(8) Annular Eclipse of December 25, 1954. 
This annular eclipse crosses the Colony from Hondeklip Bay to 
Algoa Bay. The central shadow enters the Colony at Hondeklip Bay 
at 5 h. 55 m., morning (G.M.T.), passes eight miles to the north of 
Calvinia, seven miles to the south of Fraserburg, four miles to the 
north of Beaufort West, and finally passes off the Colony at Bird 
Island at 6 h. 6 m., taking eleven minutes to cross the Colony. 
The breadth of the zone of annular eclipse is 180 miles ; that is, 
within ninety miles on either side of the central line the sun will be 
annularly eclipsed. Beyond this zone the eclipse will be partial, and 
will be well seen all over the Colony. 
Along the central line the duration of annular eclipse will be six 
minutes on an average. 
The further any place is from this central line, the shorter will be 
duration of central eclipse. 
The following places lie within the zone of annular eclipse :

(9) Annular Eclipse of January 25, 1963. 
This annular eclipse crosses South Africa from Danger Point to St. 
Lucia Lake. The breadth of the zone of annular eclipse is only twenty- 
eight miles; the eclipse is therefore just on the border of totality. 
Indeed, so narrow will the ring of light round the mocn’s disc be, 
that it is probable it will be quite, or nearly, invisible to the naked eye. 
The eclipse is therefore practically total. 
Points within the central zone are:
