mination, this appendix was observed to be a diverticulum from the ileum. At the place of its union with the ileum it was enlarged and inflamed, in common with the upper portion of the small intestines; the remaining part was of a natural colour, and so intimately connected by its blind extremity at the umbilicus, as to leave little doubt of its being an original mal-formation. The ileum, above this appendix, was very much inflated, extremely vascular, and in size, equal to the transverse colon; while the lower portion was greatly contracted, and twisted round the diverticulum; and in this manner had been the means at least of aggravating, if not of inducing the inflammation and its consequences in this particular part of the intestinal canal. This portion of the ileum was of a dark, livid appearance, and had lost its natural tenacity. The great intestines were found completely emptied of their contents, and preter-naturally contracted in their diameters throughout their course.

The omentum, transverse colon, and stomach, were, at first, altogether concealed by the distended state of the small intestines; and found in close contact with the diaphragm. The omentum was irregularly drawn together. No unnatural appearance of the transverse colon was remarked. The stomach lay in a circumscribed situation, was not more than two inches in width, and contracted in the same proportion throughout its whole extent. It was entirely empty; upon a minute inspection, no discolouration or affection of its coats was seen.

From the annexed draught, by the ingenious Mr. Inderwick, a student of medicine of this city, the peculiar structure of the parts affected will be more accurately understood.

A. The manner in which the diverticulum was connected

to the umbilicus.

B. The diverticulum.

C. The manner of its union with the ileum.

D. The upper portion of the ileum, enlarged and extremely vascular.

E. The lower portion, contracted and in a state of approaching sphacelus.

Analysis of BALLSTON WATER. Communicated in a Letter to Dr. DAVID HOSACK, from ROBERT L. LiVINGSTON, Esquire, during his late residence in France.

TOURS, September 10, 1807.

DEAR SIR,

HAVING received some benefit from the mineral waters of Ballston, of late years frequented by invalids from every part of the continent, I determined to have them analysed, and accordingly had two dozen bottles hermetically sealed, which arrived here in a perfect state of preservation. Presuming that a knowledge of the component parts of those waters may be of public benefit, I have the honour to transmit herewith the analysis of them, by one of the most celebrated chemists; and to request that you will have the goodness to make it public.

On my arrival at Paris, I drank two bottles of the water, and found no difference in the taste or effect, than that experienced last year at Ballston, from which I conclude that the component parts suffer little or no alteration from transportation.

Having this moment heard of a safe opportunity to New-York, I have only time to assure you of my esteem and respect.

Your most obedient servant,

ROBERT L. LIVINGSTON.
