his sensations. He apprehended some, however, to which he could 
not give utterance. He had little use of language, and articulated 
indistinctly. He was reported to have imperfect vision in the left 
eye, and to have been lame from his birth ; but he walked much, 
inclining forwards and to the left side, and touching the ground 
with the toes only of the left foot: he used no support. His left 
arm was nearly useless. 
The apparent relation between the several portions of the brain 
in their development; the normal state of the optic nerves in con¬ 
nexion with the defective condition of the right pair of the tuber- 
cula quadrigemina; the similarity in the state of the arteries sup¬ 
plying either hemisphere of the brain; the imperfect and perverted 
development of the left extremities in connexion with the deficiency 
in the right hemisphere of the brain; and the anatomical condition 
of the left hip-joint, seem to the author to be the principal points of 
interest in the case which he detailed.

Propositions concerning Typhus Fever, deduced,from numerous Obser¬ 
vations. By Dr. Perry. 
1st. That typhus fever is an idiopathic disease, solely produced 
by contagion, that is, by the introduction into the system of a spe¬ 
cific animal poison. 
2nd. That this specific poison is (as far as yet known) only gene¬ 
rated in the human body during the course of this idiopathic fever. 
3rd. That no other fever, arising either from general causes, as 
cold, fatigue, improper ingesta, local lesions, or marsh miasmata, is 
capable of generating this specific poison, or, in other words, pro¬ 
ducing contagious typhus. 
4th. That this contagious idiopathic typhus runs a certain course, 
which may be modified, but cannot be checked, and is distinguish¬ 
able from all other fevers by certain symptoms, which, in a greater 
or less degree, are uniformly present during its course. 
5th. That the following Is the usual course of the symptoms by 
which contagious typhus may be distinguished, viz. languor, nau¬ 
sea, frontal headach, rigors, loss of strength and appetite, followed 
by increase of thirst, quickened pulse, heat and dryness of skin, pain 
of back, or general soreness over body. The tongue becomes white at 
the base and centre, florid at the tip and edges, and on the fifth day 
from the first attack of headach, rigors, or nausea, a reddish slightly 
elevated, but irregular papular or measly eruption comes out, some¬ 
times sparingly, at other times thickly scattered over the trunk and 
limbs, but rarely appearing on the face. As the fever advances in 
severity, the frontal headach abates, the tongue becomes dry and brown
