the mental effort would become more largely developed, and 

 hence a permanent increase of mental power be obtained. Tliis 

 reasoning is in accordance with the known laws of the physi- 

 ology of the nei-vous system, and is fraught with the most 

 important results. We may refer the reader interested in the 

 subject to the masterly little work of Doctor Verity, ' Change 

 produced in the Nervous System by Civilization.' After this 

 introduction, M. Ldonard spoke to his dogs in French, in his 

 usual tone, and ordered one of them to walk, the other to lie 

 down, to run, to gallop, halt, crouch, &c., which they performed 

 as promptly and correctly as the most docile children. Then 

 he directed them to go through the usual exercises of the 

 manet/e, which they performed as well as the best-trained ponies 

 at Astley's. He next placed six cards of different colours on 

 the floor, and, sitting with his back to the dogs, directed one to 

 pick up the blue card, and the other the white, &c., varying his 

 orders rapidly, and speaking in such a manner that it was 

 impossible the dogs could have executed his commands if 

 they had not a perfect knowledge of the words. For instance, 

 M. Ldonard said, 'Philax, take the red card and give it to 

 Brao ; and Brae, take the white card and give it to Philax.' 

 The dogs instantly did this, and exchanged cards with each 

 other. He then said, ' Philax, put your card on the green ; 

 and Brao, put yours on the blue,' and this was instantly per- 

 formed. Pieces of bread and meat were placed on the floor, 

 with figured cards, and a variety of directions were given to the 

 dogs, so as to put their intelHgence and obedience to a severe 

 test. They brought the meat, bread, or cards, as commanded, 

 but did not attempt to eat or to touch, unless ordered. Philar 

 was then ordered to bring a piece of meat and give it to Brae, 

 and then Brae was told to give it back to Philax, who was to 

 return it to its place. Philax was next told he might bring a 

 piece of bread and eat it ; but, before he had time to swallow 

 it, his master forebade him, and directed him to show that he 

 had not disobeyed, and the dog instantly protruded the crust 

 between his lips." 



This, however, was not the most curious of the performances 

 of the wonderful animals. The account proceeds — " Presently: 

 M. Leonard invited a gentleman to play a game of dominoes 

 with one of the animals. The younger and slighter dog then 

 seated himself on a chaii- at the table, and the writer and 

 M. Leonard seated themselves opposite. Six dominoes were 

 placed on their edges in the usual manner before the dog, and
