He observes that organisms might have entered Needham's boiled broth before it was sealed from the air. In his experiment, the broth is boiled for more than 30 minutes in a flask that is already sealed; no "little animals" appear. His Prodromo d'une ouvrage sur les reproductions animales ("outline for a work on animal generation") describes his demonstrations.

Extractions: Teodolite equatoriale Un aspetto interessante dell'industria inglese produttrice di strumenti scientifici fu la comparsa, alla metà del Settecento, di grandi officine, che costruivano strumenti utilizzati in tutti i campi della ricerca scientifica. Scompare perciò la figura dell'artigiano, sostituita da quella dell'industriale e dell'operaio specializzato, mentre si differenziano le figure del tecnico e dello scienziato. Jesse Ramsden , (Salterhebble 1735 - Brighton 1800), fisico britannico e uno dei più importanti artigiani inglesi del sec. XVIII, fu attivo nei campi più disparati: costruttore di dispositivi di precisione, realizzò un micrometro filare utilizzato negli archi di misura dei sestanti e delle circonferenze geodetiche. Realizzò macchine a dividere e bilance di precisione , perfezionò strumenti ottici e teodoliti e costruì una macchina elettrostatica a strofinio. Divenne famoso soprattutto a partire dal 1770, quando cominciò a costruire strumenti astronomici. L'Istituto Idrografico della Marina conserva un teodolite equatoriale da campagna prodotto dopo il 1780 dal Ramsden, che modificò un esemplare descritto dal Van Short nel 1749. E' uno strumento per osservazioni astronomiche, con montatura altazimutale ed equatoriale, che consente la misurazione dell'ascensione retta e della declinazione delle stelle.

The Ramsden theodolite is a theodolite American English transit ) which was specially constructed for use in the first Ordnance Survey of Southern Britain . The theodolite was commissioned from Jesse Ramsden , a leading Yorkshire instrument maker, who had developed the technique of dividing angular scales accurately to within a second of arc . The instrument took three years to build, and had a base circle of 3 ft (914 mm) - it was also known as the Great or 36 inch theodolite. The full survey (sometimes called the Principal Triangulation of Great Britain ) was finally begun in by a team formed under General William Roy (d ); the survey used the new theodolite on a specially surveyed baseline , based on Roy's accurate surveys between London and Paris Traces of the theodolite support structure were still to be found many years afterwards at some remote survey points, such as at Soldiers' Lump, the summit of Black Hill in the Peak District of England.

Extractions: Jesse Ramsden was an eighteenth century English designer and manufacturer of mathematical and astronomical instruments. He is best known for the design of a telescope and microscope eyepiece (ocular) that bears his name and is still commonly used today. Born in Yorkshire, England, on October 6, 1735, Ramsden was the son of an innkeeper. As a young boy, Ramsden was apprenticed to a cloth worker, but in the long run, the textile industry did not interest him. At the age of 23 he apprenticed himself to a mathematical instrument maker and, in a very short time, Ramsden demonstrated that he was a brilliant and skillful designer of instruments. In just four years, he started his own business in London. Ramsden soon became acknowledged as the best designer and manufacturer of mathematical, astronomical, surveying and navigational instruments in England. Ramsden designed instruments of great accuracy, largely due to his invention of the dividing engine. Prior to his creation of the device, the division and inscription of scales on mathematical instruments was done by hand, but Ramsden's divider eliminated the risk of human error and made it feasible to inscribe lines accurate to a second of an arc. Due to the precision he could obtain, Ramsden's instruments were in great demand and he furnished achromatic telescopes equipped with accurately divided circles to many European observatories. Insisting on only the highest quality was problematic at times, however, since Ramsden had a reputation for completing the orders of his customers belatedly.

Extractions: Jesse Ramsden (1735-1800) Jesse Ramsden, the son of a Yorkshire innkeeper, was born October 6, 1735. At the age of 16 he was apprenticed, first to a cloth worker and later to a scientific instrument maker in London. By the time he finished his apprenticeship he was highly skilled in engraving and his reputation rapidly increased after 1762 when he opened his own business. A few years later he married Sarah Dollond, the youngest sister of Peter Dollond. Ramsdens inventive genius led to the development of a new universal equatoreal, two new micrometers, and a new construction of eyeglasses. A telescopic eyepiece of his design is still used today. But his most important and well-known invention was a new engine for dividing mathematical instrument scales. While the best dividers at that time achieved an accuracy of no better than 3 seconds of arc, Ramsdens divider made it possible to inscribe lines accurate to ½ second. The British government awarded him a handsome premium for this invention. By 1789 he and his workmen had constructed nearly a thousand sextants. He made important improvements in theodolites and transits, invented a pyrometer to measure thermal expension, and a device for determining telescopic powers. His most famous work was a five-foot vertical circle for the Palermo Observatory. Another well-known instrument from his shop was the four-foot diameter theodolite delivered to General William Roy for his survey to link the Paris and Greenwich Observatory meridians. This was done with unprecedented accuracy owing largely to Ramsdens theodolite.

Extractions: Entries covering Wrenthorpe and Silcoates in Local Trades Directories from 1853-1936 CONTENTS (click on the section you want) The local historian can derive valuable information from trades directories. These were the nineteenth century equivalent to the Yellow Pages, but gave more information than just lists of local companies. Each town and village has its own entry, which usually contains three types of information. Firstly there is a paragraph of general information about the area, a brief history, information about the local churches and schools along with details of the postal service. Next is a list of residents, which is followed by the main list of trades people in alphabetical order. Entries for Wrenthorpe from four old trades directories are printed below. It has to be remembered that as interesting as the entries are, they only provide us with limited information. Only the wealthiest residents are recorded and of these only the head of the household is listed. Some of the information may have been out of date at the time the directory was printed. The other most frustrating problem with village entries such as Wrenthorpe's, is the vagueness of the details. No precise address is given, there are no street numbers as there would be for businesses in towns and cities. At least we are given some indication due to ancient township boundary along the course of Foster Ford Beck and Balne Beck. Entries headed Silcoates therefore relate to Silcoates Lane, Wrenthorpe Lane (usually referred to as Sunny Hill) and Jerry Clay Lane which were in the old Alverthorpe-cum-Thornes township. Wrenthorpe entries are usually divided into Bragg Lane End, Potovens (meaning the present village centre to the East of the beck boundary) and Snow Hill (referring to the then isolated hamlet of properties near the Bay Horse PH).
