THE MAMMALIAN ALVEOLINGUAL SALIVARY AREA, 

 WITH SPECIAL REFERENCE TO THE DEVELOP- 

 MENT OF THE GREATER SUBLINGUAL GLAND 

 OF THE PIG, TOGETHER WITH A REVIEW OF THE 

 LITERATURE 



By H. von W. Schulte 



Of the glands of the alveolingual region the submaxillary has been 

 most successfully investigated, and alone has received a consistent 

 treatment in the Hterature. With regard to the others much confusion 

 has obtained both in respect to their number and as to their mutual 

 relations, the result in large part of the difficulty of the problems in- 

 volved, but complicated by the misfortune of an uncritical and incon- 

 sistent nomenclature. The relations of these glands in man are 

 especially intricate, owing, first, to the compression and consolidation 

 of the several elements in correlation with the reduction of the man- 

 dible, and, second, to the inconstancy of the Barthohnian element, so 

 that here the analysis of the gland complex, on anatomical grounds, is 

 rendered almost impossible of successful accomplishment. The 

 preoccupation of anatomists with this form, however justified by practi- 

 cal considerations, has served to retard the solution of these problems, 

 by diverting attention from types of easier analysis, and depriving of its 

 due weight evidence derived from the study of the lower mammals. 

 The unsatisfactory state of our knowledge of human conditions is illus- 

 trated by the BNA, Glandida sublingualis , Ductus sublingualis major, 

 Ductus sublingual.es minores. Here the concept "gland" itself is 

 vague, and the error is made of taking the secondary coaptation of the 

 connective tissue as the criterion of glandular entity, irrespective 

 of the number of epitheUal gland individuals present, as indicated by a 

 plurality of ducts. In consequence of a Uke mode of thinking, the
