Eyinom nyinaa nti, sɛ yɛreka nnipa a wɔtenaa afe 1701 kosi 1800 a, ɔda mu fua.”—Frederic Harrison, onimdefo.

Ná Joseph Priestley de nyansahu gyigye n’ani kɛkɛ. Afe 1765 mu, ɔne Amerikani nyansahufo Benjamin Franklin hyiae. Ɛno akyi na Priestley fii ase hwehwɛɛ sɛnea anyinam ahoɔden yɛ adwuma. Nea ohu de too gua no yɛɛ ne mfɛfo nyansahufo nwonwa paa, enti afe a edi hɔ no, wɔbɔɔ n’aba so ma ɔkɔkaa Royal Society of London kuw no ho.
Afei Priestley de n’adwene kɔɔ mframa so. Anni da bi na ohui sɛ sɛɛ yɛwɔ mframa ahorow ahorow. Ebi ne ammonia ne nitrous oxide a ebinom frɛ no laughing gas no. Ɔde mframa a yɛfrɛ no carbon dioxide fraa nsuo a yɛnom mu mpo; ɛno na ɛdede mu a yenyaa nsuo a carbon wom.
Afe 1774 mu a Priestley reyɛ nhwehwɛmu wɔ England anafo no, ohuu mframa bi a ɛma kyɛnerɛ hyerɛn kɛse. Akyiri yi ɔde saa mframa no kakra (60 ml) guu glass mu na ɔde akura hyɛɛ mu.

Joseph Priestley huu mframa a yɛfrɛ no oxygen * na ɔfaa no sɛ mframa biara kɛkɛ—mframa a entumi nhye adeɛ. Nanso na ɛnyɛ nokware. Ɛno mpo nnipa pii fa no sɛ nneɛma a ohui nyinaa, “ɛno ne ade kɛseɛ paa a ɛwom.”
ƆHWEHWƐƐ NYAMESOM MU
Sɛnea Priestley nyaa gyidi sɛ ebinom de wɔn nsusuwii akata nyansahu mu nokwasɛm so no, saa nso na ohui sɛ ebinom de atetesɛm ne mmara-mmara bi akata nyamesom mu nokwasɛm so.

Afei nso asɛm a ɛwɔ Bible mu sɛ Yesu tenaa soro ansa na ɔreba asase so no, ná onnye nni.
“Sɛ nokware a obi behu na ɛkyerɛ sɛ ɔyɛ nyansahufo de a, ɛnde na Priestley yɛ nyansahufo paa.”—Katherine Cullen, nyansahufo
Nanso nkyerɛkyerɛ bɔne a na ɛkɔ so wɔ asɔre akɛse mu saa bere no ne nnɛ nyinaa no, Priestley bɔ gui. Ɔkyerɛw sɛ, Yesu ne n’asuafo no kyerɛkyerɛɛ nokware no, nanso akyiri yi na ebinom de nkyerɛkyerɛ bi a ɛnyɛ nokware fraa mu. Ebi ne Baasakoro, onipa kra a ebinom kyerɛ sɛ enwu da, ne ahonisom. Eyinom nyinaa Bible bɔ gu.
