It may be that in particular cases particular modes of cultivation disfavour the host; or that the soil, climate or seasons do so; but overwhelming evidence exists to show that the principal causes of epidemics reside in circumstances which favor the spread, nutrition and reproduction of the pest, and the lesson to be learnt is, that precautions against the establishment of such favoring conditions must be sought.

Certain extremely aberrant Diptera, which, in consequence of the adoption of a parasitic mode of life, have undergone great structural modification, are further remarkable for their peculiar mode of reproduction, on account of which the families composing the group are often termed Pupipara.
Reproduction is mainly asexual, the females producing living young without the agency of a male.
Nevertheless, the function of reproduction is occasionally exercised by larvae.
In a letter to a friend at the Perkins Institution, dated May 17, 1889, she gives a reproduction from one of Hans Christian Andersen's stories, which I had read to her not long before.
The equable temperature of these cellars and their freedom from drought is one cause of their great success; to this must be added the natural virgin spawn, for by continually using spawn taken from mushroom-producing beds the potency for reproduction is weakened.
As already stated, there occur in the Hydromedusae two distinct types of person, the polyp and the medusa; and either of them is capable of non-sexual reproduction by budding, a process which may lead to the formation of colonies, composed of more or fewer individuals combined and connected together.
Protohydra is a marine genus characterized by the absence of tentacles, by a great similarity to Hydra in histological structure, and by reproduction by transverse fission.

It is in these parasitic forms that we meet with the method of reproduction by sporogony described above.
These first unscientific ideas of a genesis of the permanent objects of nature took as their pattern the process of organic reproduction and development, and this, not only because these objects were regarded as personalities, but also because this particular mode of becoming would most impress these early observers.
No specialized system of spermathecae, sperm reservoirs, and copulatory apparatus, as in Oligochaeta; development generally through a larval form; reproduction by budding also occurs.

For very refined work, however, the irregularities in the reproduction of the reseau may be studied by comparing the measures of the original reseau with the mean of corresponding measures of a number of photographed copies of it.
The non-sexua 1 reproduction takes the form of fission, budding or sporogony, the details of which are described below.
Nearly every possible method of reproduction occurs amongst the Hydromedusae.
In this way we may distinguish, first, vegetative reproduction, the result of discontinuous growth of the tissues and cell-layers of the body as a whole, leading to (I) fission, (2) autotomy, or (3) vegetative budding; secondly, germinal reproduction, the result of the reproductive activity of the archaeocytes or germinal tissue.
The casket was opened in 1906, at the instance of the emperor William II., and the draperies enclosing the body were temporarily removed to Berlin, with a view to the reproduction of similar cloth.

The most magnificent part of the exterior and indeed the finest polychrome monument in existence is the west façade, built of richlysculptured marble from the designs of Lorenzo Maitani of Siena, and divided into three gables with intervening pinnacles, closely resembling the front of Siena cathedral, of which it is a reproduction, with some improvements.
Those who believe the " Declaration " to be spurious argue that survivors remembered only one such document, that the Resolutions might easily be thought of as a declaration of independence, that Governor Martin in all probability had knowledge only of these and not of the alleged " Declaration," and that the dates of publication in the Raleigh and Charleston newspapers, and the politics of those papers, show that the Resolutions are authentic. In July 1905 there appeared in Collier's Weekly (New York) what purported to be a facsimile reproduction of a copy of the Cape Fear Mercury which was referred to by Governor Martin and which contained the " Declaration "; but this was proved a forgery.'

Paired processes on the eighth and ninth abdominal segments may be specialized as external organs of reproduction, but these are probably not appendages.
The larvae produced by this remarkable method (paedogenesis) of virgin-reproduction are hatched within the parent larva, and in some cases escape by the rupture of its body.
The calendar was the Syro-Macedonian, a solar, as distinct from the primitive lunar, calendar, which Roman influence disseminated throughout Syria; it was practically a reproduction of the Julian calendar.
About the same time, in a letter to a friend, in which she makes mention of her Southern home, she gives so close a reproduction from a poem by one of her favourite authors that I will give extracts from Helen's letter and from the poem itself:
The term " telephony " was first used by Philipp Reis of Friedrichsdorf, in a lecture delivered before the Physical Society of Frankfort in 1861.1 But, although this lecture and Reis's subsequent work received considerable notice, little progress was made until the subject was taken up between 1874 and 1876 by Alexander Graham Bell, a native of Edinburgh, then resident in Boston, Mass., U.S.A. Bell, like Reis, employed electricity for the reproduction of sounds; but he attacked the problem in a totally different manner.
This conception of,the plant as an aggregate or colony of independent vital units governing the nutrition, growth and reproduction of the whole cannot, however, be maintained.

The term Cryptogam is archaic, implying a hidden method of reproduction as compared with the obvious method represented by the flower of the Phanerogam; with the aid of a good microscope it is, however, easier to follow the process of fertilization.
Every plant is constrained to carry Out its functions of germination, growth, nutrition, reproduction, &c., between certain limits of temperature, and somewhere between the extremes of these limits each function finds ao optimum temperature at which the working of the living machinery is at its best, and, other things being equal, any great departure from this may induce pathological conditions; and many disasters are due to the failure to provide such suitable temperaturese.g.
