EBULLIOSCOPE MALLIGAND - BRASS CYLINDRICAL CAP

In 1894 business partners, and later brothers-in-law, Martin Jull and Mitchell Stewart started a vineyard in the hills overlooking Armadale where they planted several varieties of wine grapes. In 1896 visiting British lord, Sir Arthur Stepney, bought Stewarts share of the vineyard. Three years later he purchased Julls share of the vineyard and named it Derry Na Sura, which reportedly translates from Gaelic to Valley of the wine. Clement Edward Pike was the manager of Derry Na Sura vineyard between 1938 and the late 1940s. Clement Pike was born in Magill, a suburb in the foothills in eastern Adelaide, in 1899. He had come to Western Australia from South Australia where he had been a wine maker in Magill. This collection of instruments was used by Mr Pike at Derry Na Sura to test the quality and the alcohol content from the wines that they produce. In 1949 Clement took Derry Na Sura Pty Ltd to court for breach of contract which he won and was awarded 72 pounds. He then moved to East Bullsbrook were he ran another vineyard until 1954 when it is thought he returned to South Australia. He died in Margill in 1981, aged 93 years.
The Ebullioscope determines the alcoholic content of wine by heating it. Water is boiled first to observe its boiling point to compare against the wine sample. The sample of wine would be boiled next, the higher the alcoholic content of the wine the lower the boiling point.
