We (hall have to report alfo fome conftderable improve- 

 tn en ts in medicine from the ufe of new, or little known re- 

 medies. Will you allow me to mention, that I mould be 

 glad to engage with an active and ardent young enquirer, 

 who has already fome readinefs in common chemical procefles. 

 His employment would be in researches, connected with 

 medicine and phyfiology. If fuch a perfon, refident in Lon- 

 -don, mould be induced fyy this notice to inquire, he might 

 obtain fome previous, fatisfa&ory information from Mr. Davy 

 at. the Royal Inftitution.

On the Quantity of Nutriment to be obtained from various Kinds

!>rouft on im- IVlR. PROUST, profeflbr of chemiftry at Madrid, has pub- 



fiftIn«of e th^ b " IImed a work ' intitIed an Inquiry into the Means of Improv- 

 ibJdicr. ing the Subfiftence of the Soldier. The following is a fum- 



mary of what it contains of mod importance, and of general 

 utility* 

 Jdly fsom bones. ** nas l° n g been known, that a very agreeable and nutri- 

 tious fq/&d might be procured from bones : a food particularly 

 recommended as a reftorative under the name of hartfhorn 

 jelly, which is in fa£i procured by boiling (havings of bones, 

 the common hartlhorn (havings of the mops. All that is want- 

 ing, is a cheap and ealy mode of procuring this jelly in fuffi-> 

 cient quantity from a fubftance now commonly thrown away ; 

 for bones after they come out of the pot are as good for the 

 purpofe, and nearly as productive, as frefh bones. The 

 (havings are too dear. Papin's digefter, which has been em* 

 ployed, is a machine too expenfive for the poor, too dange- 

 rous for common ufe^nd apt to give the jelly a burned 

 tafte.
