A study of thermal decompositions of an allylic hydroperoxide /|nby Thomas A. McCarrick. -- 260 St. Catharines [Ont.] : Dept. of Chemistry, Brock University,

The thermal decomposition of 2,3-di~ethy l - J-hydr operox y- 1 - butene , p r epared f rol") singl e t oxygen, has been studied i n three solvents over the tempe r a ture r ange from 1500e to l o00e and t!1e i 111 t ial ~oncentrfttl nn r Ange from O. 01 M to 0.2 M. Analys i s of the kine tic data ind ica te s i nduced homolysis as the n ost probRble mode of d e composition, g iving rise to a 3/2 f S order dependence upon hy d.roperoxide concent :r8.tl on . Experimental activation e nergies for the decomposition were f ound to be between 29.5 kcsl./raole and 30.0 k cal./mole .• \,iith log A factors between 11 . 3 and 12.3. Product studies were conducted in R variety of solvents a s well as in the pr esence of a variety of free r adical initiators . Investigation of the kinetic ch a in length indicated a chain length of about fifty. A degenerat i ve chain branching mechanism 1s proposed which predicts the multi t ude of products which Rre observed e xperimentally as well as giving activation energies and log A factors si~il a r to those found experimentally .

Reduced local energy calculations on X¹Sigmaâ ½gHâ and 1¹S He /|nGerald F. Thomas. -- 260 St. Catharines [Ont.] : Dept. of Chemistry, Brock University,

The one-electron reduced local energy function, t ~ , is introduced and has the property < tL)=(~>. It is suggested that the accuracy of SL reflects the local accuracy of an approximate wavefunction. We establish that <~~>~ <~2,> and present a bound formula, E~ , which is such that where Ew is Weinstein's lower bound formula to the ground state. The nature of the bound is not guaranteed but for sufficiently accurate wavefunctions it will yield a lower bound. ,-+ 1'S I I Applications to X LW Hz. and ne are presented.

Irish John Willson United Empire Loyalist Family Fonds

John Willson first came to Upper Canada along with his friend Nathaniel Pettit in the late 1700s. They both moved with their families from New Jersey where they had both been imprisioned for not siding with the rebels and maintaining Loyalist allegiences. Pettit arrived with his four daughters, leaving his son behind. Willson came with his wife and nine children. Willson received 1200 acres of land as well as 200 per child. He settled at the corner of Dorchester road and Thorold Stone Road, where he and his family did very well for themselves. Willson as well as his son Thomas ran ox-teams on the portage. His son John became the proprietor of the Exchange hotel at Niagara, and Charles operated at the Pavilion hotel at Falls View. Shortly after his arrival in Upper Canada John Willson changed his name to “Irish” John Willson, as there were 5 other “John Willsons” which appeared on the Loyalists lists. Irish John drowned in the Niagara River in 1798, and his family continued to thrive in Niagara after his death. His second son Thomas Willson, married Abigail Pettit, daughter of his Father’s friend Nathaniel. Thomas was awarded 250 acres of land as a Loyalist and 200 for Abigail, as she was the daughter of a loyalist. He became a blacksmith and also operated ox-teams along the portage. He was Assessor for Stamford Township for 1800, 1807, 1820 and 1829. During the years 1808, 1822, 1825, 1826 and 1831 he was a tax collector and overseer of Statute of Labour. Thomas and Abigail Willson had nine children together. Francis Bond Head Willson of Beaverdams (mentioned throughout the collection) was a great grandson of Thomas and Abigail. Thomas and his wife are both buried beside the Lundy’s Lane United Church. *for more information on the remaining Willson family please refer to box #1, folders 1-3. * Genealogical information from a paper prepared by Pearl Wilson and given before the Lundy’s Lane Historical Society, May 1945, by Hazel Culp Ferris.

Two Black Gentlemen Photographed by John Cooper, London/St. Thomas, Ont. [n.d.]

An undated cabinet card of two Black men photographed by John Cooper, who operated as a photographer in London, Ont. and St. Thomas, Ont. from 1857 - 1890. The reverse of the photograph features the photographer's stamp in coloured ink. This photograph was in the possession of Iris Sloman Bell, of St. Catharines. The Sloman - Bell family have relatives who include former Black slaves from the United States. John Cooper is listed as a photographer and daguerrean artist in 1857 - 1890 in London, Ont. and in 1874 in St. Thomas, Ont. Source: Phillips, Glen C. The Ontario photographers list (1851-1900). Sarnia: Iron Gate Publishing Co., 1990. "Cabinet card photographs were first introduced in 1866. They were initially employed for landscapes rather than portraitures. Cabinet cards replaced Carte de visite photographs as the popular mode of photography. Cabinet cards became the standard for photographic portraits in 1870. Cabinet cards experienced their peak in popularity in the 1880's. Cabinet cards were still being produced in the United States until the early 1900's and continued to be produced in Europe even longer. The best way to describe a cabinet card is that it is a thin photograph that is mounted on a card that measures 4 1/4″ by 6 1/2″. Cabinet cards frequently have artistic logos and information on the bottom or the reverse of the card which advertised the photographer or the photography studio's services."
