[8] "At an early period the form of the ovisacs is usually elliptical, and their size extremely minute,--their long diameter measuring in the ox no more than 1/562 of an inch, so that a cubic inch would contain nearly two hundred millions of them. They are _at this time_ quite distinct from the _stroma_ of the ovarium; this forms a cavity in which they are loosely embedded." [9] Coleridge, p. 56. [10] "All vegetables," says Sharon Turner, "from that pettiness which escapes our natural sight, to that magnitude which we feel to be gigantic, have these properties in common with all animals--organization; an interior power of progressive growth, a principle of life, with many phenomena that resemble irritability, excitability, and susceptibility, and a self-reproductive and multiplying faculty."--_Sharon Turner's Sacred History._ [11] "Plants highly sensitive to light are those of the leguminous, or Pea kind. They always close up in the evening and clasp their two upper surfaces together, presenting only their backs to the air. Plants of pinnated leaves, as the Tansy, are more sensible than these to the effects of light. They fold up when light is too strong, as in Robinia; it produces the same effect as want of light. Its leaves close up, apparently, because they are receiving too much. So they do if a hot iron be brought near them. They contract as if to avoid the heat. Sensitive plants, and those of the Oxalis Lent. are so sensitive that the least motion, even a breath of air, will make them close."--_Sir J. Smith._ "The vitality of plants seems to depend upon the existence of an irritability, which although far inferior to that of animals, is nevertheless of an analogous character."--_Lindley's Introduction to Botany._ [12] Provincial Medical and Surgical Journal.

"If we examine the Cow Pox and the Small Pox microscopically, as I have done very carefully in every stage, we find that the essential character consists of a number of minute cells, not exceeding the 10,000th part of an inch in diameter, being about one-fourth smaller than the globules of the blood, containing _within their circumference many still more minute nuclei, and presenting_ beyond their circumference bud-like cells of the same size and character as those contained within the circle. They exactly resemble in everything except the size, the globules of the yeast plant, the Torula Cerevesiae. Now if we examine more circumstantially the analogies of what I would call the Torula Variolae with the Torula Cerevesiae, we observe the following corresponding facts.
