I have been speculating last night what makes a man a discoverer of undiscovered things. As far as I can conjecture the art consists in habitually searching for the causes and meaning of everything which occurs.

I am a firm believer, that without speculation there is no good and original observation.

The season of love is that of battle. The roots of these fights run deep.

A fair result can be obtained only by fully stating and balancing the facts and arguments on both sides of each question." Charles Darwin

It is scarcely possible to doubt that the love of man has become instinctive in the dog.

The lower animals, like man, manifestly feel pleasure and pain, happiness and misery. Happiness is never better exhibited than by young animals, such as puppies, kittens, lambs, &c., when playing together, like our own children.

Much love much trial, but what an utter desert is life without love.
