Answer, dated 15th Oct. 1867.

Being rather long, and alluding to other matters, I give only the substance of it :—1. The Cough.—Not materially improved, but the parents think 'rather better.' 2. The Expectoration.—In quantity much the same, but in quality much better. 'It is less purulent, and floats in water better than formerly.' 3. The blood in expectoration.—Still some blood now and then. Some days not quite so much. 4. The appearance of Pharynx.—Greatly better, 'in fact it is now pretty well.' It was improving by the caustic, but 'the sulphurous acid has done it still more good.' 5. The General Health.—Never was very bad. 'He feels quite well except the cough.'

It strikes me that this answer is on the whole extremely encouraging. Almost every symptom slightly improved, others decidedly so, whereas formerly he was always getting rather worse.

Oct. 21. Having heard by an oral message on 19th that———was still keeping rather forward, I visited Peebles to-day, and in consultation with Dr. C. we agreed as follows :—'Decidedly better in every respect. We think the sulphur fumes have served him much. Should the improvement continue, we consider it not a case of cured phthisis, but of threatened phthisis arrested in the meantime.

Note.—From the result of this case, Dr. C. has been using the fumes, and sulphurous acid internally, in a bad type of scarlet fever prevailing in Peebles at present, and authorizes me to state that he is quite satisfied of their good effects.

Note for Third Edition.—Like Dr. C. I have since tried the same plan in scarlet fever, and found it to answer well,—viz., occasional fumes, spray or sulphurous acid gargle, and acid internally every hour.

Note for Seventh Edition.—Dec. 4.—Dr. Crawford reports 'Patient improving, and gaining weight.'

Note for Thirteenth Edition.—Feb. 27, 1868.—Since last report he has passed through a severe attack of influenza, accompanied with congestion of part of left lung, and expectoration of bloody phlegm. This attack exhausted his strength greatly, but now (as Dr. C. writes) 'he is in a more favourable state than he has been for four months.'
