Dr. R. Maruotu read the following note explanatory of the 
Walfish Bay mud island, described by Mr. I. W. Waldron at the 
last meeting: ‘“‘ The formation of the mud island is probably quite 
independent from the patches of sulphur known to exist in the 
neighbourhood of Walfish Bay. From the fact that the gas was 
seen bubbling through the water it seems hardly hkely that it 
was pure sulphuretted hydrogen, which is very soluble in water. 
Unfortunately, no sample of the gas was collected. I think it very 
probable that the gas was marsh gas mixed with some sulphuretted 
hydrogen. Both these gases are formed when seaweed is decaying 
at the exclusion of air, hence there would be nothing else required 
to account for the whole phenomenon than to suppose that quan- 
tities of seaweed were buried in the locality under a very thick 
layer of mud—conditions which may be taken to exist along that 
coast.”
