Subsequent to Boyle the colours of thin plates occupied the attention of Robert Hooke, in whose writings we find a dawning of the undulatory theory of light. He shows very clearly the dependence of the colour upon the thickness of the film, and proves by microscopic observation that plates of a uniform thickness yield uniform colours.
No sooner were these discoveries given to the world than they were opposed with a degree of virulence and ignorance which have seldom been combined in scientific controversy. The most distinguished of his opponents were Robert Hooke and Huyghens. Both attacked his theory from the standpoint of the undulatory theory of light which they upheld. II. The Colours of Natural Bodies
Put fate into his hand? into his will Our lives and fortunes? howle and crye to our owne clay "Be mercifull, ô Prince?" ô, pittied people! Base, base, poore patch men! You dare not heare this; You have sold your eares to slavery; begon and flatter. When ere your politick Prince putts his hooke into my nose Here must he put his Sword too. Bred. We lament ye. Enter the Son. Son. We are undon, Sir.
Travellers that are weary have sleepe led in a string. Buz. So doe those that are hangd: all that travell & are weary doe not sleepe. Man. Why, Mr. Buzzano, why? Buz. Midwives travell at night & are weary with eating groaning pyes , & yet sleepe not: shall I hooke you? Man. Hooke me? what meanst? Buz. These Taylors are the wittyest knaves that live by bread. Hen.
The next year we find our young astronomer starting for a Continental tour, and we, who complain if the Channel passage lasts more than an hour or two, may note Halley's remark in writing to Hooke on June 15th, 1680: "Having fallen in with bad weather we took forty hours in the journey from Dover to Calais."
He was acting only ministerially. I apprehended, however, that Hooke was bound to give his best advice. I speak as a lawyer. Though I have had clients whose causes I could not, as a private man, approve; yet, if I undertook them, I would not do any thing that might be prejudicial to them, even at their desire, without warning them of their danger.
Hooke and Ninnis on several evenings at about 11 o'clock have heard what happened to be faint messages, but unreadable. He sent word to Macquarie Island of this in hopes that they would hear and increase the power. "June 20. During this last blow with its accompanying drift-snow there has been much leakage of current from the aerial during the sending of reports.
Hooke, the first "curator and experimenter" of the Royal Society, with ample materials for discourse before half a dozen meetings of that body; and that, to say truth, except for the progress of natural knowledge, we should not have been able to make even the tools by which these machines are constructed.
They were next seen by Hooke and Cassini in 1666, and this time with sufficient distinctness to serve as indexes to the planet's rotation, determined by the latter as taking place in a period of twenty-four hours forty minutes. Increased confidence was given to this result through Maraldi's precise verification of it in 1719.
This is a matter which has been quite unknown to those who hitherto have begun to consider the waves of light, amongst whom are Mr. Hooke in his Micrographia, and Father Pardies, who, in a treatise of which he let me see a portion, and which he was unable to complete as he died shortly afterward, had undertaken to prove by these waves the effects of reflexion and refraction.
