Ihave since found in a marble of the same kind but from a dif- 
ferent quarry, and a few miles distant from the first, a quartz 
almost as fetid as the necronite, and likewise associated with 
small prisms of titanium. : 
“These substances carry with them a degree of interest in 
another point of view. They seem to invalidate the opinion . 
that the fetid smell of secondary limestone, slate, &c. is deri- 
ved from the decomposition of animal matter; as their gangue 
is decidedly a rock of primitive formation.” 
Another new mineral observed by Dr. Hayden. 
“Exclusive of the interest which the necronite has excited 
with me and several others, I have besides stambled upon anoth- 
er substance, if possible stilt more interesting. I discovered it 
_ in an imperfectstate, about 4 years since, but not until recently 
have I been able to find it perfect, in beautiful garnet colored 
cubic crystals 1 of an inch square or nearly. ‘These crystals 
are very liable or subject to decomposition, in which state they 
Present a perfect but spongy cube. Although they resemble the 
cubic zeolite, yet they have nothing of its character with them 
besides,” 
: Remark. 
Dr. Hayden without doubt alludes to the chabasie, of the Ab- 
bé Haiiy, formerly but inaccurately called the cubic zeolite ; 
for it is really a rhomboid very nearly approaching a cube—its 
angles being 93° 48’, and 86° 12’. ‘

The author declines describing the methods of embalming 
Commonly employed, and proceeds to describe the mode which 
Was for the first time employed by Dr. Chaussier. : 
©This process consists in placing the dead body thoroughly 
emptied and washed, in water kept constantly saturated with 
Corrosive sublimate. This salt gradually combines with the 
lesh, gives it firmness, and renders it imputrescible, and inca 
Pable of being attacked by ‘insects and worms.
