MR. GLAISHER ON THE THERMOM ETRICAL OBSERVATIONS TAKEN AT 
The successive differences shown here between the results at the Apartments of the Royal Society and at the Royal 
Observatory, are harmonious with the differences exhibited in Table XlII. and following remarks, between the tempe- 
ratures of the water of the Thames and those of the air at Greenwich, but of less amount, and they indicate the great 
influence the presence of a tidal river has upon the meteorological elements of the district through which it passes.
