116 Protection of Persons from Fire. 
' The cloth of amianthus or prepared wool will alone afford a sufli- 
cient guard in common cases; while the metallic gauze in extinguish- 
ing flame does not sufficiently intercept the heat. The latter also, by 
its rigidity, constrains the motions of the firemen, a serious inconven- 
ience when we consider how essential it is for them to enjoy the full 
play of their limbs. ‘The reporter therefore infers that woollen gar- 
ments, sufficiently thick and close, and well impregnated with saline 
solutions, or preferably perhaps several lighter folds, one over another, 
of close stuff, to prevent the admission of air, would alone be sufii- 
cient, and that at farthest it would only be necessary, in particular 
circumstances, to add moveable pieces of metallic cloth, to guard 
those parts of the body which are the most exposed to the heat, pre- 
serving always the two coverings ata certain distance from each 
other ; for a close contact renders the metallic tissue more injurious 
than useful. 
The reporters speak highly of the use of the buckler, either with 
or without the dress of prepared stuffs—and also of the advantage of 
metallic grating or wire work, as a stoppage to flame in doors, wit- 
dows, &c. 
On the whole, they recommend im strong terms the means invent- 
ed by the Chev. Aldini, to enable firemen to penetrate buildings 00 
fire, to remove valuable materials, and to preserve the lives of those 
who are liable to perish in the most frightful torments. 
The third report in the appendix is from a commission appointed 
by the Prerecr or Pouice, consisting of D’Arcet, Marc, Baron 
de Plazanet, Meyniel and Gualtier de Claubry. The third named 
commissioner, Baron de Plazanet, colonel of the fire companies of 
Paris, devoted much attention to the experiments of M. Aldini. 
The report speaks favorably of the lamp or lantern of metallie 
tissue, introduced by the author. It may be set down upon straw 
or hay, or be surrounded by it without danger. If a straw should 
penetrate the lantern and take fire within, it will not communicate 
the flame beyond the meshes. A moveable muff has been added, t? 
guard the flame against a current of wind. 
It would have been desirable in the opinion of the reporters, that 
an experiment had been made in a close room or building filled with 
fire and smoke, and they are not confident that without a reservoir 
condensed air, or some additional artificial way, there would be any 
safety in remaining in such a situation.
