With regard to the fossil plants ot the Tabbowa beds, we may 
count ourselves very fortunate, in that Professor Seward, of 
Cambridg2, has kindly consented to deal with them. His 
pronouncements will be awaited with interest. The writer’s 
tentative opinion was that the Tabbowa plants belonged to 
the Glossopteris or some other closely related flora. If this 
view proves correct, it must follow that the beds containing

continent (Gondwanaland), which, according to Stiess and his 
followers, extended from Brazil on the west to Australia on 
the east, and included parts of Africa and India.

had been crushed by blows from a stick. 
The snake, its mouth full of blood and eyes protruding from 
their sockets, showed no signs of life. It was a fine specimen,

it in a cage to see if the snake would survive its injuries. 
For some days the tic-polonga showed no signs of life, 
though there was no smell of putrefaction, a sure sign that 
death had not occurred. Notwithstanding this, I had to 
wait three or four weeks before I could detect definite signs
