The word should be accepted in a com- parative sense, as signifying that their nuclei and granules are less declared than those of any other description of epithelium. f This figure is thus described by Adriani: — " Alveoli constant membrana subtilissima structure carente, qua?, autem membrana mucosa tegitur epi- thelio pavimentoso (plaat epithelium') admodum pel- lueiilo, in quo potissimum ope acidi acetici nuclei conspiciuntur; propter singularem autem pelluci- ditatem srepe difficile est, illud epithelium rite dis- tiuguere; vid. fig. 12. nostram, ubi ad alveolorum parietes conspicitur. Cellulte conica? ciliatie qua? in bronchiolis minutis adhuc conspiciuntur, in alveolis penitus deficiunt; hajc membrana cum epithelio pavimentoso obtegit vasa sanguifera per alveolorum parietes ducta ; propter singularem tenuitatem im- bibitio atqne absorptio per hanc membranulam facillime pcrfici posse facile ;—Op. cit. p. 61. furnished with a nucleus and minute granules They are adjusted accurately, as a single la\er, edge to edge.
