Dȳfung
Sēo dȳfung gēo ƿæs hlēapung in ƿætre, ac nū hit oft is sund under ƿætre mid sierƿunge þe giefþ lyft tō ǣðmienne under ƿætre. And þēos sierƿung oft nū hātte scuba, þe cƿōm of Nīƿengliscum "Self Contained Underwater Breathing Apparatus". And æt fruman "SCUBA" segde Americiscra gūþfroggamanna ǣðmungsierƿunga.
And sume habbaþ micle lyftfatu and se dȳfere ǣðmaþ of þǣm lyftfæte and ūt in ƿæter. And þēos sierƿunge hātaþ in Nīƿenglisce "open circuit", and hit ēac oft hātte "aqualung". And Jacques-Yves Cousteau and Gagnan macodon þone ǣrestne aqualung in gēare 1942. And mǣste hit ƿæs āna for geƿeorce oþþæt in gēare 1953 se National Geographical Magazine ƿrāt fore ƿorulde ymb Sciptogan Cousteaus geƿeorce under sǣ æt Grand Congloué īege neam Marseilles þǣr ƿæs eald scip þe sanc þenden Rōm ricsode Europam, and forþȳ sƿīðe manige ƿriton tō him tō āscianne hƿǣr man mihte bycgan aqualung. And gēo se aqualung oþþe air scuba næs sƿā man nū siehþ ƿunelīc on sǣrīmum, ac his lyftƿieldend (regulator, demand valve) ƿæs micel and behindan þæs dȳferes healse, and oft mid tƿǣm lyftfatum. And oft nū þis ealde cynn scuban hātte se tƿēgra pīpa scuba.
And sume habbaþ lȳtle oxygenfatu and se dȳfere ǣðmaþ of poccan and eft ongēan in poccan, and his līc nimþ oxygen and māra oxygen cymþ of fæte, and his līc macaþ þone carbon dioxide, and in þǣre ǣðmungsyrƿunge is fæt full þæs sodalīmes þe iteþ þisne carbon dioxide, and forþȳ se dȳfere ne macaþ (bubbles), and mæg sƿimman micle lengra under sǣ mid ǣðmungsierƿunge mid samum geƿihte. And þēs sierƿunge hātaþ eftǣþmendas and in Nīƿenglisce rebreathers oþþe closed circuit. And nū sind eftǣðmendas þe misciaþ nitrogen oþþe helium in þā ǣðmunge, sƿā hātte 'nitrox' and 'heliox' and 'trimix', tō þæs þe man mæg dȳfan dēopora þonne mid ungemiscodum oxygene.

And sƿilce dȳferas oft hātton froggamenn, for þǣm þe on hira fōtum hīe habbaþ scōs þe sind sƿā þā fēt froggan, and þēs hātton finnas. On ƿinstran sīdan siehþ man tƿēgen froggamenn þe rīdaþ in hȳðe dierne under ƿætere on rīdungfȳrramme.
