ON THE ORGAN OF MARRIAGE. 
which I have collected amongst animals, have enabled me to fix the situation of 
the organ in man and animals. Before pointing out upon the brain and skull the 
place where it is to be found, I must enter into some anatomical details. 
The region of Philoprogenitiveness, as laid down in the works or on the bust 
which phrenologists have in their hands, occupies too extended a space, and com¬ 
prehends two distinct portions of the brain, the one placed at the middle part 
(No. 11), the other (No. 8) more laterally 
and outwards. The first appears to me to 
be the seat of the organ of Philoprogenitive¬ 
ness, the other that of attachment for life, or 
marriage. I have already found this latter 
region well developed in two persons who 
had very early manifested the desire of be¬ 
ing united to each other, and without being 
induced to do so by other motives than such 
as leads to four-fifths of marriages. I have 
found, on the other hand, the same region little developed in persons who had 
naturally a repugnance for marriage. As a few observations will not suffice to 
establish a certainty, I would entreat phrenologists who have opportunities of 
making numerous observations to ascertain if new and carefully noted facts might 
be found to confirm my remarks. 
Except in quadrumanous animals, it is not in the region of the occipital bone 
that we ought to look for the seat of the organ which leads animals to become 
united for life. It must be recollected that I maintained this point in Anatomy 
while describing the occipital region of quadrupeds and birds ; in the former it is 
entirely filled by the cerebellum; in the latter it contains the cerebellum, and a 
great part of the acoustic apparatus. 
It is then in the posterior parietal region that we should look in these two > 
classes for the seat of the organ in question. I have compared with care the 
skull and brain of a species of bird well known to live in a state of union, as well 
as those of species which live separate from their female after impregnation. 
There is a remarkable difference which I have observed between them. The' 
portion of the skull corresponding to the middle part of the posterior border of the 
cerebral hemisphere (No. 8), is veryjprominent in all birds which live in a state of 
union. Such are the following skulls and brains which have presented to me this, 
form of organization very apparent. The Buzzard, the Raven, the great Screech 
Owl, the Hooded Crow, the Magpie, the Jackdaw. The brain of the Hooded 
Crow, of the great Screech Owl, and of the Buzzard, will be found represented in 
my work. We should remark, that in these three species, which live in a state of
