154 Note: The diatomaceous deposit, so often called 'Bermuda' or 'Bermuda tripoli,' especially by foreign writers, is in reality the Miocene stratum extending for miles along the Patuxent River near the village of Nottingham, Md. The author is perfectly familiar with the location, having made large collections there. The mistake in the name is due to the fact that Prof. Bailey received material from Mr. Tuomey marked 'Bermuda Hundred,' which is located near Petersburg, Va. Attempts have been made to find material there and while there is an earth containing Miocene diatoms at Petersburg, it does not exactly correspond to the material sent to Ehrenberg by Bailey, who was in doubt as to the locality. The Bermuda Islands are of coral formation and have no deposits of diatomaceous earth. ........Boyer, 1916, p. 18 I have not determined how many of the samples in this Collection should be subject to Boyer's concern over the location of "Bermuda." I have presented Boyer's note solely to present the "Bermuda problem;" I cannot attest to the correctness of Boyer's conclusions. A further examination of the problem should include at least Bailey (1845), Stodder (1874), Johnston (1874), Sullivant (1875), and Boyer (1900, p. 690, footnote 4; 1916, p. 18).
