and expanded to 45 inches, bring the intersec~or to junction of pressure line 25, and distance line 45, we find upon the cut off line 8, the pressure 4, 4 pounds. The same pressureis required for any other pressure and distance. The interscctor operating upon the given pressure line for any distance throughout the length, the recluired pressure will be indicated upon the cut off llne. This table constructed upon a larger scale will admit of decimal and other subdivisions, giving the pressure sufficiently correct for prac'tical purposes. The pressures as noted upon the cut off line are the ordinates to a hyperbolic curve corresponding to that degree of expansion.
Ye Anatomic of ye _Engineere.* The Indian _Punch has the following :--Although an arch man, yet is he never forgetful of gravity; and though he damneth and blasteth more than any other man, he piqueth himself on being always correct in his terms : he is a dab at algebra, for which a Y Z is needful : he is a very ~oah at describing ares. Though he seeketh not after taverns he is conversant with sines, and payeth due attention to his cosines and sick Aunts. Even though not wealthy, he helpeth to establish many u bank. Ite, ever kind and hospitable, supplieth chairs for sleepers, and though addicted to rail is never forgetful of the tender: he is a dutiful subject and though often in hot water, ever payeth fit attention to the Governor. IIe is somewhat of an ornithologist, knoweth all about cranes and crows, kites, tumblers, and cocks for hengines, and moreover maketh wire ducks to aid his resonant steam eagles to fly. lie is also somewhat of an entomologist, understanding flies, crabs, worms, and such likes, and not above taking notice even of a cows ticks. Though partial to hydraulics he is not otherwise a rollicking man, yet is at home in high dressed attics, where he often maketh use of new mattocks in his area speculations. He is a peaceful man, though ~ell versed in triggernometry, and in the habi~ of making great use of switches in various ways. Ile is of levelling tendencies, yet sometimes wisheth he were monarch of all he surveyed, tie is the mosL progressive of mortals, axing his way through forests and picking it through rocks, and, paradoxical as it may seem, he opens a country by putting locks on the rivers and keys on the banks, lie is by no means a hater o' docks man, but well versed in dry dock trinal subjects, and would never desire to pull down the church unless it stood in the way of a railroad. He reverenceth the institutions of his country, because in them he recognizeth the mechanical powers. The Press he rightly re_~ardeth as the lever; the ten-pound voters as the small end of the wedge ; the Itouse of Lords as the inclined plane, and the Commons as the screw : the Army he eonceiveth to be both hammer and tongs combined, the Navy a series of pulleys, and country justices in general pumps. His affection for the constitution is unbounded, for he only regards it in the light of the common wheel. * From the London Builder, No. 816.
