It seems certainly rather curious that Dr. Riviere should allege that Abrams’s areas bear no relationship to his in position, size, shape, &c., even in regard to those small areas described by Abrams which are known to Dr. Riviere. With regard to the posterior band of dullness described by Dr. Riviere, as a matter of fact, Abrams’s posterior circles are placed just over the angles of the scapulas, and it would be rather a difficult feat to locate them much nearer to certain of Dr. Riviere’s shadings, while as regards that portion of the band described by the latter from about the fifth to the seventh dorsal spines, Abrams has the following statement :It must be recalled, however, that the region correspond-
A GREEN BACKGROUND FOR THE OPERATION AREA. To the Editor of THE LANCET.
SIR,-Sir Berkeley Moynihan’s letter to THE LANCET of Sept. 18th, in which he advocates the use of green towels, interests me very much since I have used for the past five or six years pale-blue towels for operations in private. My object was not to rest the eyesight, although I agree with Sir Berkeley Moynihan that white towels certainly make the operation wound relatively darker. To realise this, one has only to recall a cystoscopy in a sunlit bedroom with a bad blind-a very feeble affair. My aim, however, was a very practical one-to distinguish at a glance between my own sterilised towels and those of other people, of which there is always a profusion in private houses before operaand none of which one ever uses. I found tions, ing to the fifth dorsal vertebra is normally dull, the dullness further that the blue colour had on strange for a short distance on either side.3 extending nurses a distinctly inhibitory effect and kept This, together with the circular areas just alluded unsterilised people away from the operation area. to, pretty well fulfil Dr. Riviere’s conditions. One’s instructions to unsterilised assistants (whose Dr. Riviere seems anxious to separate the reflex in their proper capacity is often more of contraction from the atelectatic zones. But it help valuable than that of sterilised ones in private) are is impossible to do so. The dull areas described so simple-to "avoid anything blue." The only by Dr. Riviere are in fact " atelectatic " zones, and forcible criticism one can make of blue or green this particular form of atelectasis appears, under towels is that nurses who have had to wash them all circumstances, to be due to the action of the at night say they look darker, and it is a little reflex in question.

THE LANCET of July 24th on the subject of scorpion I would first of all draw attention to the letter of stings, and note that he suggests treatment by Dr. D. Walsh in THE LANCET of May 10th, 1913, permanganate of potash. From personal experience concerning the treatment of typhoid fever by tincI can endorse the statement that the pain caused ture of iodine. the late South African War by a scorpion sting is severe.

Again trying it driven into the affected part, and in addition the same war in other cases I noticed that there is the feeling that electricity is being dis- during of this remedy was not so favourable by the effect charged from the needle into the tissues.
