necessarily restricted to the consideration of them
Piles" of the instruments TO be furnished
We find thrtytwo s'sping balances Of which are
admirably constructed on that principle but consider them
liable TO these objections l The want Of the requisite
sibiy 10 fractional weight under the halounce d.
visions of weight ID The want Of dsnciness the ready
indication to the eye Of the variations Of weight the gradu
aed scale, and their consequent liability and 3d. Tin
the most Of them, the great of from friction
We find twenty eight bent rer Tor pendulua) baia-
of which fine exhibitions Of mechanical genius
They all Of them liable 10 these objections st Too great
oscillation vibration for ready and 3D. Where the
attempt made remedy that objection the expense
of accuracy and dsincness 10 the eye Of the variations Of
weight
We find models of balances with connected or attach
ed weghts Of sixteen half They liable these
objections: Isl. The liability from friction the
change Of position of the weights in their and ID The

ty TO accident.
We Of the opinion that the balance called the
" Roman balance is the best adapted the particular pur-
pose and service in view Among the number Of samples
which find constructed this principle the which
think the most eligible is that marked No 90 rs H. & Da
Wis having single sliding weight mot suspended brass
beam, turning hardened points, the weight falling into half
notchcs with open scale Tor ish) above We sug

eligible models this principle, the next estimation
is that marked No 49, Fairbanks patent to which may b.
added No 8, [Benamin Morrison both of which seem un
wedy, and in the latter the adjusting weight the end
the beam is Objectionable for the service in view.
We also consider the balance called the iriI
scas with weights and open scales top eligible ant
the best sample Of these, esmaon that marked No
