It is not a case of drawing a straight line from one extreme to the other, and finding the middle point by bisection.
Mr. Frazer does not here pretend to guess why the bisection occurred.
For the diameters, bisect each side and connect the points of bisection.
Bacteria increase by bisection, and when the surrounding conditions are favorable their rate of production is marvellous.
The process of bisection is one which can, theoretically, be carried on for ever, without any last term being attained.
Before the bisection is motion; after the bisection is rest.
Two of these lines connect the opposite angles, and two the sides at the point of bisection.
That is my own opinion: though I do not hold it for Mr. Spencer's reasons, or believe in any 'bisection.'
The 'bisection' of his theory could not, I fear, be 'gradual.'
Mitreing consists of halving the angle and making each piece to fit the line of bisection.
