Hi Lynn - If the glass is purple from the liquid, it probably only is purple as high up on the bottle as the liquid contents went before they evaporated (if they did). If the entire bottle has attained a purplish coloring it is probably from exposure to daylight for those many years in the barn. Most clear glass had manganese added to make it clear. How much maganese was added to the glass mix and how long the bottle was exposed to the sun' s UV rays deteremines how dark the purple color will be. Bottle collectors call this sun-colored amethyst. Manganese was added mainly between the early 1880s and the beginning of World War I. So the bottle' s coloring may help to date it. It' s not clear you' re saying the pontil scar is - is it in the center of the bottle bottom? If there is a skull on the bottle, it is probably an indication that the contents were poisonous if ingested. I can' t think of many human medicines that were marked poisonous for internal use, but acceptable for external use. If it is a medicine, you might be right, that it' s a veterinary medicine. Keep in mind that many poisonous liquids were (and are) put in bottles, including cleaning agents, insecticides, etc. I have no clue on the Dr. C. H. Michels Company of Cleveland. Check with the Cleveland Public Library - City Directories could surely identify this company. Let us know what you find out. Good luck!
