means the physical properties of the metal are changed, 
and the occluded hydrogen is regarded as existing in a 
solid form as a quasi-metal, called hydrdgenium, the spe- 
cific heat, specific gravity, and electrical conductivity of 
which have been approximately determined. Probably 
a part of the gas forms also a definite chemical com- 
eumscribing the foramen magnum, and to- 
gether constituting the first or occipital seg- 
ment of the skull. These several elements commonly 
coalesce; but the basioccipital may be represented only 
by cartilage, as in a batrachian ; or some of the elements 
may unite with otic elements and not with other occip- 
ital elements ; or several of the elements may unite 
with one another and also with sphenoid, parietal, and 
temporal elements. The occipital bears two condyles for 
articulation with the atlas in all mammals; one in all 
Sauropsida (birds and reptiles); one (or, if two, as in a 
batrachian, with no ossified basioccipital) in Ichthyopsida.

Professor Graham has shown its [palladium's] remark- 
able power of absorbing hydrogen. When a strip of pal- 
ladium is made the negative electrode in an apparatus for 
decomposing water, it absorbs 800 or 900 times its volume 
of hydrogen, expanding perceptibly during the absorption. 
This occluded gas is again given off when the substance, 
which Professor Graham believed to be an actual alloy of 
palladium and hydrogen, is heated to redness. Madan.
