Proceedings of the South African Philosophical Society. xvii 
certain puzzling figures which have not been recorded from other 
localities. One of these consists of a rude slipper-like form with 
seven bars across it; another is a circle with seven peripheral 
radiating bars, and a third shows three concentric circles, from the 
outer of which there extend twenty-one bars. Mr. Schwarz thought 
that the first-mentioned figure might be a tally. 
Mr. McEwen suggested that the recurrence of seven and its 
multiple, might indicate that the other two were also reckonings of 
some sort. Air 
Dr. Piers mentioned that there were many scratched drawings at 
Wagenaars Kraal, in the Nieuwveld, where some of the older drawings 
had been copied by subsequent natives. 
Dr. CorsToRPHINE exhibited a piece of limestone showing very 
typical cone-in-cone structure. It had been found on a débris heap 
at Kimberley and forwarded to the Museum by Mr. Gardner 
Williams. 
Dr. Corstorphine gave a short note on an old beach deposit on the 
site of the South African Brewery at Woodstock, which had been 
brought to his notice by Mr. A. W. Ackermann, Architect, Cape 
Town. 
Immediately adjacent to the railway, excavations for foundations 
have been made down to the underlying Malmesbury slate. The 
sections nearest town show a layer of shells and water-worn boulders, 
some 3 feet thick, resting on the slate and covered by about 
3 feet of sand and soil, but within 30 yards the deposit entirely 
thins out. The shells all belong to species found on the present 
beach, viz.: Lutraria oblonga, Bullia rhodostoma, B. Levigata, 
Patella argenvilli, Crepidula hepatica, Turritella knysneensis. 
A copy of a report on a submarine disturbance, from the Magis- 
trate at Walfish Bay, forwarded by Mr. Stanford, was read by the 
Secretary. The Magistrate stated that on May 31st or June Ist last, 
a new island appeared about 100 yards N.H. of Pelican Point. 
The island was about 150 feet long by 30 feet wide, and stood 
12 feet above high water. It was composed of a tenacious clay ; 
soundings gave 7-10 fathoms around it; steam was observed rising 
from the clay, and an intense smell of sulphuretted hydrogen was 
perceptible, even at a distance of 5 miles. 
Mr. W. L. ScuaTEr read a paper entitled, ‘‘ Notes on the so called 
‘Post Office Stone,’ and other inscribed stones preserved in the 
South African Museum and elsewhere.”
