Lett for ever be remembered, To their dis.
credit, and as preof that we are not to eN-
pect improvements exclusively from men OF
science, that the entire race OF modern che
mlSts opposed themselves TO the introduction
OF the gas OF coal and that Winsor, mocha-
mic, laboured III London fer years before he
could draw the attention OF few opuent per-
| sous to the principle. Now, however, they
| hnd that il is worth all their discoveries put
together for the last thirty years, and they are
| beginning to write about it, and make expert
men,s upon it. Tins NJ. Lampadius has pub.
! llshed a set of experiments OH the quantity OF

cubic feet OF gas, equal to the supply of rs 900
Argand Lamps, each giving the light OF six

| III. Theodore dc Saussuer has published the
result of a number of experiments 10 deter

| in the atmosphere dining summer and winter.
| His method Is to til large glass globe with

| quantity OF barytes water. The carbonic acid
| III tbs air was determined by the quantity of
| carbonate of barytes formed In winter 10000
| parts of air in volume gave mean ofl.79 parts
| ofcarbonc acdgas in 10, 600 measures ofair. In
| summer 10000 measures of air gave mean of

M. Majendie lately fed a dog upon sugar 81
distilled water. In about fortnight il became
lean; on the twenty-frst day an nicer appear

which gradually increased, penetrated the col

leauness continually increased, the animal lost
its strength, and died on the thirty-secOnd day.
| \ second and third dog, fed likewise upon
gar and water, shared a similar fate. Two dogs
ted upon Olire oil and water died on the thirty
| sixth day, with precisely the same phenOme-
| ua, except the liberation in the cornea. Seve-
| raj dogs were fed with gum and water: their
| fate was precisely the same. y dog fed ON hit
| ter died on the tbirty-siXth day, with precisely
| the same phenOmena.-Fr rom these experiments
| 1t is obvious, that none ofthese articles
