and discharge it in the face of the attendant — he would spit and 
throw his saliva on every one around him, and once he suddenly 
sprang out of bed, seized the large syringe, which was filled with 
an injection of turpentine, and advanced against those that were 
present, spitting, and discharging its contents at them. They 
escaped, by the door, and he, rushing after them, closed and 
locked it. Before they could break it open, which they instantly 
attempted, he had tried the window, which was secure, and 
had climbed upon the drawers. He then returned to open the 
door; but before he could accomplish it, he fell insensible. 
Once he threatened the doctor dreadfully — attempted to get out 
of bed for the purpose of attacking him — tossed himself about 
and gnashed his teeth, his countenance bearing such an impres- 
sion of rage and despair, as to remind his attendants of the 
pictures of persons tormented in the infernal regions. Contrast 
this horrible scene with the following ones. See the Duke of 
Richmond sitting calmly down to arrange some private affairs, 
and writing the most affectionate letters to those whom he loved. 
See Miss M‘Clive calling around her the different members of 
her family, — addressing to some a word or two of admonition 
that would, under such circumstances, have their due effect ; and 
many a word of kindness to all that would never be forgotten, 
and actually spending her last breath in imploring a blessing on 
them. 
But I have done ; I pretend not to explain all the wanderings 
and delusions of a delirious mind ; but I have endeavoured, in 
the last few observations, to trace a connexion — a stronger one 
than most imagine — between these delusions and the previous 
habits of the sufferer. My object in this will be hereafter 
apparent. 
ON HOCK LAMENESS, IN REPLY TO PROFESSOR 
DICK. 
By Mr. W. C. Spooner, Southampton. 
[The accompanying engraving will convey some idea of the ap- 
pearance of the pulley-form portion of the astragalus in the horse 
whose case was related by Mr. W. C. Spooner in The Vete- 
rinarian for July, and animadverted on by Professor Dick, 
in the August number of that Journal. Deep in the groove 
of the pulley is evident discolouration and depression — there 
is loss of substance — there is apparent ulceration of the carti- 
lage. On the corresponding central projection of the articular 
surface of the head of the tibia there was a deeper stain, and 
a considerably deeper depression. The surface was rough, and
