Then, after thirteen years, in 1869-72, an exact and extensive series of observations on the subject were made by the present Earl of Rosse.
So stood the case for a long time; it was settled to the satisfaction of Europe that there were two classes of nebulae, one that were worlds, one that were not, but only the pabulum of future worlds. Silence arose. A voice was heard, 'Let there be Lord Rosse! and immediately his telescope walked into Orion; destroyed the supposed matter of stars; but, in return, created immeasurable worlds.
With great respect for the Earl of Rosse, is it conceivable that he, or any man, by one hour's working the tackle of his new instrument, can have carried any stunning revolutionary effect into the heart of a section so ancient in our mathematical physics?
The next day we went as far as the Royal Palace of Woodstock, where King Ethelred formerly held a Parliament, and enacted certain laws. This palace, abounding in magnificence, was built by Henry I., to which he joined a very large park, enclosed with a wall; according to John Rosse, the first park in England.
The failure of 1845 did not prevent the people from planting potatoes very largely in 1846, in which year, according to one account, the quantity of land under potatoes in Ireland, was one million two hundred and thirty seven thousand four hundred and forty one acres; the produce being valued at £15,947,919 sterling; but according to another account it was very much larger, being, as estimated by the Earl of Rosse, two millions one hundred thousand acres, valued at £33,600,000.
Lord Rosse has now a competitor; and with a tube of eighty feet in length, and the power of looking direct at the distant object, may we not hope to hear of great discoveries by means of the new instrument?
Clark, of the Cambridge staff, resolved the Crab nebula in Taurus, which the reflector of Lord Rosse had never been able to decompose. It was the 22nd of November; the departure was to take place in ten days.
An especially fine cleft originates on the E. side of this crater, which, following an undulating course over the Mare Nectaris, terminates at Rosse, N. of Fracastorius.
He had a seat in the House of Commons, as member for King's County, from 1821 to 1834, his ancestral estate being situated in this part of Ireland. Lord Rosse was endowed by nature with a special taste for mechanical pursuits. Not only had he the qualifications of a scientific engineer, but he had the manual dexterity which qualified him personally to carry out many practical arts.
The first, constructed by Herschel, was 36 feet in length, and had an object-glass of 4 feet 6 inches; it magnified 6,000 times; the second, raised in Ireland, at Birrcastle, in Parsonstown Park, belonged to Lord Rosse; the length of its tube was 48 feet and the width of its mirror 6 feet; it magnified 6,400 times, and it had required an immense erection of masonry on which to place the apparatus necessary for working the instrument, which weighed 12-1/2 tons.
