OBSERVATIONS ON SOME DISEASES OF THE HEART. 437 
of marble. At the superior part of the heart these spots pene- 
trated about half way through its tissue, while towards the infe- 
rior part it could be traced through every portion of the sub- 
stance. They were less profound and extended, and of a less 
deep colour, in the right ventricle. The membrane which covered 
the heart on that side was about three lines in thickness, and 
infiltrated with a brown fluid ; but all traces of this were com- 
pletely lost in the left ventricle, which was altogether transformed 
into a lardaceous tissue. The auricles had acquired an unna- 
tural size by the infiltration of their tissue.” 
Case II. May 20th, 1830. — A mare, three years old, pre- 
sented the following symptoms : — a general tremulous motion — 
quick and laborious respiration — small, hard, and accelerated 
pulse — cutaneous perspiration abundant and general — and a stag- 
gering walk. 
M. Delalande had recourse to friction long continued, after 
which the horse was warmly clothed. Two setons were inserted 
in the chest. 
2\st. — The unfavourable symptoms have all disappeared. The 
setons have discharged profusely. Feed moderately, and occa- 
sionally give gruel. 
30th. — She returned to her work. 
Sep. 15th . — A return of the unfavourable symptoms, but under 
a milder form. Application of the same means, and with the 
same results. 
Towards the end of November the proprietor removed her alto- 
gether from work, and sent her to grass, in order to get her into 
condition for the fair of Careme a Caen ; and she would have 
been sold had it not been for a kick in the hock. Being again 
taken to work, she did well until the 31st of March in’the following 
year, and then her illness returned with more than usual severity, 
and, after three days, notwithstanding all our care, she died. 
On opening her, a considerable quantity of red serous fluid was 
found in the pericardium, and this was the only lesion that could 
be detected. The heart was unaffected, but the pericardium 
appeared to be somewhat thinned by the pressure of the fluid 
which it contained. She was in good condition, and her muscu- 
lar power was undiminished. 
Case III. 20th. Sep. 1840. — Intestinal colic appeared to 
attack a colt six months old, presenting the following symptoms : 
the breathing quick — the pulse small, wiry, and accelerated — 
the mucous membrane red — and a tremulous motion of the pec- 
toral and scapular muscles. 
Two pounds of blood were withdrawn — emollient injections 
administered. The symptoms diminished. A second bleeding
