The armorial bearings for Brock University, or more simply the University Coat of Arms, or crest, was designed in a large part by Presdent Gibson, assisted by other members of the Board of Governors (A preliminary design can be seen here). The Coat of Arms was granted to Brock University on March 17th, 1965. The Coat of Arms consist of an eagle, taken from General Brock’s own arms, displayed against a scarlet background - one of the official colours of Brock University. Immediately above it on a chief argent is displayed a maple-leaf (for Canada), a scallop shell (from the Lincoln and Welland regiment), and a trillium (for the province of Ontario). An open book fronts the eagle representing learning and knowledge. The crest itself is made up of a torch symbolizing learning, surrounded by a serpent for wisdom, with two calumet or North American pipes of peace, to symbolize Canada, friendship and agreement. The supporters consist of a beaver on the dexter side, emblematic of Canada and representing work and industry in learning. On the sinister side, a brock or badger (also in commemoration of General Brock) represents tenacity of purpose. The motto 'Surgite' is visible just below the arms.

A simple method was developed for treating corn seeds with oxamyl. It involved soaking the seeds to ensure oxamyl uptake, centrifugation to draw off excess solution, and drying under a stream of air to prevent the formation of fungus. The seeds were found to have an even distribution of oxamyl. Seeds remained fungus-free even 12 months after treatment. The highest nonphytotoxic treatment level was obtained by using a 4.00 mg/mL oxamyl solution. Extraction methods for the determination of oxamyl (methyl-N'N'-dimethyl-N-[(methylcarbamoyl)oxy]-l-thiooxamimidate), its oxime (methyl-N',N'-dimethyl-N-hydroxy-1-thiooxamimidate), and DMCF (N,N-dimethyl-1-cyanoformanade) in seed" root, and soil were developed. Seeds were processed by homogenizing, then shaking in methanol. Significantly more oxamyl was extracted from hydrated seeds as opposed to dry seeds. Soils were extracted by tumbling in methanol; recoveries range~ from 86 - 87% for oxamyl. Root was extracted to 93% efficiency for oxamyl by homogenizing the tissue in methanol. NucharAttaclay column cleanup afforded suitable extracts for analysis by RP-HPLC on a C18 column and UV detection at 254 nm. In the degradation study, oxamyl was found to dissipate from the seed down into the soil. It was also detected in the root. Oxime was detected in both the seed and soil, but not in the root. DMCF was detected in small amounts only in the seed.

The interior layered deposit (ILD) in Ganges Chasma, Valles Marineris, is a 4.25 km high mound that extends approximately 110 km from west to east. The deposition, deformation, and erosion history of the Ganges ILD records aids in identifying the processes that formed and shaped the Chasma. To interpret structural and geomorphic processes acting on the ILD, multiple layer attitudes and layer thickness transects were conducted on the Ganges ILD. Mineralogical data was analyzed to determine correlations between materials and landforms. Layer thickness measurements indicate that the majority of layers are between 0.5 m and 4 m throughout the ILD. Three major benches dominate the Ganges ILD. Layer thicknesses increase at the ILD benches, suggesting that the benches are formed from the gradual thickening of layers. This indicates that the benches are depositional features draping over basement topography. Layer attitudes indicate overall shallow dips generally confined to a North-South direction that locally appear to follow bench topography. Layering is disrupted on a scale of 40 m to 150 m in 12 separate locations throughout the ILD. In all locations, underlying layering is disturbed by overlying folded layers in a trough-like geometry. These features are interpreted to have formed as submarine channels in a lacustrine setting, subsequently infilled by sediments. Subsequently, the channels were eroded to the present topography, resulting in the thin, curved layering observed. Data cannot conclusively support one ILD formation hypothesis, but does indicate that the Ganges ILD postdates Chasma formation. The presence of water altered minerals, consistently thin layering, and layer orientations provide strong evidence that the ILD formed in a lacustrine setting.

Woodruff coat of arms (rough sketch - labeled), including a letter to Margaret from “Uncle Tom” regarding the coat of arms. Also included are 4 small cards and one Easter card bearing the coat of arms. [The Woodruff/Woodroffe crest originated in England. Sit Dux Sapientia (Wisdom be our guide). The arm holding a plant is supposed to be a dexter [right] arm, bent, holding a branch of honeysuckle vertically. Some members of the family believe that the plant is actually woodruff], Jan. 18, 1926.

Drawing and explanation of the Cleveland Family coat of arms. Pro Deo et Patria means For God and Country. The name is Saxon in origin and in 1403 the “de” was dropped from the name. The drawing and text are said to be from Cleveland Genealogy by J.B. Cleveland, 1881. It can also be found in An Account of the Lineage of General Moses Cleaveland (founder of the city of Cleveland, Ohio) of Canterbury, compiled by H.G. Cleveland, n.d.
