B.N. Peach letter, 1918.

Ben N. Peach (1842-1926) was a well-known geologist whose work focused on the geological structure of Scotland, and in particular the Northwest Scottish Highlands and Southern Uplands. He formed a close working relationship with John Horne and the two colloborated on many works, most notably two memoirs of the Geological Survey of Great Britain, The Silurian Rocks of Britain (1899) and The Geological Structure of the North-West Highlands of Scotland (1907).

A roll of non-commissioned Officers, Drummers, & Private men enlisted for the first Battalion of the King’s Royal Regiment of New York, 1781 [photocopy]

The King’s Royal Regiment of New York was a Loyalist regiment that served on the Canadian frontier during the American Revolutionary War. The regiment was commanded by Sir John Johnson, who recruited members from the settlers on his estates in the Mohawk Valley. After the War, the two battalions of the regiment were disbanded. The First Battalion settled on the north shore of the St. Lawrence, while the Second Battalion settled by the Bay of Quinte.

Royal Bank of Canada records, 1973-1977

In 1973, the Royal Bank of Canada began construction on a new office in downtown Toronto known as the Royal Bank Plaza. The $100 million construction project consisted of two triangular office towers linked by a glass-enclosed banking hall. In addition to housing the Royal Bank of Canada’s Ontario headquarters, the Plaza included a two-level shopping concourse with restaurants and boutiques, as well as office space available for lease. The Plaza officially opened on March 10, 1977.

Cyclotetrasiloxane Frameworks for the Chemoenzymatic Synthesis of Oligoesters

Immobilized lipase B from Candida antarctica (Novozym® 435, N435) was utilized as part of a chemoenzymatic strategy for the synthesis of branched polyesters based on a cyclotetrasiloxane core in the absence of solvent. Nuclear magnetic resonance spectroscopy and matrix-assisted laser desorption ionization time-of-flight mass spectrometry were utilized to monitor the reactions between tetraester cyclotetrasiloxanes and aliphatic diols. The enzyme-mediated esterification reactions can achieve 65– 80% consumption of starting materials in 24–48 h. Longer reaction times, 72–96 h, resulted in the formation of cross-linked gel-like networks. Gel permeation chromatography of the polymers indicated that the masses were Mw ¼ 11 400, 13 100, and 19 400 g mol 1 for the substrate pairs of C7D4 ester/ octane-1,8-diol, C10D4 ester/pentane-1,5-diol and C10D4 ester/octane-1,8-diol respectively, after 48 h. Extending the polymerization for an additional 24 h with the C10D4 ester/octane-1,8-diol pair gave Mw ¼ 86 800 g mol 1. To the best of our knowledge this represents the first report using lipase catalysis to produce branched polymers that are built from a cyclotetrasiloxane core.
