Small-Pox. 
contains rése coloured mica, garnet, and beryls, similar 
to those in your possession. With the assistance of a com- 
petent person, I blasted the rock yesterday, and sbiaied 
some fine specimens of the green tourmaline and very good 
sized beryls, one four inches in diaineter, and six inches in 
ength. The rubellite and rose coloured mica were not as 
abundant as I could bave wished. 1 procured, however, all 
that was visible in the two veins, which I discovered, and 
from the great abundance of granite in = vicinity, which 
is frequently traversed by veins of quartz aad feldspar, exhibit- 
ing the green tourmaline and beryls, lam confident more 
will be found. 
9. Small-Pox.—Dr. F. Pascalis, in an essay read before 
the County Medical Society of New-York, April 11, 1825, 
maintains that the virus of small-pox “is a compound and 
morbid formation from human «ffluvia”—that it “is an ani- 
mal poison, exclusively proceeding from human beings, and 
that when prevailing as an svidetaies it is of a recent aud fresh 
formation” ” ‘ene in car 
ce it appears is formed or aggravated by r dele~ 
effluv viii, which passing from pee to man, from 
biewth to breath, ‘gradualiy acquires its elementary intensity, 
by which a single particle or atom of it, similar to Jeaven, ex- 
cites a general ferment of the whole lymph of the human fab- 
ric.” ‘The variolus fomes can exist, Dr. P. thinks, under dif- 
ferent ~~ modified forms, such as chicken-pow, swine-por, 
ave — paces by the generic name of vari- 
cella. Dr. P. rds the commonly received opinion, 
‘that the small- so is pe sisieally unique and sui generts ;” 
and holds that there is an important distinction between epi- 
demic small-pox, and artificial or inoculated small-pox. 
Vaccination, he thinks is.a complete preservative against arit- 
Jicial small-pox ; but neither the vaccine disease, nor the 
inoculated small-pox i is a —— preservative against the 
epidemic disease.
