The endocrine pancreas of the rock bass (Ambloplites rupestris) was examined by light and electron microscopy. Two cell types with staining properties similar to mammalian A and B cells, and a third, non-staining cell type were found in the spherical pancreatic islets that were surrounded by a connective tissue capsule and embedded in two small masses of exocrine tissue. From an analysis of the ultrastructure of the A and B cells, a secretory cycle for each of these cell types was proposed. The secretory cycle of the A cell consisted of three well defined stages: (1) A cell production stage: during which A granule formation occurred in the sacs of the Golgi apparatus and the cell was characterized by the presence of numerous secretory granules, some elements of lamellar endoplasmic reticulum, and a homogeneously granular nucleus. The cytoplasm contained few distended cisternae, variable numbers of free ribosomes, microtubules and small vesicles. (2) A cell release stage: during which the release of A granules occurred and the cell usually contained several large distended cisternae and variable numbers of secretory granules. Granule release mechanisms included exocytosis, by which individual granules were released into the extracellular space after their membranes fused with the plasmalemma, and emiocytosis, by which one or more granules were released into a large cisterna whose membrane fused with the plasmalemma and formed a pore through which the cisternal contents passed out of the cell. (3) A cell reorganization stage: during which the changeover from the release stage to the production stage occurred and the reorganization of organelles and membrane structures took place. The cell contained few secretory granules and numerous small endoplasmic reticular cisternae. The cytoplasm exhibited less electron density than either of the other two stages. The A granule after formation underwent a series of morphological changes which were described in four numerically identified phases. The secretory cycle of the B cell consisred of two stages: (1) B cell production stage: during which the B granule formation occurred in the sacs of the Go1gi apparatus. The cell was characterized by an irregular outline, the presence of numerous secretory granules, and an irregularly shaped nucleus which contained variable amounts of clumped chromatin. The cytoplasm contained moderate amounts of lamellar endoplasmic reticulum studded with ribosomes, several small vesicles, and an active Go1gi apparatus. (2) B cell release stage: during which the release of B granules occurred. The cell contained a rounded nucleus with dispersed chromatin, several distended endoplasmic reticular cisternae and a variable number of secretory granules. Granule release occu~ by emiocytosis and exocytosis similar to that found for the A cell.

Edward Mirynech joined the faculty at Brock University in 1964 as assistant professor of Geology. Edward Mirynech, the son of John and Katherine Mirynech, grew up in St. Catharines, attended Connaught Public School and received his formal education at the University of Toronto. Dr. Mirynech played several critical roles in the early development of the University. In addition to teaching, Dr. Mirynech was also the acting director of the athletics department, a coach for many of the early rowing, hockey and basketball teams and served the University as marshall for the sod turning ceremony for the new DeCew campus in 1965. Dr. Mirynech was instrumental in the founding of the physical education, geography and geological sciences programs. He served as acting chairman in 1968 when the department of geological sciences enrolled its first students. Part of the unique teaching program was the annual field trips to locations such as the Belleville area, extended summer teaching programs held in Trinidad-Tobago and the following year in Iceland. In 1972, the first graduation ceremony ever to be held in the Arctic, at Pond Inlet, NWT, made national news. Three geology students, on a study trip to the Arctic, received their degrees during a special ceremony. Dr. Mirynech was among the faculty team in Pond Inlet, NWT, representing Brock University. Dr. Mirynech retired from teaching in 1985, and passed away in 2004.

On the 16th day of May, part of the deck and cargo consisting of lumber went overboard. The mainsail was lost and the jib was split due to the wind. All losses and damages should be borne by the merchants and whomever else it concerned and not by or through the insufficiency of the schooner of neglect by the officers and mariners. This is a 2 ½ page handwritten document, May 16, 1837.
