The fuel Of the ancient Romans Arch
clusiVely Charcoal This was burned in
open pans without crate or f1ue, and gave
economical heat for living rooms and

such fires yield no considerable amount
of carbonic oxide. The Inconvenience OF
chimneys were avoided. the heat could be
easily regulated, and pan with burn
ing surface of 1888 meters has Suft1ced
to heat church seating 1000 people.
Certain kinds Of coal deteriorate rapid

ford has expressed the belief that the to-

under water is the remedy of an English
experimenter who, noting the fine quality
Of coal dredged from a harbor, has Kept
Monmouthshire steam coal under sea wa
ter two months with a loss of less than
1 per cent in heating power.

curious biological investigation be-
gun by Prof. G. H. Nuttall, opens up a
wide field of astonishing possibilities. He
has discovered that when human blood
is injected into the rabbit or other ami
NAL, the serum Of the latter becomes an
"anti-serum'' for human blood, this anti
serum giving a precfp1tate When added
to the serum of human blood. but not with
any other serum except that of certain
apes. In the same way ant1-SerumS have
been made for the blood of horses pigs,
dogs, etc. The value of these substances
as tests is lessened by the fact that Wig
orous ti-serums-especially that OF the
pig-react after sufficient time with the
blood of apes, bears. men, dogs, rats. bats;
etc, but instead of proving affinities Of
the pig with all the mammalia this is held
to show that besides the specific anti-se-
rum, there is a generalized ia anta-serumss
mammal gives a reaction with non
mammalian blood. Anti chicken and an
ti-ostrich serum act more or less on the
blood OF all fowls, anti-egg serum gives
results suggesting kinship between birds
and reptiles, anti-allgator serum affects
only alligator and turtle blood, anti-lob-
ster serum reacts only with the blood OF
Holsters and crabs, and anti-frog serum
acts only on the blood of frogs.
