The draftsmen had spent hours preparing the surfaces of paper, straining ink through filters, honing drawing pens with emery and polishing them with rouge, drawing practice lines and scrutinizing them with powerful bench microscopes.
The why was evident enough in the heterogeneous mass crumpled prints, blank drawing-paper, and maps heaped ruinously over and under books, stuffed birds, geological specimens, dislocated microscopes, pieces of Roman pavement, curiosities innumerable and indescribable; among which roamed blotting-books, memorandum-books, four pieces of Indian rubber, three pair of compasses, seven paper-knives, ten knives, thirteen odd gloves, fifteen pencils, pens beyond reckoning, a purse, a key, half a poem on the Siege of Granada, three parts of an essay upon Spade Husbandry, the dramatis personae of a tragedy on Queen Brunehault, scores of old letters, and the dust of three years and a half.
This micro-universe is rooted and grounded in a mental base. Positively and without hope of overthrow, this assertion is made the flying particles know where to go. Coarse particles, those visible in old-time microscopes, when suspended in liquids, were observed to be in rapid motion, darting to all geometrical directions with high speed.
Besides Wilkins, Wren, Wallis, eminent mathematicians, Hooke, an accurate observer by microscopes, and Sydenham, the restorer of true physic, there flourished during this period a Boyle and a Newton; men who trod with cautious, and therefore the more secure steps, the only road which leads to true philosophy.
Those little lenses in their silver mountings, all ground and set and fashioned by his own hand, showed him the blood-globules, and the "pipes" of the teeth, which Purkinje and Retzius found with their achromatic microscopes a century later. We honor his skill and sagacity as they deserve; but a little trick of Mr.
Loads of scientific gentlemen worked away at me with microscopes, hammers, acids, and all sorts of tests, to decide what I was; and kept up such a fire of long words that I was 'most dead. They couldn't make up their minds; and meanwhile news of the strange thing spread, and every sort of person came to see me.
The members play at chess and draughts, and use the stereoscopic views, microscopes, and telescopes placed in the libraries. No special arrangements have been made to promote temperance; but the news-rooms and library exercise a powerful and beneficial influence in promoting sobriety.
Johnson answered, that he was an ingenious man, but had no veracity; and immediately mentioned, as an instance of it, an assertion of that writer, that he had seen objects magnified to a much greater degree by using three or four microscopes at a time, than by using one.
Back of it must be men great men. I am anxious that the modern school have the modern equipment demanded to serve the present age. But I am more anxious that each student come in vital touch with great men. We get life from life, not from laboratories, and we have life more abundantly as our lives touch greater lives. A school is vastly more than machinery, methods, microscopes and millions.
When a portion of any animal or vegetable body is infused in water, it gradually softens and disintegrates; and, as it does so, the water is found to swarm with minute active creatures, the so-called Infusorial Animalcules, none of which can be seen, except by the aid of the microscope; while a large proportion belong to the category of smallest things of which I have spoken, and which must have looked like mere dots and lines under the ordinary microscopes of the eighteenth century.
