was going on very well, and had drunk the gruel. 1 then order¬ 
ed him a little warm bran mash, which he also ate. 
8 A.M. —I saw him, and found that his pulse was slower, but 
his breathing quicker than natural, and his throat sore at the 
top. 
9 A.M. —I ordered him to be taken very slowly home, and to 
have gruel two or three times on the road. After he got home, 
he was placed under the care of a veterinary surgeon (Mr. 
Matthews). His throat was sore for awhile, but in a week after¬ 
wards all was right again. 
Some few years ago a whole hen’s egg was given to a very 
valuable hack mare, near here. It stuck in the oesophagus. A 
farrier was sent for out of this town, who introduced a hand-whip, 
or something else, to dislodge it; but ruptured the oesophagus, 
and the mare died in consequence. I have seen many horses 
choked with one thing or other, but never had occasion to use 
the probang before. 
COW,S POISONED BY WHITE LEAD. 
By Mr. M. Pottie, YokeVj near Glasgoiv. 
During the last two or three years, I have met with four in¬ 
stances of the poisonous effects of white lead in milch-cows, and 
I have heard of several others. 
The Symptoms are always the same; and the patient dies 
some time between the second and eighth day after she is observed 
to be ill. At first the cow is dull, heedless, unwilling to move ; 
the eye is fixed, dead-like, void of expression; the bowels are 
obstinately constipated ; the skin is cold, and the coat staring; 
when the pulse is altered, it is a little slower than in health. 
There is no hunger and no thirst. Drenches are given with diffi¬ 
culty, for the patient is unwilling to swallow. Subsequently the 
cow becomes delirious. She seems to be quite unconscious. 
At liberty in a loose house, she walks round and round, steadily 
and composedly, till she happens to come in contact with the 
wall. Then she stands, places her forehead deliberately against 
the wall; pushes, at first feebly, afterwards with all her strength. 
The resistance seems to excite her. She never removes her head ; 
but, as her passion rises, she throws her whole strength into the 
effort; she bellows hideously, fights with her fore feet, and 
screams, as if choking with rage. With the tail erect, the tongue 
hanging out, the mouth full of foam, and the whole frame qui- 
vciing with intense excitement, she persists in her struggles, as if
