492 THE TREATMENT OF DISEASES. 



by the late Dr. Parkes, and they are so essentially practical in their nature 

 that they cannot fail to be of service. We reproduce them in a slightly 

 condensed form : 



1. The supply of fresh vegetables and fruits by all means in our power. Even 

 unripe fruits are better than none, and we must risk a little diarrhoea for 

 the sake of their anti-scorbutic properties. In time of war every vegetable 

 should be used which it is safe to use, and when made into soups almost all 

 are tolerably pleasant to eat. 



2. The supply of dried vegetables, especially potato, cabbage, and cauliflowers ; 

 turnips, parsnips, &c., are less useful ; dried peas and beans are useless. As a 

 matter of precaution these dried vegetables should be issued early in a campaign, but 

 should never supersede fresh vegetables. 



3. Good lemon-juice should be issued daily (one ounce), and it should be seen 

 that the men take it. 



4. Vinegar (half ounce to one ounce daily) should be issued in the rations and 

 used in cooking. 



5. Citrate of potash or tartrate of potash should be issued in bulk and used in 

 water as a drink or added to the food. The easiest mode of issuing these salts 

 would be to have packets containing enough for one mess of twelve men, and to 

 instruct them how important it is to place them in the soups or stews. Possibly 

 they might be mixed with salt and issued merely as salt. 



The following directions for the preservation and use of lemon-juice were 

 issued by the Board of Trade. They are intended chiefly for the information of 

 shipowners and shipmasters, but are likely to prove of service under other 

 circumstances. 



Every ship on a long voyage should be supplied with a proper quantity of lime 

 or lemon juice. 



The juice, having been received in bulk from the vendors, should be examined 

 and analysed by a competent medical officer. All measures adopted for its preserva- 

 tion are worthless, unless it can be clearly ascertained that a pure article has been 

 supplied. 



Ten per cent, of brandy (sp. gr. 930) or of rum (sp. gr. 890) should afterwards 

 be added to it. 



It should be packed in jars or bottles each containing one gallon or less, covered 

 with a layer of oil, and closely packed and sealed. 



Each man should have at least two ounces (four table-spoonfuls) twice a week, 

 to be increased to an ounce daily if any symptoms of scurvy manifest themselves. 

 The giving out of lime or lemon juice should not be delayed longer than a fortnight 

 after the vessel has put to sea. 



SEA-SICKNESS. 



"We have no intention of entering into a scientific discussion as to the causes 

 of sea-sickness ; those of our readers who are not suffering from mal de mer would 

 probably be but little interested in it, whilst those who are paying involuntary 

 tribute to old Neptune are certainly not in a fit condition to appreciate it. There is
