sources than the privation of that fame 
and those honours in the gift of their 
countrymen ; and those who in modern 
days have been driven sto foreign 
shores, haye always cherished: fond 
recollections of their own soil. In 
spite of the admonitions or the argu- 
ments of a science, which in its view 
soars above the prejudices. of our na-

~ SIR, 
MOST sincerely regret that I have 
lately oceupied so considerable a 
portion of your nseful pages; but, 
trusting to your love of practical sci- 
ence, I once more, and I hope for the 
last time on the subject in question, 
venture on your indulgence by a few 
observations in answer to the kind 
suggestions of J. S. H. at page 33 of 
your number for August, whose friendly 
hints I should consider it as ingratitude 
absolutely to neglect; however, for the 
aboye reason, I hope J. S. H. will 
excuse my brevity. Fig. 1, page 33, is 
a more portable form of the instrument; 
but, in the present case, I do not per- 
ceive that it would on that account be 
more “‘ converient.” After all, when 
prepared for use, it puts on nearly the 
same shape as the one originally con- 
structed by me. Fig. 2 is most de- 
eidedly of an elegant shape; and, 
were it practicable, ougut to be pre. 
ferred for beauty of design to any other 
perhaps which could he adeptec. 
When I invented my first instrement, 
many plans and forms of the outward 
figure were under trial an¢ considera- 
tion; and, in this wey, an ingenious 
artizan whom I employed, wasted a 
great deal of time, lavovr, and materi- 
als, to litle putpose, for theories are 
too often found incompatible with ac- 
tual experience. Fig. 2 requires to 
be fashioned on a solid block or model; 
and this implies, that it must be com- 
posed of a great number of slips of thin 
fir, which consequently require nu- 
merous joinmgs with glue or other ce- 
ment. I vay vin fir, because no other 
species of wood will succeed so wellin 
propagating the vibratory impulse of 
sound. Now.1 beg to assure J. 8. H. 
from the result of actual experiment in 
Mr. Weekes on the Mustcus Ventusorum.

this way, that the requisite exposure of 
the apparatus to atmespheric effecis, 
would speedily unglue the joinings of 
this outward case of the instrument; 
and, if not, the action of ‘the solar 
beams, dry winds, &c. would literally 
warp the machine to pieces. 
Much time and application to the 
subject induced me to think that the 
form I have suggested, (many having 
been tried,) taough not the most cle- 
gant, as J. S. H. has shown, is at Jeast 
the most effective: however, I do not 
hint that I consider it above improve-, 
ment. I will merely remark, that itis 
my opinion, if your correspondent 
couldsee the musicus uentusorum neatly 
constructed, he would not think it an 
inelegant instrument. ‘The proposition 
to-place the float-wheels wituin-side 
the outward machine, was tried in the 
course of the experiments I have al- 
luded to, and I am very sorry it did not 
answer equa: to their external situa- 
iion. J. S. H.’s remark atihe conclu- 
sion of his third paragraph,— thus the 
wheel will stand still,” is perfectly 
just. You, sir, I believe, are in posses- 
sion of theremedy. A sketch with some 
observations baving been forwarded 
during the month of July, I presume 
they came to band too late for the cur- 
rent number, though I doubt not you 
will do me the favour to insert them 
hereafter. ‘ 
The defect alluded to by J. S. H. 
actually occurred when the musicus 
ventusorum was constructing ; and, the 
drawings being made separately, one 
of them was nnfortunately mistaid, and 
not sent or incorporated with the origi- 
nal description, 
The propagation and improvement 
of practical science must give pleasure 
to every impartial and rational mind ; 
J. S. H. will therefore accept my un- 
feigned thanks for his friendly sugges- 
tions, whicn I hope he will not con- 
clude, from any of the foregoing obser- 
vaions, that Tundervalue.
