ities, so too, is Rolf not a solitary example among dogs of his
kind to profit by instruction. Indeed, many of his descendants are
receiving tuition under the guidance of different instructors, and are
giving a good account of themselves.

I will here add Professor Ziegler's Report:

"NEW REPORTS CONCERNING THE CALCULATING AND SPELLING DOG[6]

"_By Professor Ziegler_

"The descendants of the dog Rolf that have been trained by Frau Dr.
Moekel,[7] are now full grown, and several of them have acquitted
themselves with success. These are the bitch Ilse, the two males, Heinz
and Harras, and the bitch Lola, and I here purpose to set down the
latest information about these animals. It is of great importance that
the various persons under whose care these dogs were trained
should--though independently of each other--have made similar
observations. All investigators have reported the same astonishing
memory, this affording the foundation for the dogs' feats in reckoning
and spelling.

[6] Taken from the "Communications of The Society for Animal
Psychology," 1916. pp. 6-9.

"As these reports come from persons resident at different places, who
neither know, nor are in communication with each other, we here have
the surest proof there is no secret or trick involved in the matter."

"A. REPORT ON THE BITCH ILSE

"Concerning Ilse, of whom a clergyman is the owner, Dr. Oelhausen has
already given us some details in earlier numbers of our
'Communications'.[7] He now sends me the following, which he received
from Frau Dr. Moekel in the summer of last year. The reverend gentleman
had left Ilse for a few hours at Frau Dr. Moekel's--as he had often
done before--while he went into town to make some purchases. On this
particular occasion Frau Dr. Moekel noticed that Ilse looked
particularly depressed, and her little daughter, Carla, being disturbed
about the dog's woe-begone air, said: 'Mummy, Ilse must be in trouble!
Only see how serious she is!' So Frau Dr. Moekel asked the dog: 'Ilse,
are you really sorrowful?' To which Ilse responded: 'Ja, hr hib.' ( =
yes, Master beating!). Frau Dr. Moekel: 'But Ilse, I am sure your
master is kind to you; you are imagining!'

[7] These dogs were born on 26 and 27 January, 1914. Compare the
letter of Rolf in the "Communications of the Society for Animal
Psychology," 1914, p. 28; and "The Soul of the Animal," p. 111.
