But let it not be alleged, on the most dubious scientific grounds, that such a measure has a eugenic justification. It is very difficult to find satisfactory evidence as to the harmful effects of a moderate mixture of races as nearly allied as the ’Jewish, the Nordic, the Alpine, and the Medi- terranean. Evidence has in fact been adduced that a moderate intermixture produces racially beneficial results. By most observers in this country it is believed that Germany has benefited rather than suffered culturally through the admixture of Jews in her population. In the interests of elementary justice it is to be sincerely hoped that in Germany sexual sterilisation will not be applied in a spirit of racial animosity; but if it is so utilised, may the motive not be misconstrued as either eugenic or economic in the senses advocated in the German draft Bill. At present a departmental committee is in this country giving detailed consideration to the problem of sterilisation. It is as yet impossible to foretell what attitude it will adopt in its final report. Should the committee pronounce a cautiously favourable verdict that voluntary sterilisation has a limited application to carefully selected persons within certain general groups, it is to be hoped that public opinion will not run away with the idea that the adoption of such a policy will be the logical prelude to its misuse as an instrument of tyranny by racial or social majorities. No biological innovation of social signifi- ance is free from possibilities of abuse ; and all such innovations are likely to find different legal expres- sions in different countries. If the principle of sterilisation is, with appropiate safeguards, adopted in this country, it can be taken as certain that it will be applied in a way that expresses the social consciousness which prevails in England rather than that which is now sweeping through Germany.

JEJUNOSTOMY To the Editor of THE LANCET SIR,-Please allow me a brief reply to your anno- tator (p. 1190). It still seems to me a pity that this easy operation is " so seldom performed," and I venture to suggest to younger colleagues that they should try it. My results have been so good that I am glad to learn that Lameris came to the same conclusions. To the question, "Will a duodenal tube do all that jejunostomy can accomplish I " I should reply, "Certainly not!" Compare the calibre of a duodenal tube with the 14-16 F. catheter used in jejunostomy as regards the amount of nourish- ment which can be given. Food introduced into the duodenum is apt to regurgitate into the stomach and promotes the flow of gastric juice which physi- cians want to avoid. A jejunal tube is discreetly hidden by the clothing and does not prevent work. But the crucial question for any one of us, if we had an ulcer would be, " What is the relative mortality of jejunostomy and partial gastrectomy ? " My answer would be (cf. Mayo), " Any surgeon-even an expert’—who wished to resect my stomach for ulcer would have to run much faster than I could! " I am, Sir, yours faithfully, Stoke-on-Trent, June 7th, 1933.

RELAPSE IN PULMONARY TUBERCULOSIS To the Editor of THE LANCET SiR,—Dr. Wingfield’s suggestive communication to the Tuberculosis Association (THE LANCET, June 3rd, p. 1166) provokes further speculation. He attributes relapses in pulmonary tuberculosis largely to allergic hypersensitiveness, but suggests no cause for this. The following considerations will, I think, supply a reasonable explanation. The primitive defences against microbic invasion-inflammation and fever, with the associated blood changes-may be regarded as mainly non-specific ; allergic sensitiveness and the formation of antibodies are largely specific, and result from actual contact with the microbe or its toxins. Antibody formation calls for more coördi- nated expenditure of energy than local allergic sensitiveness, and is likely to come later in an emergency. From experience with tuberculin injections we know that by suitable progressive dosage very large doses are tolerated without either noticeable local or focal allergy, or fever. If, however, the dose is too rapidly increased the allergic response is exces. sive. So long as there is free humoral communication between an active focus in the lungs and the immu- nising organs (largely reticulo-endothelial and blood forming), antibody formation may increase in pro- portion to the increase in toxin formation, so that we may have no marked general symptoms in spite of much circulating toxin-a state of " compensa- tion." If, however, the active focus is insulated by a shield of fibrous tissue or otherwise, toxins may increase in the focus without corresponding anti- body formation. Then if a leak is sprung in the insulating capsule, a large dose of toxin escapes suddenly into circulation and a " flame up " results, because in the absence of sufficient antibody forma- tion there are only the primitive means of defence available-i.e., allergic hypersensitiveness and fever. Dr. Wingfield is disposed to confine the term " relapse " to those cases in which no obvious reason is discoverable. I would suggest that there is always. a reason, even though this is often difficult to find, and that the commonest cause is a breach in the surrounding zone leading to a rather sudden increase in circulating toxin. Such a breach would perhaps be due to unnoticed mechanical causes. Dr. Walther, of Nordrach, used to insist on abstention from active. arm exertion for two years after apparent recovery ; and, excepting for very small lesions, I think it still remains a good rule. Periodical examinations as suggested by Dr. Wingfield would probably make the progressive occupational treatment of convalescents reasonably safe.

RELAPSE IN PULMONARY TUBERCULOSIS

To the Editor of THE LANCET

SiR,—Dr. Wingfield’s suggestive communication tothe Tuberculosis Association (THE LANCET, June 3rd,p. 1166) provokes further speculation. He attributesrelapses in pulmonary tuberculosis largely to allergichypersensitiveness, but suggests no cause for this.The following considerations will, I think, supply areasonable explanation. The primitive defencesagainst microbic invasion-inflammation and fever,with the associated blood changes-may be regardedas mainly non-specific ; allergic sensitiveness and theformation of antibodies are largely specific, andresult from actual contact with the microbe or itstoxins. Antibody formation calls for more coördi-nated expenditure of energy than local allergicsensitiveness, and is likely to come later in an

emergency.From experience with tuberculin injections we

know that by suitable progressive dosage very largedoses are tolerated without either noticeable localor focal allergy, or fever. If, however, the dose istoo rapidly increased the allergic response is exces.sive. So long as there is free humoral communicationbetween an active focus in the lungs and the immu-nising organs (largely reticulo-endothelial and bloodforming), antibody formation may increase in pro-portion to the increase in toxin formation, so thatwe may have no marked general symptoms in spiteof much circulating toxin-a state of " compensa-tion." If, however, the active focus is insulated bya shield of fibrous tissue or otherwise, toxins mayincrease in the focus without corresponding anti-

body formation. Then if a leak is sprung in the

insulating capsule, a large dose of toxin escapessuddenly into circulation and a " flame up

results,because in the absence of sufficient antibody forma-tion there are only the primitive means of defenceavailable-i.e., allergic hypersensitiveness and fever.

Dr. Wingfield is disposed to confine the term" relapse " to those cases in which no obvious reasonis discoverable. I would suggest that there is always.a reason, even though this is often difficult to find,and that the commonest cause is a breach in thesurrounding zone leading to a rather sudden increasein circulating toxin. Such a breach would perhapsbe due to unnoticed mechanical causes. Dr. Walther,of Nordrach, used to insist on abstention from active.arm exertion for two years after apparent recovery ;and, excepting for very small lesions, I think it stillremains a good rule. Periodical examinations as

suggested by Dr. Wingfield would probably make theprogressive occupational treatment of convalescentsreasonably safe. Another safeguard would be

periodical comparison of Mantoux tests with anti-.body tests. Whether, or when, tuberculin treatment.would be advisable in relapse cases would depend onthe response to rest and immobilisation, and someother circumstances.
