unde error medius in valore lateris Falkenberg-Breithorn metuendus — 0,2886m 
metris, (ubi m error medius in directionibus observatis metuendus, et quidem 
in minutis secundis expressus), adeoque, si valorem ipsius m supra erutum 
adoptamus, 
— 0 m l209 
Ceterum inspectio systematis triangulorum sponte docet, punctum Hau- 
selberg omnino ex illo elidi potuisse, incolumi manente nexu inter latera 
Wilsede-Wulfsode atque Falkenberg-Breithorn. Sed a bona methodo abhor
