In the Philosophical Magazine, vol. xx., Messrs. 

 A. and F. Dupre gave the spectrum analysis of 

 London waters. All the different waters examined 

 gave lithium. The shallow waters appear to be 

 richer in lithium than the deep-well waters. The 

 different waters examined were: Thames water at 

 high and low tide at Westminster Bridge ; the 

 water from Chelsea and Lambeth Water-Com- 

 panies; New Eiver water; Duck Island well, in 

 St. James's Park ; Pump in Lincoln's-Inn. These 

 were above the London clay.
