I would like to report that there is a method describing geometric parameters of the round robin (cycles) figures both in two and in three measurements. Essence of the method: used coordinates point interesting for investigator usually they rest upon external border of the organ, bodies is conducted harmonic decomposition parameter to protuberances and unevenness on several harmonicas, for instance on three. It is under taken into account detour from correct symmetrical cycle. The printout of the program contains the factors to symmetries for axises getting through the centre of the cycle. There are: 1) proturberance (relief) 2) unevenness (dispersion on the edge), 3) anglers, 4) dissymmetry (of all cycle)

As example used to leaves Betula. I suppose that method can be useful for description population and the individual features Animalia better then for plants, (least accumulate too much factors). I assume that absence or presence of the sign (for instance at description pleural among insects) means the difficulty to applicability of the method.

The insufficiency of the method: base form from which scanning the deflections implies round robin (cycle) figure. However in nature it (cycle) rather widespread.

That do You think on the method.
Aside from description think it can be used in morphological differentiation both in phylogenic, as well in genetic.

Sincerely yours
