I have mentioned the scorbutic habit as distinguished from the scurvy, but there seems to be no difference except in degree; for a person may be laid to labour under the disease before it betrays itself by any obvious symptom, and it must have gathered a certain degree of force before visible symptoms are produced. The chief mark of this latent and incipient stage of the disease is that incurable state of ulcers that has been mentioned, whether they appear spontaneously or in consequence of slight accidents. There is another mark of this scorbutic habit which is not mentioned in any description of the disease I have ever seen. It is a soft, indolent tumour which arises under the skin on a part which has received a small blow, or contusion, so slight as not to break the skin. It most commonly appears about the elbow or fore-arm, and generally disappears without any inconvenience, what it contains being absorbed. A surgeon, who opened one of them, (a practice, however, not to be approved of) informed me that it consisted of fluid blood. We may also reckon a languor, or sense of weight, as one of those marks of scurvy which occur before the more obvious symptoms appear. In this state of the disease, the articles of lesser powers, such as malt and melasses, may be of service by preventing its farther progress, or the appearance of actual symptoms, and by restoring the constitution. In some of the early stages of this disease the effervescing mixture of acids with fixed alkali may probably also be of use. I never could perceive any sensible benefit in those cases in which I tried it, though some of the gentlemen of the fleet reported to me that they thought it of service.
