Mutton, beef, and sheep's kidney showed no lithium : one kidney had 

 a slight trace. 



CONCLUSIONS. 



1. On the Rate of Passage of Solutions of Lithium into the Textures of 



Animals. 



Chloride of lithium taken into the stomach in quantities varying from 

 one quarter of a grain to three grains, will pass into all the vascular parts of 

 the body, and even into the non-vascular textures, in from one quarter of 

 an hour to five hours and a half. 



2. On the Rate of Passage out of the Textures of Animals. 

 Chloride of lithium passes out by the skin as well as by the urine ; and thus 

 the animals can redose themselves with chloride of lithium from the hair 

 and feet, and prevent accurate observations. Hence probably chloride of 

 lithium, in quantities varying from half a grain to three grains, will continue 

 to pass out of the body for thirty-seven, thirty-eight, or thirty-nine days ; 

 and even after thirty-three days, traces may be found in the lens ; but 

 in three or four days no lithium may be detectable in the non-vascular 

 textures. 



3. In man, carbonate of lithia, when taken in five- or ten-grain doses, may 

 appear in the urine in five to ten minutes if the stomach is empty, or 

 twenty minutes if the stomach is full, and may continue to pass out for six, 

 seven, or eight days. 



In two hours and a half, traces may be in the crystalline lens, and in 

 five or seven hours it may be present in every particle of the lens and 

 in the cartilages. In thirty-six hours it may be very evident in the 

 cartilages. And in seven days not the slightest trace may be detectable in 

 the crystalline lens. 



4. Though in the solid and liquid food infinitesimal quantities of lithium 

 may enter the body, usually no proof of their presence in the organs or 

 secretions can be obtained. 



IV. "Lunar Influence on Temperature." By J. PARK HARRISON, Esq., 

 M.A. Communicated by the Rev. R. MAIN, F.R.S. Received 

 April 27, 1865. 



The tabulation of an unbroken series of thermometric observations for the 

 several days of the lunation during fifty years having been completed up 

 to November 1864, and an amount of lunar action detected which appears 

 sufficient to set at rest the long vexed question of the moon's influence 

 over our atmosphere, I venture to think that the time has arrived when 

 it becomes a duty to lay the results of the investigation before the Royal 

 Society.
