The only disadvantage of this method was that of not admitting of binocular vision ; otherwise its simplicity, cheapness, and great facility of adjustment, render it far preferable to the others, while its effects are fully equal to theirs. It answers, moreover, equally well by day- or lamp-light, and does not require a condenser to be used.

That results most important to agriculture, to commerce, and to the sanitary condition of mankind may be reached, is no longer problematical. It may be regarded as one of the certainties of future progress. But these results must be based upon the comparison and discussion of a wide range of observation. Much is to be hoped in this respect from the system of observations organized by the Smithsonian Institution in this...
