Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Passage: I whakahaerehia e Horace Wells te whakaaturanga tuatahi a te iwi mo te anesthetic inhalation i te Massachusetts General Hospital i Boston i te 1845. Heoi anō, kāore i tika te hoatu o te waikura nitrous, ā, i karanga te tūroro i te mamae. I te 16 o Oketopa 1846, ko te taote niho o Boston a William Thomas Green Morton i whakaatu angitu i te whakamahi i te diethyl ether ki nga akonga rongoa i te waahi kotahi. I karangatia a Morton, e kore nei e mōhio ki nga mahi o mua a Long, ki te Massachusetts General Hospital hei whakaatu i tana tikanga hou mo te pokanga kore mamae. I muri i te whakamāoritanga a Morton, ka tangohia e te tohunga taihara a John Collins Warren tētahi pukupuku mai i te kaki o Edward Gilbert Abbott. I puta tēnei i roto i te whare whakawātea e kiia nei ko te Ether Dome. I miharo a Warren, te tangata ruarua i mua, a ka mea, "E nga rangatira, ehara tenei i te tinihanga". I roto i te reta ki a Morton i muri tata mai, ka tono te taakuta me te kaituhi a Oliver Wendell Holmes, Sr. ki te whakaingoa i te whenua i whakaputaina ko te "anesthesia", me te tikanga he "anesthetic". I te tuatahi ka ngana a Morton ki te huna i te ahuatanga o tana taonga anesthetic, e kii ana ko Letheon. I riro i a ia he mana ā-U.S. mō tana matū, engari i tere te horapa o te rongo o te rongo angitu i te mutunga o te tau 1846. Ko nga tohunga whakaahuru rongonui i Uropi, tae atu ki a Liston, Dieffenbach, Pirogov, me Syme, i tere te whakahaere i te maha o nga mahi ki te ether. I whakatenatena e te tākuta i whānau mai i Amerika, a Boott, te tākuta niho o Rānana, a James Robinson, ki te whakatinana i tētahi tukanga niho ki tētahi Miss Lonsdale. Ko te take tuatahi tēnei o tētahi kaituku mahi-tūnga. I taua rā anō, i te 19 o Tihema 1846, i Dumfries Royal Infirmary, Scotland, i whakamahia e tētahi Tākuta Scott te ether mō tētahi tukanga pokanga. Ko te whakamahinga tuatahi o te whakamate i te Hauauru ki te Tonga i Launceston, Tasmania, i taua tau ano. Ko nga ngoikoretanga o te ether penei i te pukupuku nui me te mura o te pupuhi i arahi ki te whakakapi i Ingarangi me te chloroform. I kitea i te 1831 e te taakuta Amerikana a Samuel Guthrie (1782<unk>1848), me te motuhake i etahi marama i muri mai e te Frenchman Eugène Soubeiran (1797<unk>1859) me Justus von...

E nga rangatira, ehara tenei i te tinihanga
