342 IMPROVED SCARIFICATOR. 



inspecting the instrument and working model E, its sim- 

 plicity, I natter myself, will be admitted ; nor is any force 

 of the main-springs spent in overcoming unnecessary fric- 

 tion or ill-directed motion; the ease likewise with which 

 the instrument is discharged, consideriug its strength of 

 spring, will be noticed by every one accustomed to scarifi- 

 cators. It may be objected to this instrument that it is 

 larger and heavier than the ordinary scarificator, but it is 

 capable of being reduced without injury to the improvement, 

 as is shown by the instrument F, which is completely with- 

 in the usual size. 



Testimonies in j have been favoured with testimonies of approbation 

 its favour. 



from the following respectable gentlemen. Dr. Willan, 



physician ; Mr. Armiger, Mr. Frampton, and Mr. Law- 

 rence, surgeons and teachers of anatomy. — It will be also 

 seen, that, while in the possession of Mr. Armiger, it was 

 approved by the late Dr. Rollo, and by Dr. Irwin, the 

 present surgeon-general and inspector of ordnance hospi- 

 tals ; and I may add as a farther proof of its utility, if 

 more be necessary, that by an illiberal use of private confi- 

 dence, others have been made on a similar plan ; and I am 

 misinformed, if the honour of this invention has not been 

 claimed, within these few months, by three or four different 

 individuals. 

 Another scarifi- Accompanying this is another scarificator, G, the peculi, 

 cator t to .^ ct by arity of which consists in the lancets being projeced directly 

 forwards, and returning into the box or case; the working 

 model N is not exactly such as is contained in the instru- 

 ment, but an improvement on it. This instrument and 

 model must be considered merely as experiments, to see how 

 such motion could be effected; for, persuading myself that 

 punctured wounds, would be more painful and more difficult 

 to heal in this, as they are usually in other circumstances, com- 

 pared with incised wounds; and likewise having so happily 

 succeededin constructing that already described, which I con- 

 sider so far superior, I never used it, and therefore can say 

 nothing as to its operative merits ; nor should I have re- 

 called it from oblivion, but having lately seen a description 

 of a scarificator by punctured wounds, invented by a very 



ingenious
