Excerpt from Introduction to Zoology, for the Use of SchoolsAs Zoological science is progressive, we must expect that, with an increased knowledge of the structure of different groups of animals, there will arise from time to time a necessity for corresponding changes in classification and nomenclature. During the last few years this has, in an especial degree, been the case with regard to the invertebrate animals Erroneous views respecting some of its groups have been corrected, much that was doubtful has been made clear, and affinities, previously unsuspected, have been revealed.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from The Screw Propeller

Excerpt from A Little Book About Rogers Fresh-Dug Dansville Trees

Excerpt from The Journal of Experimental Zoology, 1915, Vol. 19Linkage has been explained by Morgan on a chromosome basis, in accordance with the cytological evidence. It is assumed that gens occupy fixed positions, linearly arranged within the chromosome. In diploid groups each such linear series is represented by two homologous chromosomes, A and a, every locus in the one (a) corresponding to the same locus in its homologue (a). Before maturation homologous chromosomes become paired, side by side, and the members of each pair be come twisted about each other. At some of the points of con tact the two strands twist in two, as it were, moreover, the end of A fuses to the other end of a. As they lie opposed. Any gens that were in strand A but on different sides of a chiasma point will emerge in different strands because of the crossing - over, and hence will be segregated to different gametes. It is obvious that the closer together in the strand any two given gens lie, the less is the chance that in any given maturation a chiasma will occur between them, the chiasmas being distributed ao cording to chance. The basis of linkage is that two gens lie in the same chromosome so close together that in less than half the maturing germ cells a crossing-over takes place between them.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from The Significance of the Colon Count in Raw MilkThat coli-like organisms are present in soil has been shown by Johnson and Levine who found them more prevalent in soils upon which crops were growing than in absolutely fallow areas receiving soil treatment. Aerogenes-cloacae types were found to be the pre dominant coli - like forms in the soil.It is apparent that the B. Aerogenes type found in air may be derived from various sources, and it is not inconceivable that the organisms of this type found in market milk produced under clean conditions are the descendants of those introduced into the fresh milk in extremely small numbers by means of air contamination. It is also possible to contaminate milk with organisms of the B aerogenes type by using unsterilized utensils.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
