greater than the average quantity over the land. On the 17th 

 January, 1850, a tube was placed 1 foot 1 inch deep in a mixture of 

 shingle and earth ; in this a thermometer was placed. The position 

 of the ground was such that scarcely any snow lay upon it, the 

 constant strong winds removing it almost as soon as deposited. 

 Column 4 gives the register . of this thermometer. February 

 12th, 1859, a tube was placed horizontally on the surface of the 

 ground beneath the snow lying over the place where thermo- 

 meter No. 1 was sunk, and the temperature as shown by this 

 thermometer (Column 5) was registered until all the snow dis- 

 appeared. Column 6 gives the mean temperature of the air 

 for the day on which the registers of the different thermometers 

 were taken. Column 7 gives the mean temperature of the air 

 for the number of days or hours intervening between the register- 

 ing of the thermometers. 



All the registers of the different thermometers are corrected so 

 as to reduce them to that of the standard.

The following enumeration comprises all the species collected by 

 Dr. J. D. Hooker in the Himalaya, and in conjunction with Dr. 

 Thomson in the Khasia Mountains, as well as those gathered in 

 Ceylon by the late Dr. Gardner and Mr. Thwaites, and includes
