Aa1-19	Aa1-21	Aa1-25	Aa1-31	Aa1-36
a.m.		noon	p.m.

The power of the sun is gradually diminishing from the powerfully drawn a.m. tapa mea pair over the single noon glyph (with 25 = 5 * 5), to the slimmer p.m. pair.

Metoro has also distinguished them, judging from his words:

Aa1-19	Aa1-21	Aa1-25	Aa1-31	Aa1-36
i uhi tapamea	e uhi tapamea	e uhi tapamea	e uhi tapamea	e uhi tapamea

These are the only tapa mea glyphs where he said uhi tapamea. The remaining 5 are beautifully arranged too:

Aa1-17 (4)	Aa1-23	Aa1-27 (13)	Aa1-29	Aa1-34 (19)
ka tapamea	e hokohuki	ki te henua	ma te hokohuki	te tapamea
