of fine division for being digested. But the action of Cocoa on 
the nervous system is much less pronounced than that of tea, 
or coffee, owing to the comparatively small amount of thein; 
or cafiein, which it contains. In St. James’s Street, London, 
when Queen Anne reigned, there was a famous Chocolate house 
known as the “ Cocoa Tree.” Its frequenters were Tories of the 
strictest school. In the course of time it developed into a more 
general club. Dr. Garth whilst sitting there had his snuff-box, 
which was highly ornamented with diamonds, so repeatedly 
borrowed by the poet Rowe in order to gain notice, that at last 
he took out his pencil and wrote on the lid the Greek characters 
 (phi.): P (rho.)=‘‘ Fie, Rowe!” 
COD. (See FisH and Om.) 
THE Cod is found by those who have made competent research 
to be one of the least digestible fish, though containing but little 
fat. Its fibre is coarse, and woolly, but Cods’ heads baked in 
the oven are excellent. The ancient Greeks held the Ccdfish 
(Morrhua) in high estimation, preparing it with grated cheese, 
vinegar, salt, and oil. Its stomach (which it is said to have the 
faculty of turning inside out) is mostly found quite empty, and 
clean, as the result of its enormous digestive power, which habit 
has, without doubt, a great influence on the flesh, helping to keep 
it healthy, and well scoured. Cods’ sounds, or the swimming 
bladder, do not dissolve as gelatine on boiling; they are but 
sparingly nutritious, and more an object of fancy than useful 
as food. From the fresh livers of Codfish (subjected to a steam 
bath) is procured the highly curative Cod-liver oil, considered 
elsewhere in these pages (see “ Oris”). Par excellence it is ot 
the most essential service as a food, and as a medicine, in 
pulmonary consumption. 
Underlying this scourge, which has hitherto proved so 
widespread, and fatal, there are now found to be special 
micro-organisms which die out under the modern open-air 
treatment, together with an abundance of generous food even 
to excess. Similarly an intensity of light will completely destroy 
the micro-organisms of erosive skin disease external to the body ; 
but the light for safe concentration upon such diseased surfaces 
has to be deprived of those rays which burn (red, green, and 
yellow), whilst it exercises its beneficent action solely by the
