Bach turn of the wire lies in a plane passing through the axis of the ring, the wires being wound as closely as possible on the inner surface of the ring and uniformly spaced on the outer surface. Taking account of the magnetic field within the space occupied by the wire as well as the space within the marble core, Prof. Frohlich obtained the following expression for the self-inductance of the coil :","PeriodicalId":227231,"journal":{"name":"Bulletin of the Bureau of Standards","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1907-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131389093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The equilibrium between cadmium amalgam and cadmium sul phate was first studied. Saturated solutions of the latter were shaken up in air, nitrogen, hydrogen, and in vacuo with cadmium amalgam, but in no case did the electromotive force of cells set up with the treated and untreated solutions differ more than 10 microvolts, even though the samples shaken in the presence of air had become cloudy from the formation of an excess of basic cadmium sulphate. The equilibrium of the system mercury, mercurous sulphate, cad mium sulphate, and of the corresponding system of the Clark cell was then studied in special cells, so constructed that the above materials could be rotated and the effect determined without open ing the cell. This consisted of a tube about 2 cm in diameter and 1 2 cm long, provided at the lower end with a small bulb into which a platinum wire was sealed. The bulb was connected to the main tube by a narrow neck, so that, with sufficient mercury in the cell, the plati num terminal was not in contact with the solution, even during rotation.","PeriodicalId":227231,"journal":{"name":"Bulletin of the Bureau of Standards","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1907-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132974793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
