supposed that some error had been made in the observations 
or reductions; but the Astronomer Royal has obligingly 
examined the original records, and he finds that all has been 
correctly entered in the printed volume. It is very probable, 
therefore, that the object observed was either a small planet 
having an orbit considerably inclined to the plane of the 
ecliptic, or a variable star which is at present in its phase of 
minimum brightness. 
Mr. Heelis communicated to the Section a notice of an 
old work on the Origin and Nature of Wind, by R. Bohun, 
of New College, Oxon, published at Oxford in 1671, and 
which contains a statement of various points in the law of 
storms, such as their vortical motion, calm centre, change of 
currents, and action upon the barometer, twenty-seven years 
earlier than the earliest account hitherto noticed, which is 
that of Captain Langford, in the Philosophical Transactions 
for 1698. 
Mr. Long exhibited some sketches of the appearances 
lately presented by the disk of Jupiter, and stated that during 
the present apparition of the planet he had not observed any 
dark spots similar to those which were visible last winter.
