pressure and the ebullition are all simultaneously accelerated, since 
these results are reciprocally dependent on each other. 2 
The advantage of this apparatus and method of operating, Se 
first in the certainty and facility with which the apparatus is secured 
against the access of the atmosphere ; and in the next place, in the 
index of the diminishing resistance, afforded by the rise of the mer- 
curial column. 
Arr. VIIL—Notice of Oriental Minerals.

1. By Prof. F. Haut. 
A number of years ago, I received a box of minerals which were 
collected in Greece and the neighboring countries. For the collec- 
tion and transmission of them I am indebted to my worthy friend, 
the late Rev. Pliny Fisk, American missionary to Palestine, who 
died at Beyroot, in Syria. The specimens were sent without 
names, but were all carefully numbered, and notice given, in most 
cases, of the places from which they were taken. The following 
remarks on them were prepared shortly after they came to hand, 
but, in the hurry of business, the paper was thrown aside, and never 
again came under my inspection, till a few days since. Thinking 
that the publication of it was due to the memory of the excellent 
donor, 1 take the liberty, sir, at this late period, to ere it at eae 
disposal. 
From Sardis. 
1. Milky quartz. A fine specimen—its aspect is slightly greasy. 
2. “From the ruins of a church at Sardis.”’ Calcareous breccia, 
composed of white angular fragments of carbonate of lime, held 
together by a calcareo-argillaceous cement. 
3. Yellow —— or citrine, picked up ‘ between Sardis and 
Philadelphia.” 
4. White granular marble—very beautiful, “ from the palace in 
Sardis.” 
5. Grayish colored, disintegrating carbonate of lime, “ from the 
market.” 
6. “From the walls of an ancient church.” Marble sucré, an 
elegant specimen.
