Mar. 6. — Mr Campbell read an eloquent and interesting 
memoir on the scale of Being ; a report of which will appear 
in an early number. 
Mar. 20. — The Secretary read a communication from Dr 
Brewster, “ On the Connection between the Primitive Forms of 
Crystals and the number of their Axes of Double Befraction.’’ 
Dr Brewster finds that all crystals with one axis arrange them- 
selves under a certain series of primitive forms, and that those 
with two axes arrange themselves under another series ; while 
the remaining primitive forms are occupied by those crystals 
whose doubly refracting forces are in equilibrio by the combin- 
ed action of three equal rectangular axes.. It is a curious 
and important result of these experiments, that they nearly 
harmonize with the profound views in crystallography proposed 
by the celebrated Professor Mohs. 
Ayril S. — The Secretary read a communication from Captain 
Scoresby, On the best means of overcoming the obstacles to 
Discoveries in the Arctic Regions. Recourse must be had, he 
thinks, to overland journey s^ made in the early part of the sea- 
son, and in the mornings and evenings while the snow is firm. 
Small vessels of 100 tons burden, but not exceeding 150 tons, 
might sail to the northern part of Baffin’s Bay, with the view of 
wintering there. If the ships were to carry out with them Mor- 
ton’s apparatus for drawing ships on shore, (a machine which is 
now in use in the upper part of Leith harbour), and provided 
a sloping beach could be found, the vessels could easily be pla- 
ced beyond the reach of tide or ice, so as to form a tolerably 
comfortable winter habitation. We do not enlarge on this sub- 
ject, however, as we have reason to believe that Captain Scores- 
by’s views will be fully stated in the work on Greenland which 
he has now in the press. 
April lO.^Dr Hibbert finished his geognostical description 
of Shetland. 
During the course of his investigation, which continued for 
five months. Dr Hibbert met with several intei'esting simple 
minerals imbedded in the primitive and secondary rocks. These 
he particularly described when pointing out the character of the
