t when due to
new bone round the edge of the acetabulum may be greatly relieved by
removal of the bone--a procedure known as _cheilotomy_. Loose bodies and
hypertrophied fringes if causing symptoms may also be removed by
operation.

When stiffness and grating on movement are prominent features we have
found the injection of from half to one ounce of sterilised white
vaseline afford decided relief.

The patient should be nourished well, and there need be no restriction
in the diet such as is required in gouty patients, so long as the
digestion is not impaired. Benefit is also derived from the
administration of cod-liver oil, and of tonics, such as strychnin,
arsenic, and iron, and in some cases of iodide of potassium. Luff
recommends the administration over long periods of guaiacol carbonate,
in cachets beginning with doses of 5-10 grs. and increased to 15-20 grs.
thrice daily. A course of treatment at one of the reputed spas--Aix,
Bath, Buxton, Gastein, Harrogate, Strathpeffer, Wiesbaden, Wildbad--is
often beneficial.

In some cases benefit has followed the prolonged internal administration
of liquid paraffin.

On the assumption that the condition is the result of an
auto-intoxication from the intestinal tract, saline purges and
irrigation of the colon are indicated, and Arbuthnot Lane claims to have
brought about improvement by short-circuiting or by resecting the colon.

Residence in a warm and dry climate, with an open-air life, has been
known to arrest the disease when other measures have failed to give
relief.

The application of radium and the ingestion of radio-active waters have
also been recommended.

#Haemophilic# or #Bleeder's Joint#.--This is a rare but characteristic
affection met with chiefly in the knee-joint of boys who are the
subjects of haemophilia. After some trivial injury, or even without
apparent cause, a haemorrhage takes place into the joint. The joint is
tensely swollen, cannot be completely extended, and is so painful that
the patient is obliged to lie up. The temperature is often raised (101
to 102 F.), especially if there are also haemorrhages elsewhere. The
blood in the joint is slowly re-absorbed, and by the end of a fortnight
or so, the symptoms completely disappear. As a rule these attacks are
repeated; the pain attending them diminishes, but the joint becomes the
seat of permanent changes: the synovial membrane is thickened,
abnormally vascular, and coloured brown from the dep
