98 Notes on the Frog. [Sess. 
slides, from photographs by Dr Davies, were thrown on the 
screen. These included views of the town of Tenby and the 
surrounding district — Gumfreston, Scotsborough, Pembroke, 
and Lydstep,—besides several views of St Catherine’s Rock and 
its caverns, as well as the Woolhouse Rocks, fishing-boats off 
Tenby, &c. In addition, the marine zoology of Tenby was rep- | 
resented by illustrations of its zoophytes, sponges, starfishes, 
and sea-anemones. Three of the views shown are here repro- 
duced—viz., St Catherine’s Rock; Second Cavern, St Cath- 
erine’s; and the harbour of Tenby.]

Some seem to think that in order to study the habits of an 
animal it is only necessary to confine it in some receptacle — 
where it can be observed now and then as fancy prompts. 
Now I feel sure that is not the proper way to study the 
life-history or natural habits of any creature. Nature must — 
be imitated as nearly as possible, and it is only as this is done 
that a true insight can be got into the life-history and habits 
of any animal. 
Before saying anything about my own observations, I should 
like to read to you a short paragraph from a lesson on tadpoles 
in a certain schoolbook :— 
“TJ went with a tin quart-pot in my hand toe-biter hunting on Clapham 
Common, and brought home exactly a quart of tadpoles ; these I emptied '
