358 Dr Tilesius on the Volcano of Cooslma, 
Fig. 3. In this view, the before-mentioned division of the 
summit again appears a little from one side. We here 
see also a fallen crater with white smoking margin, out 
of which blue sulphur flames ascend, filled in the middle 
with volcanic ashes ; and near to, and below which, ap- 
pear pointed basalt-shaped masses, and conical-shaped 
peaks, which appear as rf formed by the neighbourhood 
or action of the sea-water. The rock lies here, accord- 
ing to the before-taken observation, S. W. 50°. From 
this side the greatest number of spiraculae, and the deep- 
est cavities through which the sea- water can force itself, 
are visible. Here also are seen the brown-red porous and 
wave-shaped margins of the layers and beds of dark co- 
loured lava, lying upon one another, which seem to have 
been deposited in the shape of steps, and must have 
found their place at different times. This view was taken 
on the same day, at 10^ 37”^ A. M., when the objects 
were seen with peculiar distinctness. 
Fig. 4'. In this view, the associated summits of the moun- 
tain appear. The rock is seen in its greatest latitude ; 
according to the needle it lies S. W. 50° to 60°. First 
and nearest appear the two points of the mountain, which 
we saw in Fig. 1. ; then comes the crater, which we saw 
sidewise in Fig. 3., and below it, and very near to 
it, the conical summits of the basalt-shaped massfes, which 
apparently had been formed by the motion or approach 
of the lava, while in a liquid state, to the water of the 
sea, and of which there was a side view in Fig. 3., 
but which, from this view, appear to be the ruins of a 
fallen crater. We also discover inUhis view, by means 
of the wave-formed, brown-red, and weather-beaten mar- 
gins of the naked layers of lava, the former periodical 
flowings of the lava, which lies in masses, like layers, up- 
on one another, and seems to represent steps and stairs. 
This view of the mountain, according to which it lies in 
S. W. 50°, 60°, was taken an hour later, namely on the 
4th May at 11^ 7”^ A. M.
