en recently found and exhibited to the Paris
Academy of Medicine. He is a Roumanian Jew of thirty who began to
ossify twelve years ago, first up the right side of his back, then down
the left side. He has hardened now to the nape of the neck, his head is
turned to the left, and the jaws are ankylosed. He can still move his
arms and legs a little with great difficulty.

Akin to the foregoing condition is what is known as petrifaction or
ossification of portions of the living human body other than the
articulations. Of the older writers Hellwigius, Horstius, and Schurig
speak of petrifaction of the arm. In the Philosophical Transactions
there was a case recorded in which the muscles and ligaments were so
extensively converted into bone that all the joints were fixed, even
including the vertebrae, head, and lower jaw. In a short time this man
was, as it were, one single bone from his head to his knees, the only
joints movable being the right wrist and knee. For over a century there
has been in the Trinity College at Dublin the skeleton of a man who
died about 20 miles from the city of Cork. The muscles about the
scapula, and the dorsum of the ilium (the glutei) were converted into
great masses of bone, equal to the original muscles in thickness and
bulk. Half of the muscles of the hips and thighs were converted into
bone, and for a long time this specimen was the leading curiosity of
the Dublin Museum. In the Isle of Man, some years ago, there was a case
of ossification which continued progressively for many years. Before
death this man was reduced to almost a solid mass of bony substance.
With the exception of one or two toes his entire frame was solidified.
He was buried in Kirk Andreas Churchyard, and his grave was strictly
guarded against medical men by his friends, but the body was finally
secured and taken to Dublin by Dr. McCartney.

Calculi.--In reviewing the statistics of vesical calculi, the strangest
anomalies in their size and weight have been noticed. Among the older
writers the largest weights have been found. Le Cat speaks of a
calculus weighing over three pounds, and Morand is accredited with
having seen a calculus which weighed six pounds. In his statistics in
1883 Cross collected reports on 704 stones, and remarked that only nine
of these weighed above four ounces, and only two above six, and that
with the last two the patient succumbed. Of those removed successfully
Harmer of Norwich reports one of 15
