such a distance as to receive the smoke. 

 Being well covered with lamp-black, this 

 is brushed off and collected on paper. It 

 is then well mixed in a mortar with a so- 

 lution of gum or gluten, and then reduced 

 to the consistence of paste ; it is then put 

 into little moulds, where it receives those 

 shapes and impressions with which it 

 comes to this country. It is occasionally 

 manufactured in a great variety of forms 

 and sizes, and stamped with ornamental 

 devices, eitiier plain or in gold, and vari- 

 ous colours.

An iso/netrical mode of drawing, con- 

 sists in making all the rij,ht angles of a 

 cube or other figure, on a plane at 60° or 

 120°. The sight of" a person viewing it, 

 meets the vertical and horizontal parts at 

 the same angle. This mode of (h"a\ving 

 is well calculated for describing machi- 

 nery; the eye is supposed to be at an infi- 

 nite distance; sometimes called mililary 

 persjjective. 



Charcoal chalks for drawing. — Saw 

 the finest charcoal into slips of the size 

 wanted, and put them into a vessel of 

 melted bees-wax; put them near a slow 

 fire for half an hour; take them out, and 

 when they are perfectly cool, they are fit 

 for use. The advantages of these pencils 

 are, (it is said) that they can be made at 

 the most trifling expense, and the draw- 

 ings made with them are as permanent as 

 ink. 



The above process will harden both red 

 and black chalks, and also make them 

 permanent.

Extract from an experimental inquiry 

 . into the Laws of Vital Functions-, 



with some observalioyu on the Nature 



and Treatment of Internal Diseases.

He says " I cannot help regarding it as 

 almost ascertained, that in those diseases 

 in which the derangement is in the ner- 

 vous power alone, where the sensorial 



functions are entire, and the vessels 

 hcaltliy, and merely the power of secre- 

 tion, which seems immediately to depend 

 on the nervous system, is in fault, galvan- 

 ism will often prove a valuable means of 

 relief." 



OF ASTHMA AND DYSPEPSIA. 



The following observations relate chief- 

 ly to affections of the lungs: 



Of Ihe effects of galvanism in Dyspepsia, 

 the principal experience which I have yet 

 had has been in cases where it was com- 

 plicated witii asthmatic breatliing. When 

 the etl'ect of depriving the lungs of a con- 

 siderable part of the nervous influence is 

 carefully attended to, it will be found, I 

 think, in all respects similar to a common 

 disease, which may be called habitual 

 asthma; in which the breathing is con- 

 stantly oppressed; better and worse at dif- 

 ferent times, but never free, and often 

 continues to get worse in defiance of every 

 means we can employ, till the patient is 

 permanently unfitted for all the active 

 duties of life. The animal in the above 

 experiment, is notaffectetl with the croak- 

 ing noise and violent agitation, which 

 generally characterize fits cf spasmodic 

 asthma. This state we cannot induce arti- 

 ficially, except by means which lessen the 

 aperture of the glotis. We have seen 

 from repeated trials, that both the oppres- 

 sed breathing and the collection of i)hlegm, 

 caused by the division of the eighth pair 

 of nerves, may be prevented, by sending 

 a stream of galvai'.ism through the lungs. 

 That this may be done with safety in the 

 human bod}', we know from numberless 

 instances, in which galvanism has been 

 applied to it in every possible way. 



Such are the circumstances which led 

 me to expect relief from galvanism in ha- 

 bitual asthma. It is because that expecta- 

 tion has not been disappointed, that I trou- 

 ble the reader with the following account 

 of its effects: 



Although the effects of galvanism in 

 habitual asthma have been witnessed by 

 many other medical men, I have mention- 

 ed nothing in the following pages which 

 did not come under my own observa- 

 tion. 



I have employed galvanism in many 

 cases of habitual asthma, and almost uni- 

 formly with relief. The time, during 

 which the galvanism was applied, before
