aforesaid chamber with the lowest point beneath the low-water 
level of the Mle. "We thus get the normal proportion of radius 
to diameter for the internal construction of this very ancient 
building. 
I should like to observe, whilst on the subject of the Great 
Pyramid— undoubtedly one of the most suggestive of all ancient 
buildings — that the tripartite division observable therein, viz., the 
sunken well, the queen's chamber, and the king's chamber, with 
the crowning part above the last, culminating in the head-stone, 
or, as it is called, the stone of stumbling, exactly corresponds to 
the well-known division in Eastern architecture of " heaven, the 
region of the gods," the " sub-celestial region of the demigods," 
and of "the subterranean regions of hell;" and I am inclined to 
believe that this division is the secret of the internal structure of 
the pyramid. Let me only observe finally that the name of the 
curious construction known in our own Gothic architecture as the 
crypt is only a Greek form of the Anglo-Saxon hell, and corresponds 
entirely to the subterranean vault found under the pyramid, and 
also supposed, in theory at least, to represent the place "of the 
dead," as hades or hell, or sheol, in other religious systems. 
I intend to dwell no further on this part of my subject, as it 
relates to the connection between our rude stone monuments in 
Cornwall and the most perfect of all buildings, the pyramid and 
stupas of India, derived from a mutual agreement with some of 
the first principles of the natural world, but to pass on at once to 
another subject of considerable interest at the present moment. 
Before doing so, however, I may perhaps be allowed to raise a 
question of some interest to us locally — I mean the correct deriva- 
tion of the word Dosmerry in " Dosmerry Pool." To say that 
" doz" and "rauir" mean, in Scotch Gaelic, "drop" and "sea" 
would scarcely satisfy the requirements of Celtic grammar in 
words placed thus in government. We could only have " na- 
muir doz" for drop of the sea. Besides this, the raison (Petre of 
such an origin appears wanting ; for why Dosmerry Pool should 
be more a drop of the ocean than any other pool, is not so evident ; 
but if we derive it from the true British dur= u water," and 
smaire = " black," and thus get a compound, "Dursmaire" or 
Black Water, we have at once a grammatical compound, and 
also a true descriptive title of the pool itself. I need only remind 
you that this title of Black Water is constantly given to deep and
