Abstract
LONDON. Royal Society, November 18.—W. S. Patton and E. Hindle: Reports from the Royal Society's Kala Azar Commission in China.—R. Hill: The chemical nature of hsemochromogen and its carbon monoxide compound. The haemochromogen type of spectrum shown by compounds of haematoporphyrin with metals other than iron is not due to the presence of nitrogen compounds. It is suggested that the property of forming haimochromogens is limited to the iron-porphyrin compounds. Two molecules of pyri-din are necessary to convert reduced haematin into the corresponding hasmochromogen. Carbon monoxide haemochromogen has one molecule of pyridin in combination when produced in the presence of the latter. The carbon monoxide compounds of reduced haematin and pyridin haemochromogen both contain one molecule of carbon monoxide.—H. Gremels and R. Bodo: The excretion of uric acid by the kidney.—C. H.
