Independently of these pseudotubular glands thevegetations now and then include preexisting glan-dular structure, w^hich is not only definable by themicroscope, but is indicated, as in fig. 3, by the di-lated ducts which traverse them. In addition to their variable consistence, color,size, shape, and transformations, these vegetationsand their containing cysts are of interest in respect to 44 CONNECTIVE TISSUE NEOPLASMS. some doubtful views tliat are entertained as to theirmode of origin and tlie relations wliicli tliey bear tothe solid connective tissue mammary growths. Paget,Bryant, and Birkett, for example, teach, in the firstplace, that they may arise indepe
