white flocky vpininiilen Carbonate of ammonia dissolves the earth 
most completely; the remainder, which is in very small quantity, ap- 
pears to exhibit other reactions. With sulphuric acid the earth gives 
salt which is soluble with difficulty and crystallizes easily. The most 
peculiar fact connected with the new earth is the behavior of the chlorid 
on heating. This gives a white sublimate which is precipitated by pot- 
ash, while a basic oxyd(?) remains. If this be moistened with chlor- 
hydric acid and heated, the sublimate is again formed. The earth —

obtained, meantime no name is proposed for the supposed new element,

y therefore not be amiss to show. that the principal period may 
bin Sotto r by my theory of terrestrial magnetism, which is 
upon only one single hypothesis, and which seems to account for all 
known phenomena of terrestrial magnetism. This hypothesis is that am 
electrical current is a current of ether—a hypothesis which is apparently 
the legitimate result of modern science, a from which I think the prin- 
cipal laws of static and dynamic electricity can be analytically deduced. 
From this hypothesis it follows that af aneaaly bodies, having both 
a a and rotatory motion, are magnets. (See my memo ir enti-
