Southward from the Capitol Square is the spacious and comfortable Executive Mansion, with an extensive lawn, on Eagle Street. On the same street, to the northeast of the Square, is the City Hall, a fine Gothic building with an elaborate bell tower. Also on Eagle Street is the Albany Medical College, having one of the finest Medical Museums in the country. Among its curios is the embalmed body of Calvin Edson, the "walking skeleton." This curious man came to Albany in 1830, being then forty-two years old and five feet two inches high, yet weighing only sixty pounds. He exhibited himself, and appeared in a play as _Jeremiah Thin_. He had a good appetite, but the more he ate the thinner he grew, until in 1833, the food ceasing to nourish him, he literally starved to death amid plenty, and when the end came, weighed but forty-five pounds. His widow sold his body to the college, and he now stands in a glass case, preserved with the skin on, labelled "No. 1," and excepting discoloration is said to appear not very different from when living. On the northern side of the Square is the Albany Academy, one of the chief city schools, where Professor Joseph Henry was for several years an instructor, and noted as the place where he first demonstrated the theory of the magnetic telegraph by ringing a bell by an electric spark transmitted through a mile of wire strung around the room. The Dudley Astronomical Observatory is a small but imposing building upon an eminence overlooking the Hudson, having a munificent endowment begun by Mrs. Blandina Dudley in memory of her husband, a wealthy Albany merchant. A charming spot is Washington Park, westward from the Capitol, an enclosure of eighty-one acres, surrounded by ornamental villas, with magnificent views and most tastefully arranged. Part of this Park is land given the city by King James II. INTERESTING BUILDINGS.
