r ability to count. I have known a monkey that
could count to five. He played with a number of marbles, and I would ask
for two marbles, one marble, four marbles, as the case might be, and he
would quickly hand the number requested.

Another incident that will illustrate the point is the case of a mule
owned by an old negro near Huntsville, Texas. The regular routine work
of this mule was to cart two loads of wood to the town every day. One
day the negro wished to make a third trip, but was unable to do so. When
asked the reason, he replied, "Dat fool mule, Napoleon, done decided we
had hauled enough wood fo' one day!"

Prantl claims that the time-sense is totally absent in animals, and that
it belongs only to man, as one of the attributes of his mental
superiority. However, many facts go to show that animals have not only a
specific time-sense, but also a sense of personal identity which reaches
back into the past.

Time-sense is very highly developed in dogs, cats, hogs, horses, goats,
and sheep. They apparently are able to keep an accurate account of the
days of the week and hours of the day and night, and even seem to know
something of numerical succession and logical sequence. A friend in
Texas had an old coloured servant, whose faithful dog had been trained
to know that just at noon each day he was expected to carry lunch to his
master. I have seen the dog on more than one occasion playing with
children in the streets, suddenly break away without any one calling
him, or any suggestion on our part as to the time, and rush for the
kitchen just at the proper moment. No one could detain him from his
duty. This same dog, however, would on Sundays continue to play at the
noon hour. Surely, if any explanation is to be offered in such a case as
this, it will imply as strict a sense of time as it does of duty.

A friend relates a case of a dog that went each evening to meet a train
on which his master returned from the city. On one occasion the train
was delayed two hours, and it was exceedingly cold, but the devoted
companion remained until his master arrived. Innumerable instances of
such all-absorbing affection, showing at the same time a sense of time,
might be cited.

Dr. Brown gives a most remarkable example of a dog's ability to
distinguish time. The story is of a female dog, though named Wylie,
which was purchased by Dr. Brown when he was a young man, from an old
shepherd who had long been in his employment. W
