Todd and Bowman, like Rossignol, adopt the views of Mr. Rainey, and teach that the air-cells have no epithelium of any kind. The adjoined is the illustration of the epithelium given by Schroeder Van der Kolk in Adriani's Ultimate cells of the human lung, showing the trabi- cular framework formed by the elastic fibres of the walls, and the hyaline pavement epithelium which lines the interior of the air-cells. (After Schroeder Van der Kolk, quoted by Adriani.) By this distinguished observer it is repre- sented under the character of transparent pavement epithelium, the cells of which are * In suggesting the word hyaline as a distinctive epithet for this variety of epithelium, I do not wish to be understood as denying, in its component scales, the existence of every form of visible element. 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.
