valleys, froma one nearly 14,000 feet high to one of 3,000 feet. 
The diurnal variations of temperature on mountain heights, he 
found to be small, rarely more than 12°, and sometimes only 4° 
or 5° ; while in the valleys they were very great, so that com- 
monly the minimum of the night was 30° and sometimes 40° - 
below the maximum of the day. The hygrometric condition of 
the.air corroborated certain of Prof. Daniell’s views. The medi- 
cal application of these inquiries had induced Mr. J. to publish an 
essay, to show among other points, that a removal of a consider- 
able portion of the atmospheric pressure from the surface of the 
human body, must conduce_to the restoration of the function of 
the skin, when exhausted by excess of duty in a tropical climate, 
and sympathy with a debilitated liver. 
Col. Sykes offered some statements on Certain Meteorological 
phenomena in the Ghats of Western India. The correctness of 
the assertion of the annual fall of many feet of rain in certain 
localities of India, having been doubted by many persons, Col. 8. 
had procured the official meteorological records for 1834, kept by 
order of the government of Bombay, at the convalescent station 
of Mahabuleshwar. The observations were taken by Dr. Murray, 
the medical officer in charge at that station. The place is in N. 
lat. 17° 58’ 53”, E. long. 73° 29 50”, near the western scarp of 
the Ghats, or mountain chain extending from Surat to Cape Com- 
Orin. Its elevation is about 4,500 feet. The temperature of a 
Spring is 65.5° FI’, and the mean temperature of the air is nearly 
the same. There is some forest along the Ghats, but in belts 
and patches, so that the wood can have little meteorological effect. 
From the tables it appears, that the mean temperature of 1834 
Was 67.3° F.; that of the hottest month (April,) 74.4°; that 
of the coldest month, (Dec.) 62.3°. The fall of rain was pro- 
digious, amounting to 25 feet 2 inches; and this enormous mass 
_ of water fell almost entirely in the months of June, July, August 
and September. The excessive fall of rain seems not incompat- 
ible with health, for the military detachment stationed at Maha- 
buleshwar is not characterized by any unusual sickness. 
Mr. Follet Osler gave an account of the indications of his ane- 
mometer as observed at Birmingham. He made a detailed state- 
Ment of the changes of the wind about the 19th of November, 
1838, observed at Plymouth and at Birmingham, and concluded 
With some remarks on the great storm of the 6th and 7th of Jan-
