"'The astonishment of the audience increased with every moment, while their delight and enthusiasm at the close of this remarkable and interesting evening found vent in a storm of applause.'
"Another journal, the 'Badische General Anzeige' wrote:
"'The evening's performance must have converted many who before had been sceptical.'"
Even as there are numerous horses capable of exercising similar abilities, 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.
"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."
