Dr. Peeinguey exhibited some facsimile of Bushman paintings 
published in colour in 1838, and probably taken in 1830. These paint- 
ings were traced anew in 1872, and were copied again last year. The 
colour of the originals had not faded in the least. The great resistance of 
the pigment to the sundry destructive agencies, as evinced in the present 
case, was a point of great importance, as it justified the antiquarian in 
assigning to these reproductions a greater age than would be anticipated 
from the fragility of these paintings. We know also of the wonderful 
preservation of similar frescoes in the lately discovered caves of Almadira 
in Portugal, or in the Landes and Dordogne in France. Although these 
Bushman pictures were in all likelihood of a much more recent period, it 
was impossible at present to assign them a date. He could only say that 
all, or nearly all those he knew of, found in the western part of South 
Africa represented only the ferm naturce of the country ; whereas many of 
those occurring in the eastern part of Cape Colony contained representa- 
tions of domesticated animals — horse, cattle, dog. He doubted if many of 
these were the work of the same race that painted in the west. 
He exhibited also bones of large animals, such as the ox, possibly the 
eland, &c., found in a cavern lately discovered, the fractured parts of 
which might have been caused by the gnawing of wild beasts ; two large 
horn cores, however, probably used as clubs, and a calcined bone, of 
which the marrow had been extracted, testified to man's agency. 
Dr. A. W. Rogers read a " Note on the Structure of Tygerberg, Prince 
Albert." He observed that in 1906 Dr. Sandberg had published a paper 
throwing doubt on the anticlinical structure of Tygerberg as described 
by Mr. A. R. Sawyer and Professor E. H. L. Schwarz. The two latter 
geologists found the range to be the top of a sharp fold of Witteberg beds 
projecting along the middle of an anticline in the Dwyka and Ecca Series. 
Dr. Sandberg came to the conclusion that Tygerberg was the northern 
extremity of a fold which had its root in the foothills of the Zwartbergen, 
and which had been bent northward over younger beds (Lower Karoo), so 
that the crest of the fold was now a trough separated from the main mass 
of the Witteberg beds by denudation. He laid stress on the occurrence of 
masses of quartzite supposed to be pieces of the Witteberg Series discon- 
nected by denudation from the Tygerberg mass, in the Dwyka area ; and 
also on the supposed occurrence of Witteberg beds in an inverted position 
in the valley of the Sand River, where the remains of the former con- 
necting link between Tygerberg and the foothills should be found. Dr. 
Sandberg had recently restated his views in the Geological Magazine, and, 
as the point in dispute affected the interpretation of a far wider area than 
the Tygerberg locality, he (Dr. Rogers) spent a week in the country 
between Prince Albert and the east end of the Tygerberg, in order to 
study the evidence for Dr. Sandberg's views. It seemed to him that the
