Recently the dome Of st. Peters. in
Rome, was rcclad at an expense to the
Vatican Of $4,000. The old sheaihing re-
quired such continuous repairs that 1t was
deemed better to replace it. The sheets OF
lead which now cover the dome weigh
1CS,Cl0 pounds, and would extend over
more than an acre and hall OF land II
they were spread ont Nat.
IL il announced in the Nature that a
eroito from 10 10 metres high has been
discovered in 4 rock washed by the sea, in
the Mortiban. by NJ. Gmllard. lie has
since continued his researches at low wa
ter, and found some human bones, ancient
carthcnware marked with categorical
figures, aud coins believed TO have been
struck v the ancient Gauls.
Suppose said an examiner TO a stu
dent in engineering, "yOu had butt an en-
CINE yourself, performed every part OF the
work without assistance, and knew that It
was in complete order, but when put on
the road the pump would not draw water,
what would YOU dO!" IL should look
INTO the tank and ascertain il there was any
witor TO draw" replied the student.
Experiments indicate that the effect OF
| light upOn plant TISSUES without chlOr0-
rlyil. such as roots. rhizome, blanchcd
| nlants, and some parasitic plants. is TO de-
int ity Of no
carbonic acid being given of and oxygen
assorted In darkness than in hight. The
amount OF oxygen absorbed is, however, in
| tie same proportion to the carbonic acid
| giyCn or in light as in darkness.
Elastic rubber tubing, perfectly gas
| tight and free from smell, has l.tely been
| invented. |, is made OF two layers o! ruO-
| her. with pure soft 'in-ioil between them.
and it retains the ilexibility and elasticity
| OF a simple rubber tube. Ii ought TO be
| serviceablc as connection between q
| heating or Illuminating gas supply-pipe
and a Gas-burning apparatus which re-
| quires TO he movable, II this sort OF rubber
| and tin Tubing can be manufactured OF
sufficient length.
In the course OF his Cantor lectures on
| alloys used Tor coinage Mr.. Chandler Rob-
erts chemist of the British Mint, said that
short cylinder was the geometrical form
which. next TO the sphere, presented the
smallest surface for the greatest weight,
and, consequently, in order 10 reduce the
wear OF coins TO a minimum, their thick
ness should be equal to their diameter.
Such form would present many incon-
vemencies; but on the other hand, coins
should not be made too thin, aud much
may DO gained by even small approach TO
theoretical requirements.
