Huygens, in his Systema saturnium (1659), describes a micrometer with which he determined the apparent diameters of the principal planets.
Neugebauer, " Systema venosum avium," Nov.
Ten years before, John Worlidge, one of his correspondents, and the author of the Systema Agriculturae (1669), observes, " Sheep fatten very well on turnips, which prove an excellent nourishment for them in hard winters when fodder is scarce; for they will not only eat the greens, but feed on the roots in the ground, and scoop them hollow even to the very skin.
Linnaeus in his Systema naturae (1735) grouped under the class Insecta all segmented animals with firm exoskeleton and jointed limbs - that is to say, the insects, centipedes, millipedes, crustaceans, spiders, scorpions and their allies.
Edition of the celebrated Systema Naturae.
Immediately on the completion of his Regne Animale in 1756, Brisson set about his Ornithologie, and it is only in the last two volumes of the latter that any reference is made to the tenth edition of the Systema Naturae, in which the binomial method was introduced.
It is certain that the first four volumes were written if not printed before that method was promulgated, and when the fame of Linnaeus as a zoologist rested on little more than the very meagre sixth edition of the Systema Naturae and the first edition of his Fauna Suecica.
Muller brought out at Nuremberg a German translation of the Systema Naturae, completing it in 1776 by a Supplement containing a list of animals thus described, which had hitherto been technically anonymous, with diagnoses and names on the Linnaean model.
Teenth Edition of the celebrated Systema Naturae, which obtained so wide a circulation that, in the comparative rarity of the original, the additions of this editor have been very frequently quoted, even by expert naturalists, as though they were the work of the author himself.
In 1827 Wagler brought out the first part of a Systema avium, in this form never completed, consisting of forty-nine detached monographs of as many genera, the species of which are most elaborately described.
After several minor notices that appeared in journals at various times, Des Murs in 1860 brought out at Paris his ambitious Traite general d'oologie ornithologique au point de vue de la classification, which contains (pp. 529-538) a " Systema Oologicum " as the final result of his labours.
In 1735 appeared the first edition of the Systema naturae of Linnaeus, in which the "Insecta" form a group equivalent to the Arthropoda of modern zoologists, and are divided into seven orders, whose names - Coleoptera, Diptera, Lepidoptera, &c., founded on the nature of the wings - have become firmly established.
C. Fabricius (Systema entomologica, 1775), and extended in France by G.
His chief dogmatic work, Systema locorum theologicorum (12 vols.
Each discovery in turn was, according to the prevailing custom, announced to the learned world under the veil of an anagram - removed, in the case of the first, by the publication, early in 1656, of the little tract De Saturni luna observatio nova; but retained, as regards the second, until 1659, when in the Systema Saturnium the varying appearances of the so-called "triple planet" were clearly explained as the phases of a ring inclined at an angle of 28° to the ecliptic. Huygens was also in 1656 the first effective observer of the Orion nebula; he delineated the bright region still known by his name, and detected the multiple character of its nuclear star.
AMPHIBIA, a zoological term originally employed by Linnaeus to denote a class of the Animal Kingdom comprising crocodiles, lizards and salamanders, snakes and Caeciliae, tortoises and turtles and frogs; to which, in the later editions of the Systema N aturae he added some groups of fishes.
His great work, the Systema naturae, ran through twelve editions during his lifetime (1st ed.
The order was founded by Linnaeus (Systema Naturae, 1 735), and is still recognized by Terzi.._.
In botany the custom followed by John Ray (1627-1705) in his Historia Plantarum and in other works was continued in 1760 by Linnaeus in his Systema Naturae.
Linnaeus, even in his latest publication, placed it in the genus Hirundo; but the interleaved and annotated copies of his Systema naturae in the Linnean Society's library show the species marked for separation and insertion in the Order Grallae - Pratincola trachelia being the name by which he had meant to designate it in any future edition.
An improved set was afterwards published in London (1770), as also the theory (Theoria lunae juxta systema Newtonianum, 1767) upon which the tables are based.
Focal length, he discovered the brightest of Saturn's satellites (Titan) in 1655, and in 1659 he published his Systema Saturnium, in which was given for the first time a true explanation of Saturn's ring, founded on observations made with the same instrument.
