NJ. GnnuAuT proved in recent expert
ments that the quantity Of carbonic acid
exhaled by any ono individual Of an

CoNsIpERABLE changes IN the water
level Of several lakes in California and
Oregon are reported. II il stated that
Goose Lake, thirty miles long, was
nearly dry iii 1858 and 1854, but con-
tanned ten feet Of water in 1870, and itai
| depth has since been increasing. Clear
| Lake is also ton feet deeper than in 1854,
while Tulie Lake, in the same region, is
now ten or fifteen feet higher than then.
THouGnthe inycntionof tho barometer

shows the powder to be the fine pollen
Of species Of pine tree. The pollen

often carried by gales Thousand niles

FoR preserving the natural colors oi
dried flowers and plants, this process
has been recommended by German
scientists: Dissolve one part Of salicylit
acid in 600 parts Of alcohol, heat the
solution to boiling in shallow dish, anC
draw the plant through ii slowly; shake
off any excess Of liquid, dry between
blotting paper, and press in the usua
manner. Natural colors are said 10 bI
thus preserved in greater perfection thar
by other processes.
IT IS believed that porosity is prop

formed some years ago, to ascertain
whether water could be compressed, re
suited in proving that gold is porous

which the liquid was driven could nc
have been more than the two-milliont
