ERRATA AND ADDENDA.

Page [43], line 10, instead of northward, read eastward. [109]

line 17, instead of southward, read westward.

Page [53]. Observations in addition to line 20:—Wind blowing from the east produces these effects to a greater extent than from the north-east, and wind blowing from the south-east causes the sand on the sea-shore to be extremely loose and porous, while the north wind renders the sand firm, solid, and compact.

Page [68], line 18, read two hundred and ten, instead of one hundred and sixty.

Page [71], line 15, read from the north-west to the south-east.
