that it is more proper to confecrate the names of men who 

 liave enriched them by their difcoveries, than thole of tlie fa- 

 bulous deities, and great men who refemble thefe deities in a 

 great many points, C. Sage wiflied that the name of nraniuni. 

 given to this metal by the Germans, who call the planet dii- 

 covered by Herfchel Uranus, might be changed. In ap- 

 plauding thefe motives, it will perhaps be found that the 

 names of celebrated men ought to be affigned to thofe things 

 which have been the particular objeiSs of their attention, 

 and that Klaproih, who difcovered this metal, has a greater 

 right than any other to dillinguifli it by his name. 7'he 

 French feem conftantly to agree in giving the name of 

 Herfchel to the planet which he brought from that obfcurity 

 under which it li.id been concealed for fo many ages; and, 

 by the cffeft of the fame fentiment of juftice, the names of 

 Piazzi and Olbers will undoubtedly remain to thofe difco- 

 vered by thefe aftronomers. 



Zoologifts and botanifts now confecrate to their mafters 

 and friends the genera or fpecies which they difcover; and 

 niineralogifts no doubt w ill foon follow their example. The 

 name of Schcele, fo juftly celebrated, has already been fubtUf 

 tuted for that of tungjkn. 



ANATOMV. 



Artificial Vreparat'i07is in U'ax. 



The art of Imitating anatomical preparations with wax, of 

 little ufe when applied to objefts eafy to be obiained bv dif- 

 feftion, and which may be daily procured, fuch as thofe of 

 the moft vifible parts of the human body, becomes import- 

 ant when applied to the reprefentation of things rare or diffi- 

 cult to be obtained, fuch as the different objecls of compa- 

 rative anatomy, or of things accidental and tranfienl, as 

 monftrolities and unconnnon difcafes. In the Ia(l place, it 

 is alnioft indif|)enfable to make known to pupils certain parts 

 of fuch a complex nature, that the demonltralor cannot de- 

 velop the whole in one difledlion. 



It is to this lad clafs that we muft refer the lymphatic 

 vcfTels. The fucccfs of inje6ling them is fo variable ; the 

 quickfilver emi)loyed for that purpofe is fo inconvenient, in 

 confecjuence of the fluidity it retains; in a word, it is fo rare 

 that it can be made to penetrate to the lafl; ramifications of 

 thefe vcflels, even in one limb, that it is o«ily by repeating 

 thefe operations for a long time, and on a great number of
