SOLITARY GLANDS OF THE LARGE INTESTINE. 
The solitary gland of the large intestine, seen by the naked 
eye, has the appearance of a small circular opening in the 
mucous membrane, bordered by an elevated rim. With the 
microscope, the elevated rim and sloping sides of the opening 
are seen to be composed of a reticular framework and alveoli

A solitary gland of the large intestine, magnified nineteen times. The 
alveoli of this portion of the membrane are deep and large, measuring 7 ^ 3 of

smaller and the septa thicker. In the floor there is a vascular network,

similar to the rest of the mucous membrane, excepting that 
the alveoli are more angular and deeper, and the septa thinner. 
The alveoli are so deep that their floor is not perceptible ; 
they are larger than those of the rest of the membrane, mea- 
suring j-±j by 2^0 of an inch ; and the septa, measuring 
of an inch in breadth, contains only a single capillary. The 
alveolar structure is continued to the bottom of the crater of 
the gland, where I thought I could perceive the apertures of 
several follicles. 
ON THE DIGESTION OF AMYLACEOUS SUBSTANCES. 
By M. Blondlot. 
In a lengthened memoir under this title, divided into three 
parts, and published in the Annales cle Chtmie et de Physique , 
for Feb. 1855, the author advances some novel views. 
In the first part, he considers the constitution of fecula —
