that a living specimen of the Moa has been found, Miss Herrick 
is under a mistake. But a more important error is the assertion 
that “ a development in one direction is invariably accompame 
by a correlative development in another.” Fossils have been 
found whose dentition and extremities would respectively assign 
them to widely different places in the Animal Kingdom. 
A very curious fadt is mentioned in the account ot the 
pitcher-plants. A species of moth, Xanthoptera semicrocea, both 
in the adult and the larval state, possesses peculiarities _ which 
enable it to overcome the dangers encountered by other insects 
in the tubes of Saracenia. . 
In the following chapter, devoted to the more typically carni- 
vorous plants, the author returns to Darwin, and prefaces an 
acknowledgment of the treasures of fadt which he has given to 
the world with the words “however strongly we may and do 
dissent from his conclusions taken as a whole.” This judgment 
is not very different from that which we must pass upon the work 
before us. As a statement of fadts we can and do recommend 
it, but its theoretical portions are certainly not on a level with 
the science of the day, or in harmony with what we believe to 
be the truth.

This number contains a “New Theory of Sun-spots, by Mr. R. 
A Proaor. The author holds that the spots are regions of 
cooling and not of greater heat, and are probably due to the 
aaion of forces working from within expansively. If this view 
is correa a season of sun-spots must be a season of diminished 
heat radiation from the sun, and we on earth — and the denizens, 
if any, of the other planets— must suffer from cold. 
If below the luminous surface of the sun there are regions of 
darkness, we may ask how does this faa agree with the nebulai 
hypothesis ? If the sun has been formed by the gradual con- 
densation of a “ fire-mist,” surely its interior should be the 
hottest portion, or at any rate not the coldest. _ 
It is further recorded here that on a certain occasion there was 
observed “ an ejedtion of matter, solid or liquid (or if vaporous, 
then of great density), at velocities so great that the ejedted 
matter could never return to the sun. . . . . In this case the 
ejedted matter is now travelling, with velocity constantly dimi- 
nishing, but never to be entirely lost, into the depths of inter- 
stellar space.” . . , 
If the sun is thus in the habit of squandering his substance,
