OSMIUM. -

The peroxide (05 04), commonly called osmic acid,

is produced when the metal is heated strongly in air or oxygen,

and forms colourless acicular crystals freely soluble in water,

and very volatile. At about 1000. this compound gives off an

extremly irritating and irrespirable vapor, and hence the name

of the metal, from the Greek word osme, odour, It produces &

permanent black stain upon the skin, and at the same time causes

an erruption which is difficult to heal. It violently attacks

ail mucous membranes, and its vapor may cause partial or total

ix

blindness by depositing a film of metallic osmium on the eyes.

A solution of the peroxide is employed in histological work

for staining fat and nerve substances.
