ItwillbeseenthatWiseinAmerica,contrarytothepracticeofGreeninourowncountry,hadastrongattachmenttotheantiquemodeofinflationwithhydrogenpreparedbythevitriolicprocess;andhisballoonswerespeciallymadeandvarnishedfortheuseofthisgas。Theadvantagewhichhethusboughtattheexpenseofmuchtroubleandtheprovidingofcumbersomeequipmentwasobviousenough,andmaybewellexpressedbyaformulawhichholdsgoodto—day,namely,thatwhereas1,000cubicfeetofhydrogeniscapableoflifting7

ItwouldevenseemfromastatementofMr。MonckMasonthatthevalueofcokeinhisdaylargelycompensatedforthecostofproducingcoalgas,sothatinalargenumberofGreen’sascentsnochargewhateverwasmadeforgasbythecompaniesthatsuppliedhim。
