Page 75 - A circle is a plane figure contained by one line, which is called the circumference, and is such that all straight lines drawn from a certain point within the figure to the circumference, are equal to one another.
Page xi - Remembering that this Association is a popular Association, not a secret confraternity of men jealously guarding the mysteries of their profession, but inviting the uninitiated, the public at large, to join them, having as one of its objects to break down those imaginary and hurtful barriers which exist between men of science and so-called men of practice...
Page 75 - A diameter of a circle is a straight line drawn through the centre, and terminated both ways by the circumference.
Page 26 - Rule. — Multiply half the circumference by half the diameter, and the product will be the area.
Page vii - ... witnesses were cunningly imposed upon, or the wizard himself deluded. If the most numerous ship's company were all to asseverate that they had seen a mermaid, would any rational persons at the present day believe them? That they saw something which they believed to be a mermaid, would be easily conceded. No amount of attestation of innumerable and honest witnesses would ever convince any one, versed in mathematical and mechanical science, that a person had squared the circle or discovered perpetual...
Page xxii - ... equal to the right angles in the others, and the angle at C forms the angle at the base to every one of the three triangles, that is, it is common to all the three ; and as all the angles of a plane triangle are together equal to two right angles (Art. 5) the remaining or third angle must be equal in all the triangles ; for that angle is the complement (Art. 5) of the angle at C in each of the triangles. Now all plane triangles which are equiangular, have the sides which contain the corresponding...
