Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

This thesis explores two distinct applications of laser spectroscopy: the study of nuclear ground state properties, and element selective radioactive ion beam production. It also presents the methods and results of an investigation into isotope shifts in the mercury isotopic chain. These Resonance Ionization Laser Ion Source (RILIS) developments are detailed, together with an RILIS ionization scheme that allowed laser ionized ion beams of chromium, germanium, radium and tellurium to be generated at the Isotope Mass Separator On-Line (ISOLDE) facility. A combination of laser spectroscopy with decay spectroscopy and mass spectrometry unambiguously demonstrated a cessation of the extreme shape staggering first observed in the 1970s and revealed the characteristic kink at the crossing of the N=126 shell closure. A series of RILIS developments were required to facilitate this experiment, including mercury "ionization scheme" development and the coupling of the RILIS with an arc discharge ion source. Laser spectroscopy has since become a powerful tool for nuclear physics and the Resonance Ionization Laser Ion Source (RILIS), of the ISOLDE facility at CERN, is a prime example. Highlighting important advances in this field, the thesis offers a unique and revealing resource.

Among the earliest novels written about children, for children, The History of Sandford and Merton was enormously popular for a century and a half after its first publication in 1783-9. The novel is Enlightenment for beginners, offering a course of education in class, race, and gender to its six year-old protagonists, the robust farm-boy Harry Sandford and Tommy Merton, the spoiled boy from the big house. Sandford and Merton offers entertaining and practical lessons in manners, masculinity, and class politics. This Broadview Edition includes the original illustrations, along with contemporary reviews and other material on childhood by John Locke, Thomas Day, Jean-Jacques Rousseau, and others.
