it must in like manner be admitted, that all the crystalline and 
arenaceous roehs which constitute the crust f the globe (I might 
say all the crystalline rocks which enter into the composition of 
the crust of the globe, and even the trachytic and basaltic rocks) 
are also formed by fire (I might say by water). The fabric of 
the science will then be overturned, and the science itself ren- 
dered subordinate to a favourite system, while error will thus 
occupy the place of truth. 
In the present state of science, and without entertaining any 
prospective views, it is extremely obvious that the probabilities 
are much in favour of the hypothesis of an aqueous (I might 
say igneous) formation. It would tend to diminish, instead of 
advancing, science ; and return it to its infancy, to admit any 
other opinion, so long as new facts could not be thrown into the 
balance of probabilities. 
The whole of this conclusion applies equally, and a fortiori^ 
to the amygdaloids of the grey-waeke, as well as to the green- 
stones and the porphyries which accompany them.

Ilundsberg, April 24. — The laying out of the beautiful 
plants that we last brought home employed us during the 
whole of yesterday ; and, as it also emptied our botanizing 
boxes, so we determined to replenish these with an abundant 
stock of Mercurialis ovata^ for our collection. Accordingly, 
we hastened this morning direct to Contobello, and pursued 
the buona strada” without much delay, though, as we went, 
we observed in flower the hairy Lotus corniculatus^ and Car ex 
distans, also C. glauca o£ Scopoli, and C. pracox of Jacquin. 
We likewise found a singular plant, whose name we cannot 
at present determine. It is an Apargia. Probably Scopoli 
has included this species under his A. hispida or Jmia ; but it
