continued every night whilst necessary. A dry flannel should 
be substituted around the part by day. 
Salt is not present in the body, or in plants, unless conjoined 
with phosphates. The Cerebos Salt now deservedly in vogue 
with grocers contains a small definite proportion of the mixed 
phosphates as found in wheaten bran; it is a remarkably fine 
and white Salt, whilst it does not cake on a damp, or foggy day. 
During the course of an attack of lung inflammation (pneumonia) 
it is a strange fact that the urine (which then becomes scanty, 
and high-coloured) ceases to contain chlorides, such as are 
commonly present in healthy urine. At the same time these 
chlorides are found to be retained in the matters excreted trom 
the lungs. Whilst this derangement persists, table Salt (chloride 
of sodium) should be withheld from the food, whether liquid 
or solid, and fresh lemon-juice should be added to the weak 
broths, or other simple drinks. When the expectoration becomes 
free, during convalescence, the chlorides are again discoverable 
in the urine. For serving to cure a catarrhal cold in its con- 
tinuous stages, common Salt, when triturated, has a remarkable 
efficacy. Though probably taken liberally at the same time 
as a condiment with food, it does not have in such form any 
similar results as when dried, and patiently rubbed up with dry 
powdered sugar of milk for half an hour together (one part of 
the Salt to nine parts of the milk sugar). The mixed powder 
should be then kept in a well-corked, wide-mouthed | bottle ; 
half a teaspoonful to be given on the tongue three times in the 
day. A dynamic virtue is thus acquired by the Salt resembling 
that contributed to crude quicksilver (comparatively inert as 
a medicine) when pounded up with conserve of roses into what 
is known as “ blue pill,” a potential drug even by giving only a 
few grains thereof. Provings of table Salt taken in excess by 
healthy persons have produced all the symptoms of chronic 
catarrh. 
SANDWICH. 
SueTonius, who lived in the times of the Cwsars, tells of the 
Sandwich as known among the Romans under the name “ Offula ;’ 
though our English term is given aiter John Montagu, fourth 
Earl of Sandwich (1780), who used to have slices of bread with 
ham between them brought to him at the gaming-table, so that
