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 ǣðmungsyrwunge is fæt full þæs sodalīmes þe iteþ þisne carbon dioxide, and forþȳ se dȳfere ne macaþ (bubbles), and mæg swimman micle lengra under sǣ mid ǣðmungsierwunge mid samum gewihte. And þēs sierwunge hātaþ eftǣþmendas and in Nīwum Englisce rebreathers oþþe closed circuit. And nū sind eftǣðmendas þe misciaþ nitrogen oþþe helium in þā ǣðmunge, swā hātte 'nitrox' and 'heliox' and 'trimix', tō þæs þe man mæg dȳfan dēopora þonne mid ungemiscodum oxygene. And þū mæg sēon maniga gelīcnessa swilcra hēr .
Hēr is lȳtel āstȳriende biliþ dȳferes mid þǣm lȳtlan oxygeneftǣðmende Salvus þe Siebe Gorman gēo macode in Lundene, and mid him man mihte dȳfan (oþþe weorcan in atorlyfte) healf stunde oþþe lȳtle lengre, and hit is swīðe unhefig, and se dȳfere miht swimman swā īeþ swā ēan sierwunge. And hēr is grēat gelīcnesse ond in hire be hȳþwætre geweorctoga bebīedeþ.
And swilce dȳferas oft hātton froggamenn, for þǣm þe on hira fōtum hīe habbaþ scōs þe sind swā þā fēt froggan, and þēs hātton finnas.

Hīe habbaþ þone Bryttiscan eftǣðmend CDBA þe Siebe Gorman macode, þe segþ in Nīwenglisce "Clearance Diver's Breathing Apparatus", and in Brytenes scipfyrde clearance diver is scipfyrdisc dȳfere þe dȳfeþ to weorcanne and ne tō feohtanne.
Man siehþ twēgen froggamenn mid þǣm Russiscan eftǣðmende IDA71, and ān hira rīdeþ þone Russiscan dȳfereberend Protei 5. And hēr sind þrēo dȳferas mid þǣm IDA71.
