family holiday-but possibility of only obtaining an " attenuated measles after a long a

incubation period " might make the dates more inconvenient. A fellow student of mine, some 30 years ago, developed measles at an awkward time in his medical curriculum, and his father, who was a, doctor, told me he would deliberately expose his children to the infection of such illnesses, if he could have his time over again. Without going as far as this, if I were advising the medical profession with regard to their own children, I should say that the first time a child is exposed to the infection of measles is probably the most convenient and the safest time to have the disease. To prevent that attack, with a short-lived immunity, leaves an added responsibility for the future, and should only be attempted when some exceptional circumstances make measles particularly unfortunate at that season. When a child develops measles in a hospital ward Isero-prophylaxis would be invaluable for the other children, because the administrative responsibilities of measles in a children’s ward are very serious. I am, Sir, yours faithfully, HUGH BARBER. Derby, March 10th, 1930.

To the Editor of THE LANCET. SiB,—I have read with much appreciation the paper by Dr. R. W. Jameson, appearing in your issue for March 8th. I wish strongly to support his contention that the time has come when the distinction between the two forms of small-pox, major and minor, should be officially recognised. As he points out, whilst it may not be easy to decide the nature of the first case in an outbreak it should always be possible to decide after a series of cases have occurred. I believe that no real doubt exists about the nature of any outbreak which has occurred in this country since the war, and it is only in the post-war period that the existence of variola minor as a distinct form of small-pox has been suspected. Dr. Jameson draws attention to the confusion and other disadvantages resulting from the present plan of calling both forms " small-pox," without distinction. We may well ask what value our present casemortality statistics will havein years to come when it will be impossible to know what proportion of the cases lumped together as " small-pox " were of the major or minor variety respectively. The terms "variola major" and " variola minor"have, as Dr. Jameson states, been accepted in the last Decennial International Conference on the Nomenclature of Causes of Death, and I venture to suggest that the Ministry of Health would be moving in the right direction if they invited medical officers of health in reporting small-pox cases to specify whether the cases were major or minor. I am, Sir. yours faithfully, C. KILLICK MILLARD,
