Iodine is an essential trace element for life, the heaviest element commonly needed by living organisms. In medicine, potassium iodide is usually used to treat acute thyrotoxicosis. Hyperthyroidism, an overactive thyroid, is a condition in which the thyroid gland produces and secretes excessive amounts of the free (not protein bound, and circulating in the blood) thyroid hormones, This is the opposite of hypothyroidism ('sluggish thyroid'), which is their reduced production and secretion. Graves' disease is the most common cause of hyperthyroidism. Iodine's main role in animal biology is as a constituent of the thyroid hormones thyroxine If there is a deficiency of dietary iodine, the thyroid will not be able to make thyroid hormone. The lack of thyroid hormone will lead to decreased negative feedback on the pituitary, leading to increased production of thyroid-stimulating hormone, which causes the thyroid to enlarge (the resulting medical condition is called endemic colloid goitre This has the effect of increasing the thyroid's ability to trap more iodide, compensating for the iodine deficiency and allowing it to produce adequate amounts of thyroid hormone. The thyroid hormones are essential to proper development and differentiation of all cells of the human body. These hormones also regulate protein, fat, and carbohydrate metabolism, affecting how human cells use energetic compounds. They also stimulate vitamin metabolism. Natural sources of iodine include sea life, such as kelp and certain seafood, as well as plants grown on iodine-rich soil. Iodized salt is fortified with iodine. Elemental iodine is used as a disinfectant in various forms. It is a wound cleaner and Iodine also acts as an expectorant of mucous from the common cold and other respiratory ailments. Iodine is a common aid for skin conditions, such as acne, ..A brown glass triangular shaped bottle with a plastic screw top lid that contained IodineFront Label : SANA / TINCTURE WEAK (2 1/2 % ) / IODINE / POISON / ANTISEPTIC COUNTER / IRRITANT ETC. / THE SANAX CO. / 5 BRUNSWICK STREET FITZROY / TEL.

Sandra Pullman visited the Melbourne City Council Exhibition, 'Melbourne Parks and Gardens Through the Magic Lantern' in November 2012. Lex Nieboer, former Burnley student graduating in 1975, found a large number of glass lantern slides in a store room and took them home as he was concerned they would be thrown out. His family has a long tradition of being involved in photography, so he understood the value of the slides. He donated the ones that were of Melbourne City Parks and Gardens to the Council and they used them in their exhibition. Sandra contacted Lex and arranged with Jane Wilson (Archivist) to visit Lex on 12 April, 2013 at Wilson Botanic Park, Berwick where he works. After Lex showed them the slides, he, very generously, donated approximately 300 slides back to the Burnley Archives. There was already a collection of almost 100 glass slides in the Archives. They were in a wooden box containing glass lantern slides with label on outside, "Slides of Horticultural Objects and Views." Inside lid is handwritten, "Mr Bailey Botanic Gardens Adelaide." (John Frederick Bailey, Director Adelaide Botanic Gardens 1917-1932.) and, "Mr Isaac 9 pla? 2 ficifolia." (Probably Mr Isaacs Mayor of Adelaide 1917.) Also, "Purchased from Estate of Reeves Late Malvern Gardens, AWJ." (F.L. Reeves, Malvern Council's Park Curator in the 1920's died in 1933. AWJ, A.W. Jessep, Principal Burnley Horticultural College 1926-1941.) These were numbers 61-85 "History of the Rose." Geoff Olive, former Staff member, remembered taking a number of glass slides to a photographic processor to have 35mm slides made from them. 60 of these are also in this collection. Also see B10.0057 for Melbourne City Council collection and, 11.0039, 12.0033 for photograph prints of lantern slides lost to the collection.Collection of approximately 400 glass lantern slides used for teaching at Burnley Horticultural College during the first half of the twentieth century. Some were made specifically for Burnley. Some images would not upload. The images include: overseas views of gardens, historical sites and geographical features (some hand coloured from Japan); a series of hand coloured images of roses with notes for teaching the history of the rose; school gardens of the early 1900's; fruit and vegetables; miscellaneous horticulltural; Australian native plants; cells; 'Living Races'; plants, trees and grasses; parasites, organisms and fungal diseases; miscellaneous horticultural scenes; parks; cattle; agricultural data.sandra pullman, lex nieboer, melbourne city council exhibition through the magic lantern, john frederick bailey, mr isaacs, f l reeves, a w jessep, history of the rose, plants, trees, diseases
