Buffonwasmorefortunatethanhisgreatrival。NotonlyhadhetherareopportunityofexaminingayoungChimpanzeeinthelivingstate，buthebecamepossessedofanadultAsiaticman-likeApe——thefirstandthelastadultspecimenofanyoftheseanimalsbroughttoEuropeformanyyears。WiththevaluableassistanceofDaubenton，Buffongaveanexcellentdescriptionofthiscreature，which，fromitssingularproportions，hetermedthelong-armedApe，orGibbon。Itisthemodern’Hylobateslar’。
Thuswhen，in1766，Buffonwrotethefourteenthvolumeofhisgreatwork，hewaspersonallyfamiliarwiththeyoungofonekindofAfricanman-likeApe，andwiththeadultofanAsiaticspecies——whiletheOrang-UtanandtheMandrillofSmithwereknowntohimbyreport。

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。
