From the dismissal of the scientific professors from the University of Salamanca by Ferdinand VII. of Spain, in the beginning of this century, down to sundry dealings with scientific men in our own land and time, we see the same war continued.

THE kangaroos have now become familiar objects to all who visit our Zoölogical Gardens, or who are familiar with any considerable zoölogical museum.

Their general external form, when seen in the attitude they habitually assume when grazing (with their front limbs touching the ground),
