Dear Sir: I wrote you some time ago stating that I should be pleased to have Mr. Schuchert at his earliest convenience send me collection of fossils as you could afford to spare in exchange for part of meteorite. As the fossils have not come I write this simply to remind you in case the former letter has for some cause not reached you Sincerely O. C. Charlto

National Museum discussing how to slice the samples.Baylor University O. C. Charlton, Department of Natural Science Waco, Texas, April 22, 1901 Mr. Geo. P. Merrill U. S. National Museum, Washington, D. C. Dear Sir: I today express you one of the masses of the Fayette County Meteorite which I have had about one year. Please to examine it carefully and slice it in the way which will make the resulting slices of most value. I suggest four slices which will require three cuttings each slice to show a goodly portion of the weathered surface. Keep it yourself and slice thick cuts to repay you for your work. Perhaps you might take a little more than enough to repay you for your trouble and send me as compensation a small piece of some other meteorite of a different kind. All these matters I entrust to your judgement and fairness [unintelligible] that will do what is best. I prepay express age. I hope this stone will reach you in time for your attention before you go away. My delays in regard to it have not been altogether inexcusable. Beside full college work I have been so situated that extra duties were always demanding my time. Sincerely O. C. Charlton

Charlton, Department of Natural Science. Waco, Texas, May 23 1901 Mr. George P. Merrill U. S. National Museum Washington, D. C. Dear Sir: Yours of recent date proposing that Mr. Schuchert select fossils from his department in return for yours part of the meteorite came promptly to hand as did the two pieces of the meteorite. With the latter I wish to thank you for the satisfactory result of your cutting. As to the possibles, I shall be please to have the collection made up and shipped at your earlier convenience, I shall have the selection entirely to Mr. Schuchert, requesting only that rather pull details as to locality we be stated. Please extend to him my assurance of strong regard and that I recall often and with pleasure his companionship in Wyoming it seems that the “U. P. Fossil Field Expedition” was to say the least a stimulus to considerable independent work in Wyoming since that picturesque train up Geologists and scientists of various degrees enlivened its solitude. Permit me to say to both of you that if occasion permits I shall be glad at any time to be of service to you. Sincerely O. C. Charlto

Correspondence from O. C. Charlton to George P. Merrill, May 7, 1901
No full textHandwritten letter from O. C. Charlton with Baylor University in correspondence with George P. Merrill from the U. S. National Museum discussing a growing collection.Baylor University O. C. Charlton, Department of Biology & Geology. Ansd. May 13, 1901. Waco, Texas, May 7, 1901 Mr. George P. Merrill U. S. Nat. Museum, Washington D. C. Dear Sir: Yours of May 3 at hand yesterday. It reached me while I am somewhat sick and off duty. I do not readily see clearly what I should write you in regard to the cutting of the meteorite. We already have the school collection of nearly 60 minerals from your museum and, also, the collection of 130 to 160 stones, I should not care to have these drypreated to any material extent. It, however, occurs to me that you should so cut the meteorites (1) that you may keep half of it. (2) What am half be cut into two pieces of unequal size the large piece two or three times the size of the smaller, the smaller piece being so cut that it may have thin places where smaller pieces may be easily knocked off. Better that this would be a thin slice which I myself could divide and (3) What for the present you consider yourself indebted to me and when you can let me have mineral for fossils in satisfaction of the obligation. Perhaps you may have some things just to very liking. A young small becomes curator of one museum, Mr. James J. Carroll who will I think be in your museum for a trip this summer and maybe I could have them camper with you then if not you can write me what one be and are able. So cut it as you suggest and one will have no difficulty I think getting it arranged all right. Yours O. C. Charlto
Correspondence from O. C. Charlton to George P. Merrill, September 30, 1899
No full textHandwritten letter from O. C. Charlton with Baylor University in correspondence with George P. Merrill from the U. S. National Museum regarding the Fayette County, Texas meteorite and Mart stone.Baylor University Waco, Texas. Sept 30 1899 The National Museum Smithsonian Institution Section of Meteorites Gentlemen: I have recently purchased for Baylor University of Mr. Henry T. Vaughan, Mart, McLenanan Co the meteorite which he sent to you for examination last July. You will I doubt not receive notice to this effect from him before this reached you. I know little of meteorites or the methods of handling them to the best advantage. It occurs to me that it weights be of advantage to your institution and I think of advantage to our college to have two or three things done with it. First. Can you conveniently photograph it in possibly two positions duplicating your negatives and letting me pay you for one of each. Second. Would it materially impair its value for you to cut off a moderately sized piece from one end. The small piece to be retained by you as a sample and for use in chemical analysis of the iron. The cut surface on the large piece to be polished so as to exhibit any peculiarities of structure which can be exhibited by polishing. Third. I should like copy of any statement you may anytime prepare for report or publication regarding it. In mentioning the second point I place full reliance upon your judgement in the matter largely on account of its local interest. I have wished our Baylor University to leave the meteorite but in securing it I do not wish to detract in any way from its value as a sample for scientific examination. I feel that to have a plane surface on one side polished will compensate us for such small part as you would need for physical and chemical study. Yet I would like it photographed accurately before its original appearance is modified. There is reason to believe that it was seen by with a number of people the night of its fall. I shall secure what information I can regarding this and if I find that it indicates that it was seen I will transmit the information to you if you wish it. Yours O. C. Charlton.

Enhanced light extraction by photonic quasi-crystals in GaN blue LEDs
No full textThe far-field profile of photonic quasi-crystal patterned and unpatterned LEDs, fabricated from commercial epitaxial substrates by electron beam lithography, has been measured prior to lapping and dicing. Emission enhancements reach a maximum of 62%, and are strongly dependent on the filling factor. Qualitative agreement is achieved between 2-D finite-difference time-domain calculations and the experimental data
