of the whole cesophagus were made according to the method outlined 
in the introduction in order to determine positively the distribution 
of glands in them. In the case of the cat three such preparations 
were made, all of which demonstrated the complete absence of 
glands below the level of the cricoid cartilage. 
The cesophageal glands of the dog, like those of the opossum, are 
composed of two kinds of cells, mucous cells and serous demilunes. 
In this respect my observations confirm the statements of Klein (79), 
Renaut (97) and Helm (07) and are opposed to those of Rubeli (90)

and Haane (05). ‘The latter observer, it is true, does not specifi- 
cally state that demilunes are absent, but implies it in the statement 
that he was unable to find intercellular secretion-capillaries. The 
demonstration of the demilunes in the cesophageal glands of the dog 
is no difficult matter if thin sections of well-fixed tissue are examined, 
and if an efficient differential staining method is employed, for 
they occur in relatively large numbers in all the esophageal glands, 
although less numerous than in the glands of the opossum and rac- 
coon (Procyon). For staining neutral satireviolet-safranin is par-
