The plants absorbe the carbonic acid gast evolved by
animal life - convert the carbon to the material of this growth -
(assimilation) and give back the pure life invigorating oxigen -

By this arrangement we have no occasion either to "feed the
animals" or change the water merely supply the loss by evaporation.
I have six or seven species of frogs and two species of Salamander - but
by far the object of the greatest interest to me is the tadpoles
of the Salamander lureda (Sager) - I shall be able to give a
complete history of the habits - food, mode of reproduction, embryonic
changes of this interesting reptile - As this is the largest north
america Salamander a faithful record of the tadpole metamorphosis
cannot fail to be of the greatest interest to science -

I have made and are still making a full Suit of drawing
and painting of their changes -

I have a number of living T. Mandingii in proper quarters and I
hope to record something about them not yet know -

Am in the Gray Gopher - (Spurmopheler Franklinii) line got lots - have
one for a pet - an interesting chap - a perfect grahamiti - never tastes
flesh - more like the wood chuck (Arctonus Monax) than the
Strapur Gopher -

Who told you that the little Striper Hyler was (H triceriata)?
