Gafcous Oxyd of Azof. l8j 



C. Loifel, aflbciate, has publifticd a complete treatifc on 

 all the procefles in regard to the art of glafs-making. 



C. Sabbalier has Ihown, that it is often poffible to fave 

 thofe who have the upper part of the arm ihaitered, or the 

 head and neck of the humerus attacked with caries or ex- 

 ollofis, from the cruel and dangerous operation of antputating 

 that limb at the joint, that is to fay, at the place wliere it is 

 joined to the Ihoulder, liierely by extirpating the upper part 

 of the bone. Several perfons treated according to this me- 

 thod have experienced no fenfiblc decreafe in their Itrenglli 

 or the mobiUty of the arm. 



GASEOUS OXVD OF AZOT. 



We have already had occafion to ir.cntion the refalt of 

 fome experiments made at the Medic?! i^neumatic Ir.ititu- 

 tion, Briftol, with lliis new gas, ai-;d ih.c hopes thefe afforded 

 that it would prove a powerful remedy for various di;eafes. 

 The follow ing extract of a letter, with which we have been 

 favoured from Dr. Beddoes, gives fome forther information 

 on this fubjecl, that cannot fail to prove interefting to our 

 philofophical readers: — 



*' SIR, 



** I am fure it will give you plcafure to hear that the gas 

 which you noticed in your Magazine has fully maintained 

 its charafter. The inference I could not fail to draw from 

 the firft effefts, with regard to its power in curing palfv, has 

 turned out juft. You will undoubtedly believe that I do not 

 mean to affirm that it will prove an infallible remedy in pa- 

 ralytic complaints ; but in the mofl: inveterate cafes of hemi- 

 plegia, originating in apopleclic feizures and confirmed by 

 repeated ftrokes, it has reftored feeling and the power of vo- 

 luntary motion to the afFeiSled fide; and I am perfuadcd it 

 will continue to do as much in a large proportion of in- 

 ftances. The full details will be given in a work by Mr. 

 ]^avy and myfclf, now in the prefs. No untoward accident 

 has occurred in the many hundred trials lately made with 

 the gas : but a few hvfterical females having cautioufiy re- 

 fpircd it, there has been reafon to think that a larger dofe 

 would have given rife to fits, as fiatcd in mv Notice."
