ELECTORAL ACADEMY bv THE USEFUL SCIENCES 

 AT EUFURT; 



In the fitting of February the - h, Dr. G. H. Thilow 

 communicated to the Academy an account of fome experi- 

 ments he had made in regard to Galvanifm. Thefe experi- 

 ments were a continuation of hi^ former ones*, and tend 

 'ftill further to confirm the idea that faltpetre pofiefles thd 

 peculiar property of weakening the nervous yftem. Thi3 

 he afcertained by feveral experiments. Having cut off a 

 portion of the crural nerve, which had been laid bare, and 

 Weakened or deprived of Its irritability by faltpetre^ he laid 

 bare another potion towards the knee, and, by ftrewing 

 nitre over it, deprived it in a few minutes of all fufc'eptibility 

 of irritation. '1 lie fame thing always took place as far a9 

 the toes whenever a new porti m of the nerve was laid bare; 

 The author thence concludes t la the vital power is not to- 

 tally extinguifhed even when it cannot be excited by the 

 ftrongeft ftimulants applied to a nerve which has been feveral 

 times fhbje&ft] to the action of fome uinmlant. The heart 

 of a frog laid bare, and ftill in connection with thefurround- 

 ing parts, and which contracted and expanded with great 

 vivacity, b ing ftrewed over with a little faltpetre, its move- 

 ment was by thefe means immediately checked : though the 

 author ha 1 taken the heart from the thorax, the fort-legs cf 

 the animal ftill moved with fuch ftrength, that the whole 

 upper part of the body was the eby agitated from one fide td 

 the other. Some drops of warm milk, let fall between fome 

 of the mufcies and norvess fpeedily put an end to ti ; s violent 

 movement. Thefe linking phenomena the author endea- 

 voured to ; lain from the circumftanccs of milk removing 

 Obit "mate f| and reftoring the equilibrium 



of the mtifcular and nervous fibres. He had obferved alfo,
