place with string. Flow some resin or Fluxite along theseam and close the seam with solder. On no account use spirits of salts as a flux. While still on the wooden former, the container-body isto be wound with 30 S.W.G. piano wire, the pitch of the spiralsolutions being -*„- in. The reason for such binding is self- evident—it prevents the container bursting under pressure. Having finished the winding (which is soldered to the foilat every revolution, and is, moreover, pulled quite tightly round it) and before withdrawing the former, one of the half-balls may be soldered to the cylindrical shell—of course, tinning the faces in contact as before. The airtight tap andvalve should be fixed to the half-balls prior to the assembly of the latter to the cylinder. To the inside of one of the half-balls (the final one to beattached) a 26 S.W.G. tension wire is soldered. Withdrawingthe wooden former, the tension wire should be passed through the container and its end threaded through a hole previouslyvdrilled in the half-ball first attached. Apply a little tension, working the loose half-ball into position inside the cylinder,and while still pulling on it solder it into the hole. Now solder the second half-ball into place (remembering tohave tinned the surfaces before fixing them), letting the solder flow well into the joint. Test the container for leaks in a bath of paraffin. H H H H LEGAL INTELLIGENCE The Aeronautical Institute AT BOW Street Police Court on November 6th, Sir ChartresBiron concluded the hearing of the summons against Lucien Blin Desbleds and Colonel Frederick Natusch Maude, C.B.,for carrying on business as the Aeronautical Institute of Great Britain at Lincoln's Inn Fields, without having furnishedparticulars as required by the Registration of Business Names Act, 1916. In announcing his decision, the Magistrate said that the only question he had to determine was whether or not the institute had been run for profit. It had been suggested that the shareholders' interests were not protected, but none of the shareholders had ever objected, and if they had asked for a meeting one would have been held- There was very little evidence for the prosecution that the institute had been run for profit, and he was now satisfied that this had not been the object. He dismissed the summons, and ordered the Board of Trade to pay each of the defendants £$ 5s. costs. Mr. Burrows, who appeared for the Board of Trade, protested against an order for costs. The Magistrate remarked that if the Board of Trade choseto take proceedings and failed they must pay the same as everyone else.

The reason given for leaving Holland is failure to conclude contracts with the Dutch Government necessary to enable him to keep his new Dutch aeroplane works running, the Dutch Government preferring to give orders to British firms for a number of De Havilland and Avro aeroplanes.
