me, would not the electric telegraph be a capital means of transmit- 

 ting the intelligence of a thunder or hailstorm, or any change that 

 has taken place in any part of the kingdom where railways obtain, 

 and by that means unravel nature's secret with regard to meteoro- 

 logical phsenomena ? 



But as those stations should be provided with every requisite for 

 taking all the necessary observations, so as to form a compendious 

 series of meteorological remarks, you will ask who is to furnish the 

 means ? In answer to that I would say, could not the Royal Society 

 do that, and might not the British Association take the concern 

 under their fostering care ? You will also say, would not the atten- 

 tion necessary to be paid to these observations lead to inattention in 

 respect to the trains ? I hope not ; and I believe, before long, such 

 improvements will be made in railways as to make it nearly a phy- 

 sical impossibility for accidents to occur.
