98 APPENDIX. 



From these two instruments, which are well within the constructive power of any 

 native carpenter, results of very great value in the present state of seismology can be 

 obtained, though there are doubtless many more perfect instruments than these; yet 

 from their very perfection they are necessarily so expensive as to put them practically 

 beyond the reach of private observers, while the expenditure is not one that could be 

 recommended to Government ; besides, while these instruments, to develope to the 

 full their capacities, must be situated either at or in electrical connection with some astro- 

 nomical observatory where the results would be automatically recorded on a chronograph, 

 there is no astronomical observatory in India advantageously situated for seismolo- 

 gical observations. It is otherwise with tho two instruments above described, they 

 would be inexpensive and could be attended to by any one able to read meteorological 

 instruments. 



The day may not yet be far off when every meteorological observatory throughout 

 the earthquake-shaken districts of India may have attached to it these two instru- 

 ments or some more perfect form of seismometer ; and it is not too much to say that 

 when such is the case, and these observations are communicated to a single centre, there 

 to be compared and developed, five years will see more done towards learning the true 

 cause of origin of earthquakes than has been effected by all the speculative theorizing 

 of the past.
