The smoEeless boiler of Sir John Primrose
of GLASGOW, is claimed to be revolutionary il
several ways. It depends upon separat
waterjacketed chamber, in which combustion
takes place, and only the gaseous products o
combustion impinge on the fire or water-tub
steam-raising surfaces. The air and fuel ar
from the furnace while no smoke or carboni
acid comes from the chimney funnel Grea
economy in fuel and efficiency in steam ar
effected, and experiments on marin

The beer-poisoning epidemic of Manchester
Eng, has been the subject of a prolonged gov
eminent investigation. final report show
that there were 5000 cases of poisoning, witt
more than 100 known deaths, and that tn
arsenic was introduced into the beer by suga
or glucose that had been contaminated by tn
sulphuric acid used in its manufacture. Pois
oning in other localities has been traced to tn
contamination of malt by the use of arsenica
gas-coke in drying. Various foods are liable t
contain arsenic, including golden syrup ant
treacle, substances containing glucose variou
extracts of malt, prepared and infant food
and yeast cakes.
