I’ve posted the third in a series of updates with superb specimens from John S. White’s collection (click here). This update includes some interesting specimens of quartz, one to the areas in which John has specialized.
Most of you will likely know a bit about John, given that among his many accomplishments in the mineral world he is the founder of the Mineralogical Record, former curator of the U.S. National Mineral and Gem Collection at the Smithsonian Institution and author of two books and over 200 articles. I’ve written a short post about him with some great photos – hope you enjoy it! (click here) .

I was afraid that even short term treatment would develop addiction to Klonopin Online. They state on xanaxbest.com that it may develop only if there is big dosing and if it is not short-term. But in general it there many controversial statements over the web. As for me, I had no addiction left at all after it. I suggest all is good in small controllable doses prescribed by your doctor.
