The ufe of trituration, in promoting the powers of 
folution, is evident from Experiments IV. VI. an d 
VII. and would have been ftill more fo, if a proper 
apparatus had been employed. The Count de la 
Garaye, a French gentleman, who is diftinguifhed for 
his afiiduity in applying the different branches of 
philosophy to the improvement of medicine, has 
defcribed a very convenient machine j and pointed 
out an admirable procefs for obtaining from veoeta- 
bles, by triture with- water, the matters in which 
their virtues chiefly refide. The contrivance is ex- 
tremely Ample, confiding only of a veffel, to which a 
churning ftaff is fitted, which, by means of a wheel, 
and a cord, is perpetually whirled round with a rota- 
tory motion. By this confiant agitation, the mod 
accurate diffufion is produced ; and different portions 
of the menftrua are in quick fucceffion applied to 
every part of the fol vend. 
From the Vth Experiment, no certain conclufibns 
can be deduced y except that the extra# is a much 
weaker preparation than is commonly fuppofech It is 
liable to all the objections, which have been advanced:
