Mr. Shaw, the inventor of new railway brake, wnio5
he expects will ultimately be adopted BY the direcsom
OF oil railways In the world" convened meeane N
other day. In London for the purpose Of making publs
the principles Of his invention Mr.. Hammond having
taken the chair. the inventor, Mr. Shaw, proceeded
explain his invention The great objection he said TO the
existing brakes was that shey were not provided VIII
means for aong on all the wheels Of railway train IS
once Newas invention had met this defect far a
short trains concerned but his. Mr. shaws pei
posed stop trains Of all lengths and within tho shcf
EFT distance He proposed to give tho power OF STOPPING
10 the engine driver without any assistance from brakes
eu and to give the power Of stopping within ono hua,
dred and ny yards whereas the present brakes did moi
hiring the trains up under four hundred and Hfy yarlR
The idea OF tho inventor appeared 70 bs to apply the
tarding power exercised by the dywhsel, or fam In
clock OF musical box 70 tho gradual stoppage Of ras
way train He proposes TO place fans under the carriage
and inside the wheels these fans 70 be connected By The
buffer rods which in turn are TO DO commanded ~ me
engine driver Nj, Shaw considers that the stmos-
hsrc pressurs exercised by the fans will be much more
eieotua than the existing block brakea The meeting
was rather thiny attended, but much interest was OK

At the last sitting Of the French Academy OF Sciences
n Leon soubeiran sent in paper on the rearing q
crabs and Holsters appears that these crustaoea co-
plets their growth the course OF six or seven year,
The lobster casts or Its shell 0ftener than the crab ana
this explains why its size Is much more considerable
for a. they grow these creatures find their aror ~
small 10 contain them the oftener. therefore, they
cast it, the greater is their capabiliy Of expansion.

corning the preservation Of wines BE stated In biz
paper that in Italy good olive oil is USED TO preserve
wine, not only in TASKS, but also in casks When ths
