The Elements of Materia Medica

Pereira, Jonathan
This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1839 edition. Excerpt: ...History.--Iodine and potassium are contained in sea-water, as well as in sea-weeds, but whether the iodine is in combination with potassium or with some other metal (sodium or magnesium) it is impossible to say with certainty. Preparation.--There are two principal methods of procuring this salt. (a.) Process of the Pharmacopeia.--This consists in adding two ounces of iron filings to six ounces of iodine mixed with four pints of water, stirring them frequently with a spatula for half an hour. Apply a gentle heat, and, when a greenish colour appears, add four ounces of carbonate of potash, first dissolved in two pints of water, and strain. Wash the residue with two pints of boiling distilled water, and again strain. Let the mixed liquor be evaporated, that crystals may be formed. The theory of this process is as follows:--One equivalent or 126 parts of iodine combine with one equivalent or 28 parts of iron. The resulting iodide of iron is decomposed by one equivalent or 70 parts of carbonate of potash, by which one equivalent or 160 parts of iodide of potassium and one equivalent or 58 parts of protocarbonate of iron are procured. 1 eq.

Dr. Turner's process.--This is the simplest, and I believe the most eligible method. It consists in adding to a hot solution of pure potash as much iodine as the liquid will dissolve, by which means a reddishbrown fluid is obtained. Then pass hydrosulphuric acid through the liquid until it becomes colourless. Apply a gentle heat, to expel any excess of the acid; filter to get rid of the free sulphur, and exactly neutralize...

Sets and Numbers for the Very Young

Irving Adler,Ruth Adler
Sets and Numbers for the Very Young This boy has two cars with which he hears, One nose that he blows. Two lips with which he sips. Two hands on which he sometimes stands. This girl is on her way to school. Her clothes are clean and neat. She has two hats upon her head. And one shoe on her feet. Ears, lips, hands, feet, fingers, hats, shoes-all come in sets. Many things come in sets. They may be sets of ten or two, one or three or a thousand. A number tells how many. With sets and numbers you learn about adding and taking away, about matching and comparing, about putting together and taking apart, about left and right, about before and after, about counting. Open this book and begin to see all that you can learn from sets and numbers. About the Authors IRVING ADLER, whose book The New Mathematics was the first on its subject for the adult general reader, wrote this book for very young children with his wife Ruth. The holder of a Ph.D. in pure mathematics from Columbia University, Irving Adler was an instructor in math at Columbia as well as at Bennington College and was formerly head of the mathematics department of a New York City public high school. His wife Ruth taught mathematics in public schools In the Greater New York area. Ruth Adler died in 1968, one year prior to the publication of this book by The John Day Company. Irving Adler had 87 titles to his name when he passed away in 2012, at almost 100 years of age. His books were published in 31 countries, in 19 different languages. About the Illustrator PEGGY ADLER is the daughter of Irving and Ruth Adler and author of BearManor's Peggy's Puzzles - Volume One (2023) and Pallenberg Wonder Bears - From The Beginning (2022). Previously, she authored the 2019, award winning pictorial history, Images of America CLINTON (Arcadia) and five books for New York City publishers (The John Day Company & Franklin Watts). Additionally, Ms Adler illustrated two dozen books and provided art for the Bronx Zoo; the Humane Society of the United States; Little, Brown & Company and many others. She also coordinated the 1969 World Premiere of Butch Cassidy and the Sundance Kid for 20th Century Fox and in 1991, served as a consultant to the U.S. House of Representatives' October Surprise Task Force. She's a Marquis Who's Who Albert Nelson Marquis Lifetime Achievement honoree; a 2001 recipient of the Association of Former Intelligence Officers' General Richard G. Stilwell Award; a former police commissioner; and currently chairs the Town of Clinton, Connecticut's Historic District Commission.
