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 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 þū mæg sēon maniga gelīcnessa sƿilcra 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 ƿeorcan in atorlyfte) healf stunde oþþe lȳtle lengre, and hit is sƿīðe unhefig, and se dȳfere miht sƿimman sƿā īeþ sƿā ēan sierƿunge. And hēr is grēat gelīcnesse and in hire be hȳþƿætre geƿeorctoga bebīedeþ. thumb|left|dȳferas æt porte

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. Man macode ǣrest þis cynn froggamannberendes in Italiam for gūðe in gēare 1939 and þā Italiscan froggamenn nemnedon hit *maiale*, þe segþ 'sƿīn', for þǣm þe him ƿǣron þā ǣrestan sƿīðe earfoþlīce to stȳrienne.
