Buffonwasmorefortunatethanhisgreatrival。NotonlyhadhetherareopportunityofexaminingayoungChimpanzeeinthelivingstate，buthebecamepossessedofanadultAsiaticman-likeApe——thefirstandthelastadultspecimenofanyoftheseanimalsbroughttoEuropeformanyyears。WiththevaluableassistanceofDaubenton，Buffongaveanexcellentdescriptionofthiscreature，which，fromitssingularproportions，hetermedthelong-armedApe，orGibbon。Itisthemodern’Hylobateslar’。
Thuswhen，in1766，Buffonwrotethefourteenthvolumeofhisgreatwork，hewaspersonallyfamiliarwiththeyoungofonekindofAfricanman-likeApe，andwiththeadultofanAsiaticspecies——whiletheOrang-UtanandtheMandrillofSmithwereknowntohimbyreport。
Furthermore，theAbbePrevosthadtranslatedagooddealofPurchas’
PilgrimsintoFrench，inhis’HistoiregeneraledesVoyages’（1748），andthereBuffonfoundaversionofAndrewBattell’saccountofthePongoandtheEngeco。AllthesedataBuffonattemptstoweldtogetherintoharmonyinhischapterentitled"LesOrang-outangsoulePongoetleJocko。"Tothistitlethefollowingnoteisappended：——

"Jocko，Enjocko，nomdecetanimalaCongoquenousavonsadopte。’En’

ThusitwasthatAndrewBattell’s"Engeco"becamemetamorphosedinto"Jocko，"and，inthelattershape，wasspreadallovertheworld，inconsequenceoftheextensivepopularityofBuffon’sworks。TheAbbePrevostandBuffonbetweenthem，however，didagooddealmoredisfigurementtoBattell’ssoberaccountthan’cuttingoffanarticle。’
ThusBattell’sstatementthatthePongos"cannotspeake，andhavenounderstandingmorethanabeast，"isrenderedbyBuffon"qu’ilnepeutparler’quoiqu’ilaitplusd’entendementquelesautresanimaux’"；andagain，Purchas’affirmation，"Hetoldmeinconferencewithhim，thatoneofthesePongostookeanegroboyofhiswhichlivedamonethwiththem，"standsintheFrenchversion，"unpongoluienlevaunpetitnegrequipassaun’an’entierdanslasocietedecesanimaux。"
AfterquotingtheaccountofthegreatPongo，Buffonjustlyremarks，thatallthe’Jockos’and’Orangs’hithertobroughttoEuropewereyoung；andhesuggeststhat，intheiradultcondition，theymightbeasbigasthePongoor’greatOrang’；sothat，provisionally，heregardedtheJockos，Orangs，andPongosasallofonespecies。Andperhapsthiswasasmuchasthestateofknowledgeatthetimewarranted。ButhowitcameaboutthatBuffonfailedtoperceivethesimilarityofSmith’s’Mandrill’tohisown’Jocko，’andconfoundedtheformerwithsototallydifferentacreatureastheblue-facedBaboon，isnotsoeasilyintelligible。
TwentyyearslaterBuffonchangedhisopinion，*andexpressedhisbeliefthattheOrangsconstitutedagenuswithtwospecies，——alargeone，thePongoofBattell，andasmallone，theJocko：thatthesmallone（Jocko）istheEastIndianOrang；andthattheyounganimalsfromAfrica，observedbyhimselfandTulpius，aresimplyyoungPongos。

ThesesketcheshavebeenreproducedbyFischerandbyLucae，andbeardate1783，Soemmeringhavingreceivedthemin1784。HadeitherofVonWurmb’sspecimensreachedHolland，theywouldhardlyhavebeenunknownatthistimetoCamper，who，however，goesontosay——"Itappearsthatsincethis，somemoreofthesemonstershavebeencaptured，foranentireskeleton，verybadlysetup，whichhadbeensenttotheMuseumofthePrinceofOrange，andwhichIsawonlyonthe27thofJune，1784，wasmorethanfourfeethigh。Iexaminedthisskeletonagainonthe19thDecember，1785，afterithadbeenexcellentlyputtorightsbytheingeniousOnymus。"

Eventually，inaccordancewiththeusualmaraudinghabitsoftheRevolutionaryarmies，the’Pongo’skeletonwascarriedawayfromHollandintoFrance，andnoticesofit，expresslyintendedtodemonstrateitsentiredistinctnessfromtheOranganditsaffinitywiththebaboons，weregiven，in1798，byGeoffroySt。HilaireandCuvier。
