Esophageal echocardiography has been developed for use in patients with chronic obstructive pulmonary disease and is a safe diagnostic procedure which provides high resolution mirror image echoes of many cardiac structures. Conventional anterior and esophageal echocardiograms were performed in 38 subjects. Esophageal echoes were of diagnostic quality in all 38 subjects, anterior echoes were of ...

Remarkable figures showing the decline of smallpox in London during recent years and the heavy cost of treating the disease in the hospitals, were quoted by Dr. W. McConnell Wanklyn, principal Assistant Medical Officer of Health to the London County Council, in a lecture at the London Hospital. In 1921, the lecturer stated, there were 336 cases of smallpox in the country at large, and two cases...

In his Norman Kerr Memorial Lecture on " Drug Addiction " Sir William Willcox said that the commonest cause of addiction in the citizen classes was undoubtedly the prescription of the drug for medical purposes. It was to be feared that after operations drugs were too often given as a routine practice, without sufficient regard to the dangers of toxic action and the development of addiction dise...

of the opinion, formed in 1919, that overfeeding is the one conspicuous sin against physiological law committed in that country. This over-feeding is very general, and often very gross. During the year now closing I have partaken of hospitality, first, in three Northern countries, Denmark, Switzerland and Finland.

Writing in the " Sunday Express " on the Health of 1922, Sir Arthur Griffith-Boscawen says that the recent visitation of smallpox should serve as a warning. " Great Britain, though an island and itself virtually free from smallpox, is in these days of new-fashioned transport in closer touch than ever with overseas countries which have not yet succeeded in stamping out smallpox from their midst....

Pulsed nuclear magnetic resonance techniques with transverse radiofrequency pulses are used to determine the spin-lattice and spin-spin relaxation times of glycerol and Fe solutions of varying concentrations. The nuclear magnetic moments of flourine and hydrogen are found to be μH+ = (1.408± .008)× 10−26 J/T and μF− = (1.324± .007)× 10−26 J/T, respectively. A negative linear relation in log-log...
