sented, in different parts, hepatization and vomicae (one of the 
abscesses would have held eight or ten ounces) ; and in other 
parts there was as decided congestion as accompanies the most 
acute disease. The tubercles were few, and of small size. The 
process of hepatization, and softening, and abscess hud gone on 
until there was comparatively only a small part of the lungs left for 
the purpose of respiration. The natural consequence of the over- 
working of the remaining part was congestion and rupture of the 
capillary vessels. Was the disease originally hepatitis? I am 
much inclined to believe so. I pretend not to understand the 
relation between them. The various symptoms and lesions that 
have been presented in different cases make me doubtful as to the 
order of precedence. Are they not, in fact, contemporary — the 
effects of one common cause — the indications of the same fatal 
diathesis, and the symptoms and the lesions of the one or the 
other prevailing in proportion as the digestive or the pulmonary 
systems were naturally weak, or had been abused ? There is 
much room for useful reflection here; but, at present, I am a 
mere recorder of facts.

Most of the small islands or keys, as they are called, com- 
posing the extensive group of the Grenadines, are formed, for 
the most part, of tuf or decayed lava, and ferruginated volcanic 
ashes. The cultivation of the more practicable spots of these 
islands yields a valuable produce in cotton and Indian corn ; but 
they are all destitute of water, and the inhabitants depend on 
rain-water, or water wells, dug, as those of Point Saline, in tuf, 
and are subject to the action of the tides. In those instances 
in which the planters have attentively observed the causes of the 
few diseases these islands are subject to, the same phenomena 
of the origin, progress, and annual recurrence of the Guinea- 
worm have been remarked. A very ingenious and acute ob- 
server, Mr. John Campbell, proprietor of one of the largest of 
them, called Mystique, and of a gang of about five hundred 
negroes, favoured me with the following interesting information, 
in the year 1796, at St. Vincent : — He told me that about the 
year 1793 he first perceived among the negroes this disease ; 
that never till then had any symptoms of it appeared, to his 
knowledge ; that ever since November of that year it makes its 
appearance about the beginning of the winter months, and con-
