were to start in any direction whatever, and move in that direction in a 
perfect straight line according to the definition of Leibnitz; after travelling 
a most prodigious distance, to which the parallactic unit—200,000 times 
the diameter of the earth’s orbit—would be only a few steps, you would 
arrive at—this place. Only, if you had started upwards, you would appear 
from below. Now, one of two things would be true: either, when you had 
got half way on your journey, you came to a place that is opposite to this, 
and which you must have gone through, whatever direction you started 
in; or else, all paths you could have taken diverge entirely from each other 
till they meet again at this place. In the former case, every two straight 
lines in a plane meet in two points; in the latter, they meet only in one. 
Upon this supposition of a positive curvature, the whole of geometry is far 
more complete and interesting; the principle of duality, instead of half 
breaking down over metric relations, applies to all propositions, without 
exception. In fact, I do not mind confessing that I, personally, have often 
found relief from the dreary infinities of homaloidal space in the consoling 
hope that, after all, this other may be the true state of things.” 
ArT. XXV.—Further Notes on Moa Remains. By C. H. Ronson. 
With Plates. 
[Read before the Wellington Philosophical Institute, 24th February, 1877.] 
A errar deal has been said and written to prove that the Moa was hunted 
and eaten by the present race of Maoris, and the reverse. Some of the 
papers, however, read before this Society during the last year, quite settle 
that question; proving beyond a doubt that the Moa-hunters were Maoris, 
such as we see about us at the present time. There is another point of 
some interest as yet unsettled, namely, what tribes hunted the Moa, and 
how they hunted him. I hope to be able to show who were the Moa- 
hunters in the vicinity of Cape Campbell. In a paper * read before this 
Society, about a year ago, on some Moa remains found near and on the 
Cape, I stated that up to that time I had not discovered any traces of Moa- 
hunters. I was afterwards fortunate enough to come upon some of their 
old ovens, so near the sea that it is probable that others have been washed 
away. Those which remain are situated on the sand-bar between Lake Grass- 
mere and the sea, near some ponds, and only a few yards from high-water 
mark. All the Moa bones found in these ovens were very much broken, 
and were chiefly leg bones of various kinds. I did not meet with a single 
head or sternum, and only a few vertebre and parts of pelves. There were,
