Description
Two figures to issue 235 of Philosophical Transactions of the Royal Society.
Fig. 1 Diagram showing the branch like structure of a ‘polypus of the lungs’ voided by a taylor.
Illustration to Two observations, one about the death of a dog on firing a volley of small shot: the other about the polypus of the lungs, communicated in a letter of Mr. Robert Clarke, to Dr. Martin Lister..., published in Philosophical Transactions of the Royal Society, vol.19, issue 235 (Dec 1697) pp.779-780. The original letter can be found in the Early Letters of the Royal Society, EL/C2/31.
Fig. 2 Diagram demonstrating Stephen Gray’s concave specula taking the form of a parabolic figure.
Key: ‘AB is the perimiter, CD the Axis, C the Focus, and D the Vertex, 1,2,3,4,5, the several Points in the Parabola, AFDBG the form of the suspended Line, AHDIB a portions of a Circle, which thought it pass through points ADB, is more from the other Points of the Parabola than the suspended Line.’
Illustration to A letter from Mr. Stephen Gray, dated Canterbury, Dec. 8.1697. relating some Experiments about making Concave Specula nearly of a Parabolick Figure, published in Philosophical Transactions of the Royal Society, vol.19, issue 235 (Dec 1697) pp.787-790.
