When Jane Austen wrote in January 1801 that ‘Mrs Powlett was at once expensively and nakedly dressed’, the fashion for muslin dresses had existed for some eighteen years. This article examines the crucial period between 1779 and 1784 when the muslin garment, which became known as the chemise à la reine, was developed and refined. Originating in the French West Indies, the gaulle was the ‘colonial livery’ worn by the wives of the white elite, the ‘grands blancs’, and first appeared as a costume in a ballet performed in Paris in 1779. The version worn by Queen Marie Antoinette in Vigée Le Brun's controversial portrait of 1783 provoked, according to the Baron de Frénilly, ‘a revolution in dress’ which eventually destabilized society. The article focuses on the role played by Saint-Domingue, France's most valuable overseas possession, in the transference of the gaulle from colonial to metropolitan fashion, and how the colony became one of the major providers of unprocessed cotton to the French cotton industry.

<p>Penelitian ini bertujuan untuk menentukan senyawa organik khususnya organic karbon terlarut (DOC) dari dua spesies daun tumbuhan (<em>wandoo eucalyptus </em>and <em>pinus radiate, conifer</em>) yang larut dalam air selama periode 5 bulan leaching eksperimen. Kecepatan melarutnya senyawa organic ditentukan secara kuantitatif dan kualitatif menggunakan kombinasi dari beberapa teknik diantaranya Total Organic Carbon (TOC) analyser, Ultraviolet-Visible (UV-VIS) spektrokopi dan pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS).</p><p>Hasil analisis DOC dan UV menunjukkan peningkatan yang tajam dari kelarutan senyawa organic di awal periode pengamatan yang selanjutnya berkurang seiring dengan waktu secara eksponensial. Jumlah relatif senyawa organic yang terlarut tergantung pada luas permukaan, aktifitas mikrobiologi dan jenis sampel tumbuhan (segar atau kering) yang digunakan. Fluktuasi profil DOC dan UV<sub>254</sub> disebabkan oleh aktifitas mikrobiologi. Diperoleh bahwa daun kering lebih mudah terdegradasi menghasilkan senyawa organic dalam air dibandingkan dengan daun segar. Hasil pyrolysis secara umum menunjukkan bahwa senyawa hidrokarbon aromatic dan fenol (dan turunannya) lebih banyak ditemukan pada residue sampel setelah proses leaching kemungkinan karena adanya senyawa lignin atau aktifitas humifikasi mikrobiologi membuktikan bahwa senyawa-senyawa tersebut merupakan komponen penting dalam proses karakterisasi DOC.</p>
