under his throat, the middle finger and the thumb gently 

 pressing the bones ot" his shoulders, while my right was pass- 

 ing along his back. Replacing the animal in his situation, I . 

 carefully repeated the action, and found my hypothesis to be 

 correct ; as I received at short intervals a disagreeable sensa- 

 tipn in the left hand and arm, exactly resembling a slight 

 shock from the Leyden phial, the body of the animal with 

 my arms and back forming the electric circle. Afterwards, 

 changing the position of the creature and placing my right 

 hand under his throat, while I passed the left along his back, 

 I experienced a similar sensation in the right hand. On trial, 

 some friends who were present found the same result. I 

 have repeated the experiment, and, the present state of the 

 atpiosphere being favourable, always with the same result — > 

 provided the cat had lain some time before the fire. 



If the object of this trifling communication be not generally 

 known, perha)is the publishing of it will serve to amuse your 

 readers, and add to our stock of philosophical curiusiiies. 

 I remain, gentlemen, 



Your obedient servant,

P. S. It is not indispensably necessary that the finger and 

 thumb be placed on the shoulders : the bone of the jaw has 

 the same effect. 



ERROR IN TABLES OF ABERRATION, ETC. 



I®° We are requested by Mr. F. Baily to correct an error 

 which appears in No. 294 of our Journal, in the account of 

 the New Tables of Aberration and Nutation. It was there stated

 The table of the constant quantities (denoted by a, b, c, d, and 

 of, b', c',d',) were computed by Dr. Ursin and Mr. Hansen, 

 under the immediate direction of the celebrated M. Schu- 

 macher, so well known foi" his zeal and abilities in the cause 

 of science, and equal])' distinguished for his liberal views in 

 promoting and widely extending the diffiision of knowledge.
