The sequence of the main component of the hemoglobin of the hamster and that of the camel (Camelus ferus) is given. The sequence is obtained authomaticaJly by the sequenator using the quadrol and the propyne programme •. The sequence of the a-and (l-ehains of the hamster is com­pared with the human hemoglobin; the .sequence of the hemoglobin of the camel (Camelus ferus, Camelidae). in comparison to the llama, there are to be found in the a-chains fIVe amino acid ex­changes. in the (l-ehains are two exchanges - in (l2 and (l76 - only. The sequence (l2 in camel- the P7-glycerate contac,t - is histidine: This sequence sustains the interpretation of the high altitude res­puation of the llama as mutation (l2 His-+Asn. The amino acid sequence of the hemoglobin of Camelus ferus and Camelus dromedarius is identical.
