known to affect the central nervous system. The serumof a patient who had recovered in 1933 from louping-illgave positive complement-fixation and neutralisationtests with’the viruses of both louping-ill and Russianspring-summer encephalitis, as did the serum of a
patient who had an encephalitic illness while workingwith the two viruses in the laboratory. There is therefore,according to Casels and Webster, a striking similaritybetween the two viruses in their clinical effects, modesof transmission, and immunological responses.
SUMMARY
Two cases of louping-ill in man are reported, withevidence suggesting that the infection was acquirednaturally and not in the laboratory as in previous cases.The clinical picture of louping-ill in man is that of
meningo-encephalitis, usually following a prodromalinfluenza-like illness and followed by complete recoveryin most cases.
i It is suggested that the illness would be more oftendiagnosed if it were suspected whenever a meningo-encephalitis appears in a person exposed to louping-illvirus.The evidence linking louping-ill with Russian spring-
summer encephalitis is given.The credit for diagnosis in case I lies essentially with the
patient, Mr. William Lyle Stewart, of the Department of
Agriculture, King’s College, Newcastle-on-Tyne. To him weare indebted also for a clear history of his symptoms, foradvice on how the diagnosis could be established, and forsources of further information.lhanks are also due to Dr. W. S. Walton, medical officer of
health for Newcastle-upon-Tyne, and to Dr. George Hurrelland Dr. E. G. Brewis, medical superintendents of theNewcastle General Hospital and the City Hospital for Infec-tious Diseases respectively, for facilities provided ; Dr. R.Norton and Dr. Emslie Smith for bacteriology ; Mr. G. F.Rowbotham for neurosurgical advice ; Dr. S. WhatelyDavidson for radiological reports ; Dr. W. H. H. Merivalefor biochemistry ; Dr. Paul Szekely for helping one of us(G. D.) with translation of the literature ; and Dr. T. H.Bates, Dr. L. Richmond, and Dr. G. W. L. Kirk for referenceof the patients and information given.

LEONTIASIS OSSIUM

WITH the improvements that have taken place in
dentistry and in the surgery of the nasal accessory sinuses,cases of leontiasis ossium should become rare. The skullfrom the case reported here has been accepted by themuseum of the Royal College of Surgeons.The patient was a spinster, who died in 1944 at the age of
73. Her appearance and health were normal until the ageof 20, when she had a bicuspid tooth stopped. She had nopain, but a few months afterwards a hard swelling developedin the gum above the tooth, followed later by similar changesin the cheek. Much dental treatment followed, but theswelling steadily increased, spreading to the other cheek andinto the frontal region. Beyond occasional headaches thecondition caused her no physical or social inconvenience.She was a charming, witty, and well-beloved lady whocontinued her work as-a book-keeper until four months beforeher death, with only one short period of ill health.
In 1939 she had a transient hemiplegia : blood-
pressure 220/95 mm. Hg; left knee-jerk exaggeratedand left plantar reflex extensor; otherwise no physicalsigns. She was working again in six weeks, the left

COMMENTS
In view of the hyperpiesia, it can be fairly said that thecondition caused little inconvenience to her health andwas only slightly contributory to her death.The history appears to follow the usual lines in that a
chronic septic osteoperiostitis follows a sinus infectionand one by one the accessory air chambers are filled withmasses of inflammatory cancellous bone protruding out-wards and causing great disfigurement. Bony changesspread to the skull (cancellous hyperostosis of Virchow) ;the mandible sometimes is involved, but the base of theskull usually escapes. In the present case, however, thebase is involved and the mandible is normal. The lion-like head is well depicted in the photograph. The absence ofcolds and the dryness of the nose suggest that the mucosalining the sinuses is the major source of nasal secretion.
" ... Can there be values greater than the mere attainmentof health ? One reason why we have not been more successfulin directing people toward healthful living is that sub-
consciously many have decided, and quite correctly, thatthere are more important things than merely being healthy."- W. W. BAUER, M.D., director, bureau of health education,American Medical Association, in Motivation in HealthEducation. London, 1948 ; p. 20.
