is it easy to probe the extent of his general interests and hobbies, which are and have been as wide and varied as his technical interests. But a caller a t his home a t Lewiston, below the Niagara escarpment and looking down at a spot on the river where commenced an old carry, may find himself regaled with a feast of historical and topographical lore on such topics as the history of the early French and English settlements and what constituted a desirable site for Indian villages; or to be shown furniture carpentered by “A. H.” from historic timbers salvaged from the demolition of some ancient and noted building in the village, or a handful of arrowheads that might rouse even Whitney’s envy. Always an active member of technical societies, he has served on the boards of the Electrochemical Society and the American Institute of Chemical Engineers. In 1922, the legislature of the State of New York passed a law requiring a state license as a condition for the practice of professional engineering. There

was much uneasiness at the time in respect of the motive, wisdom, and probable results of this requirement, and had the law been administered either on a political basis or in an inadequate’manner, events might have justified this uneasiness. Fortunately, its administration was placed in the hands of an extremely competent board; and the licensing of engineers in New York State has been an entire success and was rapidly accepted as being as desirable as licensing in medical and legal practice. A . H. Hooker was appointed to the original board as representing, geographically, western New York, and, technically, chemical engineering; has served continuously on the board since-a record he shares with one other member-and is now chairman. His heavy share in the board’s work has constituted an important service to the public, and a still more important one to his fellow engineers. F. A . LIDBURY

NOTES AND CORRESPONDENCE Burning Characteristics of Smokeless Powder Editor of Industrial and Engineering Chemistry: In the article by A. M. Ball [IND.ENG. CHEM.,23, 498-501 (1931) 1, a time-saving method of calculating explosion temperatures is presented, together with an interesting series of temperature calculations made by this method. It is admitted by the author that the chief value of such calculations is in giving useful relative results rather than reliable absolute values. In other words, the results are as good as the heat data from which they are calculated. Even aside from this consideration, however, the reliability of the temperature values themselves can be enhanced by correction of an error which, though not great, should be pointed out in the interests of mathematical accuracy and clear reasoning. Using the notation of the article referred to, if the sum of Q3 and Q4 is to be equated to Q. the heat liberated on complete oxidation of the powder in an oxygen-bomb calorimeter, then obviously 44 must equal the heat liberated on condensation of the water present in the “frozen” equilibrium mixture, plus the heat of oxidation of the hydrogen (to liquid water) and carbon monoxide. It may be noted in passing that the heat effect a t room temperature due to any shifting of the water-gas equilibrium is nil: CO

The primed quantities are those found after completion of the combustion process and the unprimed refer to the concentrations which satisfy the water-gas equilibrium a t the explosion temperature. It is evident that where the combustion is colnpleted in excess of oxygen,

Equation 7 becomes, then, = = 9i(CO) + 57.5[(Ha) - 1/z(HN03’)] - 29(CO) + 10.5[(HzO) + (Hz) - ‘/z(HNOa’)] + 40.2(HN03’) = SS(C0) 4-68[(H2) - ‘/a(HNOa’)] + 10.5(HzO) + 40.2(HNOa‘,)

(ia) This differs from the author’s Equation i a by the inclusion of thc term 10.5(H10). His values of Q 3 are thus too high. In the typical calculation given, 10.5(H~O)= 0.112 cal. Q3 = L:f C,dt = 1.129 - 0.112 = 1.017cal.

and

The temperature result calculated from this is about 200 degrees lower than that from the uncorrected value of Q 3 . . If all the nitrogen be converted to nitric acid on combustion of the powder in the oxygen-bomb calorimeter, then of course ‘/z(HXOa’) = (Nz) = ‘/z atom (N) in powder and Equation 7a may be expressed differently. However, no evidence is given for this complete conversion. It may be noted that Equation 7a may be expressed in the following manner also:

Q - Qs = 68[(CO)

+ (Hz)] + 10.5(HzO) + 6.2(HN03‘) ( i b )

This is only another way of expressing the zero heat effect a t room temperature of the water-gas reaction. It indicates that when the powder is exploded in a closed container, the heat liberated falls short of that liberated on combustion of the powder in excess of oxygen. The difference depends largely on the sum of the carbon monoxide and hydrogen concentrations. This sum is independent of the water-gas equilibrium and can be calculated very simply from the ultimate composition of the powder, for, since
