elucidation of the mysteries of numbers, which, indeed, enter

so, and in so far as we do so, our quest can never prove either 
meaningless or barren of results. 
Quantum peat of electric discharge.—By D. N. Maik 
and A. B. D. 
On i e quantum i eory, the energy of a vibrating system is a quan- 
tity which depends only on the wave lengths of the rapt ogre

well as the minimum potential difference requi ired for a spark and this 
energy is also considered.

Earth-air current at Patna.—By V. H. Jackson and K. N.

Most of the measurements of the earth-air current a recorded 
have been made by eye observations only, which are necessarily limited 
in number. In consequence, very little is known Fr maa the diurnal
