 

 quantities than formerly, and at times the spring would be completely 

 dry. No disturbance of any kind was visible, nor any other change 

 than what I have noticed. The abo^ve appearances continued for twenty- 

 five days, when the wells resumed their former state. 



" I would remark, that this statement may be credited, as all to 

 whom I applied answered with readiness, and from the length of time 

 which the appearances lasted, there could hardly be a mistake. 



" Should you wish for any more detailed particulars, or if I could be 

 of any assistance to you in any way on any other subject that may
