This thesis attempts to clarify what Heidegger meant by the term "thinking" (Denken), where this ^'meanr is submitted in the double sense: firstly, in the sense of what Heidegger intended by the use and exposition of this term that we find in his lecture series. Was Heisst Denken?, where Heidegger quickly makes it clear that this intention is to actually bring thinking on the way, viz. making provision for the leap into thinking, and where this intention was carried out with the employment of a specific guiding phrase. In the second sense, it is an attempt at clarifying the meaning of the term. But this is not to say that we are here simply out to see how Heidegger defines the word '*thinking." It is in fact precisely within such definitive discourse that thought dies out. It is not merely be a case of defining a word, because this enterprise would be just as shallow as much as it would be unworkable. It is for this reason that Heidegger decided to establish for himself the task, not merely of explaining thinking as something to be beheld at a distance, but rather of bringing thinking underway by means of his lecture, proclaiming that, "Only the leap into the river tells us what is swimming. The question 'What is called thinking?' can never be answered by proposing a definition of the concept thinking, and then diligently explaining what is contained in that definition." (WCT, 21) This being Heidegger's intention, in order to understand Heidegger in his treatment of the term thinking, it is clear that we must also undergo an experience with thinking. It is in this spirit that the present work was written so as to collaborate the two senses of what Heidegger meant by "thinking."

The formation of the Sar Cheshmeh porphyry Cu-Mo deposit is related to the culmination of calc-alkaline igneous activity in the Kerman region. The deposit comprises a suite of Late Cenozoic intrusive sub-volcanic and extrusive rocks emplaced into a folded series of Eocene andesitic lavas and pyroclastic sediments. The earliest stage of magmatism was emplacement of a large granodiorite stock about 29 m.y.b.p. This was followed by intrusion of two separate porphyritic bodies at 15 (Sar Cheshrneh porphyry) and 12 m.y.b.p. (Late porphyry) and a series of sub-volcanic dikes between 12 and 9 m.y.b.p. Magmatic activity terminated with multi-phase extrusion of a Pelean dacitic dome complex between 10 and 2.8 m.y.b.p. The country rocks and the earlier porphyritic intrusions are pervasively altered to biotite-rich potassium silicate (metasomatic and hydrothermal) sericite-clay, phyllic and chlorite-clay, argillic assemblages. These grade outwards to an extensive propylitic zone. Within the ore body, the later intra-. and post-mineral dikes only reach the propylitic grade. At least three different sets of quartz veins are present, including a sericite-chlorite-quartz set which locally retrogrades pervasive secondary biotite to sericite. In the hypogene zone, metasomatic and hydrothermal alteration is related to all stages of magmatism but copper mineralization and veining are restricted to a period of 15 to 9 m.y.b.p.related to the early intrusive phases. The copper mineralization and silicate alteration do not fit a simple annular ring model but have been greatly modified by, 1. The existence of an ititial, outer ring, of metasomatic alteration overprinted by an inner.ring of hydrothermal alteration and, 2. later extensive dilating effects of intra- and post-mineral dikes. The hydrothermal clay mineral assemblage in the hypogene zone is illite-chlorite-kaolinite-smectite (beidellite). Preliminary studies indicate that the amount of each of these clays varies vertically and that hydrothermal zonation of clay minerals is possible. However, these minerals alter to illite-kaolinite assemblages in the supergene sulfide zone and to more kaolinite-rich assemblages in the supergene leached zone. Hydrothermal biotite breaks down readily in the supergene zone and is not well preserved in surface outcrops. The distribution of copper minerals in the supergene sulfide enrichment zone is only partly related to rock type being more dependent on topography and the availability of fractures.

Basal body temperature (BBT) and thermoeffector thresholds increase following ovulation in
many women. This study investigated if solely central thermoregulatory alterations are responsible.
Seven females in a non-contraceptive group (NCG) were compared with 5 monophasic contraceptive
users (HCG) on separate accounts: pre-ovulation (Trial I; d 2-5) and post-ovulation (Trial 2; 4-8 d
post-positive ovulation) for NCG, and active phase for HCG (d 2-5, d 18-21). During immersion in
28°C water to the axilla, participants exercised for 20-30 min on an underwater ergometer. After
steadily sweating, immersion continued until metabolism increased two-fold due to shivering. Rectal
(Tre) BBT was not different between trials for neither NCG (1: 37.34±0.16°C; 2: 37.35±0.27°C) nor
HCG. At exercise termination, Tre forehead sweating cessation increased (P<0.05) in trial 2
irrespective of group (1: 37.55±0.39°C; 2: 37.90±0,46°C). Tre shivering onset did not increase
(P>0.05) in trial 2 (1: 36.91±0.50°C; 2: 37.07±0,45°C). The widths of the interthreshold zone
increased (P<0.05) in trial 2 (1: 0.64±0.22°C; 2: 0.82±0.37°C) due to the increased sweating threshold
only. HCG cooled quicker (1: -l.15±0,43°C; 2: -1.00±0.50°C) than NCG participants (1: -
0.58±0.22°C; 2: -0.52±O.29°C), and tympanic (Tty) sweat thresholds were significantly (P<0.05)
decreased (1: 34.76±0.54°C; 2: 35.39±0.61°C) versus NCG (l: 35.57±0.77°C; 2: 35.89±1.04°C).
Lastly, Tre and Tty thresholds were significantly different (P

James D. Tait (1836-1907) came to Canada in 1855 from Scotland. He worked in the dry goods business until he established the James D. Tait Company in 1864. The business was first located on Ontario street and specialized in furs. The business expanded to include dry goods and dress-making. After the building was destroyed by fire, Tait established and expanded the business into the Prendergast building on the corner of St. Paul and William Streets. James D. Tait died in 1907 while on vacation in Muskoka. In 1912 upon the resignation (or removal) of Benjamin Brick and Arthur Harbour, Stanley G. Smith joins the company as a director and secretary-treasurer. 1918/1919 vice-president E.J. Dignum dies. 1919 S.J. Inksater becomes a director of the company (His stock was purchased by the J.D. Tait Co.) By the 1930s the business, still in the same location, was under the leadership of Malcolm Stobie, President, Samuel J. Inksater, Vice-President and Stanley G. Smith, Secretary-Treasurer. The James D. Tait Company Limited ceased operations on 17 August 1933. The 1935 St. Catharines city directory records John Stobie, a former manager of the James D. Tait Company, operating a dry goods business at the same location, but with one-third the size of the original store space.
