Algers Phillips,619. ORDER III. GLUCINA. CHRYSOBERYL.(Mineralogy of New-York, page 375.)To the extensive series of compound crystals figured in the Mineral-ogy of New-York, I have to add a few others. For the ability to dothis, I am indebted to Dr. Leonard, of Lansingburgh, N. Y., who hasbeen uncommonly successful in his exploration of the Greenfield local-ity. He has obtained from thence specimens of extraordinary size andbeauty. Many of them exhibit the forms which I have heretofore[Nat.
