The only thoroughly safe deer is a dead one; for even does can do mischief. A SAMPLE OF NERVOUS TEMPERAMENT. As an example of temperament in small carnivores, we will cite the coati mundi of South America. It is one of the most nervous and restless animals we know. An individual of sanguine temperament rarely is seen. Out of about forty specimens with which we have been well acquainted, I do not recall one that was as quiet and phlegmatic as the raccoon, the nearest relative of _Nasua_. With a disposition so restless and enterprising, and with such vigor of body and mind, I count it strange that the genus _Nasua_ has not spread all over our south-eastern states, where it is surely fitted to exist in a state of nature even more successfully than the raccoon or opossum. The temper of the coati mundi is essentially quarrelsome and aggressive. While young, they are reasonably peaceful, but when they reach adult age, they become aggressive, and quarrels are frequent. Separations then are very necessary, and it is rare indeed that more than two adult individuals can be caged together. Even when two only are kept together, quarrels and shrill squealings are frequent. But they seldom hurt each other. The coati is not a treacherous animal, it is not given to lying in wait to make a covert attack from ambush, and being almost constantly on the move, it is a good show animal. THE STRANGE COMBATIVE TEMPERAMENT OF THE GUANACO. In appearance the guanaco is the personification of gentleness. Its placid countenance indicates no guile, nor means of offense. Its lustrous gazelle-like eyes, and its soft, woolly fleece suggest softness of disposition. But in reality no animal is more deceptive. In a wild state amongst its own kind, or in captivity,--no matter how considerately treated,--it is a quarrelsome and at times intractable animal. "A pair of wild guanacos can often be seen or heard engaged in desperate combat, biting and tearing, and rolling over one another on the ground, uttering their gurgling, bubbling cries of rage. Of a pair so engaged, I shot one whose tail had then been bitten off in the encounter. In confinement, the guanaco charges one with his chest, or rears up on his hind legs to strike one with his fore-feet, besides biting and spitting up the contents of the stomach."--Richard Crawshay in "The Birds of Terra del Fuego." MENTAL TRAITS AND TEMPER OF THE ATLANTIC WALRUS Mr. Langdon Gibson, of Schenectady, kindly wrote out for me the following highly interesting observations on a remarkable arctic animal with which we are but slightly acquainted:
