of the Materia Medica; the same structure in 
glaucous plants which covers them with a resi- 
nous secretion: a similar structure in the leaves 
of the myrica cerifera, or wax bearing myrtle, by 
which they are covered with a green ceratious 
deposition ; but above all, the stucture of the necta- 
ries of all plants, particularly in the strobiles of 
common hops, which throw out at the base of 
the squame, a secreted narcotic bitter resin, called 
by Dr. A, W. Ives lupulin ; and the nectaries of the 
melianthus major, which contain, asa fluid is 
Contained in a cup, half a dram or more of honey— 
are a few instances of thousands which might be | 
adduced, to shew that the glandular structure not 
only exists in vegetables, but thatit is, by its ex- 
cretory ducts and other circumstances, a structure 
anatomically similar to animal glands. The 
verisimilitude is palpable. Indeed, it is not only 
upon the irrelevancy and insufficiency of this sup- 
posed analogy of simple structure im the uterus 
and in vegetables which secrete acids, mucilages, 
gums, resis oils, &c. that I believe too much 
of a glandular office is assigned to the uterus, in 
the production of the catamenia. There is really 
no sufficient foundation in the anatomy of the part, 
for ascribing so much of its function, to the elimina- 
tion of a species of blood, different it is true in 
Many essential points, from common blood, but 
nevertheless sufficiently resembling it, to have 
eluded the observation of many men of distinguish- 
ed acumen and knowledge. The truth seems to 
me to lié midway between these two extremes, 
where indeed that penetrating physiologist, Mr. 
Hunter, saw it. And the kind of change effected 
by the agency of the uterus in common blood 
determined to it in a super-abundant quantity, and 
in periodical regularity, by some inscrutable neces-
