Hence we may see how necessary it is that in all important controversies we should predefine the terms negatively, that is, exclude and preclude all that is not meant by them; and then the positive meaning, that is, what is meant by them, will be the easy result,the post-definition, which is at once the real definition and impletion, the circumference and the area.

But this identical area, from a little below 60° to the pole, is that occupied by the snow-caps of Mars, and over the whole of it the winter temperature must be far lower than the earth-minimum of-88°F.

The camp, when pitched, covered a large area of ground.

The catechumens filled several rows of pews in the front of the spacious area of the building, and, when they rose in a body to make profession of their faith, the scene is described as having been most impressive.

The total pressure required to burst this shell would be the area exposed times the pressure.

Consequently, the most important point in the investigation, namely, the area acted upon by the reflected radiant heat, cannot be accurately determined.

It should be observed that the area thus stated is 0.011 less than the total foreshortened superficies of the ninety-six mirrors if sufficiently wide to come in perfect contact at the vertices.

Agreeably to the dimensions already specified, the area of the 10-inch heater acted upon by the reflected solar rays is 331.65 square inches, the area of the 20-inch heater being 673.9 square inches.

The area of a sphere whose radius is equal to the earth's distance from the sun in aphelion being to the sun's area as 218.1² to 1, while the reflecter of the solar pyrometer intercepts a sunbeam of 3,130 square inches section, it follows that the reflector will receive the radiant heat developed by 3,130 / 218.1² = 0.0658 square inch of the solar surface.

Hence, as the 10-inch heater presents an area of 331.65 square inches, we establish the fact that the reflected solar rays, acting on the same, are diffused in the ratio of 331.65 to 0.0658, or 331.65 / 0.0658 = 5,040 to 1; the diffusion of the rays acting on the 20-inch heater being as 673.9 to 0.0658, or 673.9 / 0.0658 = 10,241 to 1.

The amount of pollen was determined by exposing slips of glass, each having an area of a square centimeter, and coated with a sticky mixture of glycerine, water, proof spirit, and a little carbolic acid.

(i.e., that one house out of every 244 was attacked by small-pox in the ordinary way), and that the area inclosed by a circle having a radius of one mile round the spot where the hospital was subsequently established (called in the report the "special area") was, as a matter of fact, rather more free from small-pox than the rest of the district.

After the establishment of the hospital in March, 1877, the amount of small-pox in the "special area" round the hospital very notably increased, as is shown by the table by Mr. Power, given below.

Probably there are few observant persons of rural habits who cannot call to mind one or another still autumn morning, when from a cloudless, though perhaps hazy, sky, they have noted, over a wide area, steady descent of countless spider webs, many of them well-nigh perfect in all details of their construction.

CHICAGO (1,700), the metropolis of Illinois, in the NE. of the State, on the SW. shore of Lake Michigan, is the second city in the Union; its unparalleled growth, dating only from 1837in 1832 a mere log-fort, and now covering an area of 180 sq. m., being 21 m. in length and 10 m. in breadthis due to its matchless facilities for communication.

EXMOOR, an elevated stretch of vale and moorland in the SW. of Somerset, NE. of Devonshire; has an area of over 100 sq. m., 25 of which are covered with forest.
