The following extracts have been placed at the disposal of the 
Society at the urgent request of the Secretary, because he fully 
appreciates the value of original observations so clearly and naturally 
expressed, and because he hopes that the appearance of this record 
of them will induce corresponding members of the Society in other 
parts of the world to occupy themselves in a similar manner.
