Mr. Lutz Neweklowsky, Drais-1, 76135 Karlsruhe, Germany, tel/fax 0049 721 841 095, sent me a letter (posted 20th March 2000) with the following interesting claim:

"As it is known, there exists an old record of O. T. Bláthy from the year 1889 with rem mate in 257 without "obtrusive pieces" (opinion of J.
