tail as violently curved upwards; there was hoarse rattling in 
his throat, his eyes were bloodshot, and his tongue protruded. 
He died in ten minutes. 
Post-mortem , at 5 p.m.—The skull and spinal canal alone 
were opened. Over the whole surface of the brain serous 
effusion existed, as also into the ventricles of the brain. 
The brain substance also exhibited numerous vascular points. 
The membranes of the cord were also very vascular, and the 
spinal vessels gorged with blood; but no change was noticed 
in the nervous substance itself. 
3rd March.—Dog, No. 9, a puppy. 5 SS of acid w r as given ; 
he at once fell down convulsed, and died within ten 
minutes. A post-mortem was made one hour afterwards. The 
heart was full of dark fluid blood. The lungs also, together 
with the liver, were gorged with fluid blood. The kidneys 
w r ere deeply congested, and the bladder full of dark urine, 
which smelt strongly of the acid. The vessels of the brain 
w r ere also gorged, and there w r as a thick layer of albuminous 
effusion over the surface of the brain. 
3th March.—Dog, No 10 , as large as a pointer. At 7.6 
a.m. forty drops of acid in half an ounce of w^ater were given. 
He at once began to paw his mouth and in two minutes 
jumped up, broke his string, and ran, staggering, for about 
twenty yards, when he fell over, but w 7 as able to get up, and 
kept jumping in a gyrating manner for some time, with his 
hind legs well under him. The breathing was accompanied 
by a rattling noise in the throat. At 7.15 his bow r els were 
moved ; motion had scybalae. He gradually recovered after 
this, and w r as all right in half an hour. On the 7 th and 14th 
March respectively, 5 j of the acid in 5 SS of water was given, 
with merely a repetition of the symptoms before described; 
there was no increase, and he recovered fully in half an hour 
each time. 
3rd April, 6.15 a.m., 3 iss of acid in tepid w r ater was given. 
In thirty seconds the dog staggered and fell, but was able to 
rise. His breathing became heavy, and in another thirty 
seconds he again fell over and was then unable to rise. His 
pupils were now found widely dilated, but eyes not particu¬ 
larly red. The spasmodic action of the limbs was continuous 
and strong, and body curved into a ball-like form. At 6.40 
he began to revive, and in another hour's time appeared 
quite recovered. 
4th April, 6.22 a.m., 3 'ij of acid were given in tepid water, 
w T hen he fell down at once ; the breathing became stertorous, 
eyes bloodshot and pupils widely dilated, w 7 ith the tongue 
somewhat protruding; spasms of limbs strong, and body
