Though a-pyrrolidinecarboxylic acid or proline occurs widely distributed in nature, it first, became knomn to chemists as a synthetic product. Inactive proline was first synthesizedby Willstatter (Ber. 33. 1160, 1900). He condensed monosodiomalonic ester with trimethylenedibromide to form l-brompropylmalonic ester. [...]  Lire la suite

The area studied in the following notes comprises some 4 square miles, and lies immediately to the southwest of the town of Guysboro proper. The first reference to the geology of the district occurs in Dawsons Acadian Geology (Edinburgh 1855) but details are not described. [...]  Lire la suite

That certain coals are liable to spontaneous combustion has been a recognized fact for many years, but the first attempt to explain the phonomenan scientifically appears to have been made about the year 1868 by Dr. M. Richters, a noted chemist. [...]  Lire la suite

In the design of insulators, and of insulation generally, the chief problem is to distribute the potential strain evenly throughout the di-electric. Unless this is the case, the insulation will not be working at its maximum efficiency. The portion of the di-electric under the greatest strain will break down first, throwing the total voltage on the remainder of the material, so that another fortion will be over-stressed and break down, this process continuing until the punctm~e is completed. This method of failure is known as "Cascade action". [...]  Lire la suite

The Province of Quebec, almost monopolizing as it does the output of maple products of the Dominion, may be said to be the centre of the maple syrup and sugar industry, with a result that the annual, value of the products from this source, amounts to a large sum. As maple sugar sand, an inevitable by-product of this industry, deemed of no particularvalue, and consequently discarded, was considered to contain malic acid, it was thought worthy of some study. Thus the present, investigations were commenced in the spring of 1911upon the recommendation of Dr. J.F. Snell, the object being to …  Lire la suite

From the position of oxygen in the periodic table its possibility as a tetravalent or hexavalent element is apparent and the constitutional formulae of a number of compounds in which oxygen occurs have been based on this fact, as for instance hydrogen peroxide. In the following paper, however, only compounds formed by the addition of halogens and halogen hydrides to organic substances containing oxygen are considered. Friedel found that hydrochloric acid and methyl ether when mixed in molecular proportion gave a liquid of the original composition boiling at a constant temperature. [...]  Lire la suite

The development of the Phase Rule by Willard Gibbs has caused a considerable interest in the various hydrated salts and the phenomena attached to their solubilities, vapour pressures, etc. There is much information to hand with regard to such salts as calcium chloride and copper sulphate, but there is still a great deal to be learned with regard to nickel sulphate and its hydrates. For instance until quite recently the action of sunlight was supposed to decompose the normal hydrate into a lower one but this theory was refuted by Dobrosserdorf (J.Russ. Phys. Chem. Soc..= 1900. 32. 300.) [...]  Lire la suite

A study of the geology of a portion of the township of Outrement was made by the author. The area under consideration is included in the sheet of Montreal and vicinity published by the Geological Survey of Canada to accompany the report of Adams and Leroy on The Artesian and other Deep Wells on the Island of Montreal.
