Page 315 - The hyperbola is the locus of a point which moves so that the difference of its distances from two fixed points, called foci, is a constant. This constant is equal to the length of the transverse axis. In Fig. 2-16, F and F' are the foci, and line AB, which joins the vertices A and B, is the transverse axis.
Page 267 - Around the segmentai organs in the feet are peculiar cells richly supplied with tracheae, which appear to me to be similar to the fat bodies in insects. There are two glandular bodies in the feet in addition to the segmental organs. The more obvious features of the nervous system have been fully made out by previous observers, who have shown that it consists of large paired supraœsophageal ganglia connected with two widely separated ventral cords — stated by them not to be ganglionated.

Page 267 - ... median division of the body-cavity by longitudinal septa of transverse muscles. Each fully developed organ consists of three parts: (1) A dilated vesicle opening externally at the base of a foot. (2) A coiled glandular tube connected with this, and subdivided again into several minor divisions. (3) A short terminal portion opening at one extremity into the coiled tube (2) and at the other, as I believe, into the body-cavity.

Page 268 - A median nerve is given off from the posterior border of the supraoesophageal ganglion to the oesophagus, which probably forms a rudimentary sympathetic system. I believe also that I have found traces of a paired sympathetic system. The organ doubtfully spoken of by Mr. Moseley as a fat body, and by Grube as a lateral canal, is in reality a glandular tube, lined by beautiful columnar cells containing secretion globules, which opens by means of a non-glandular duct into the mouth.
Page 266 - The discovery clearly proves that the genus Peripatus, which is widely distributed over the globe, is the persisting remnant of what was probably a large group of forms, from which the present tracheate Arthropoda are descended. The affinities of Peripatus render any further light on its anatomy a matter of some interest ; and through the kindness of Mr. Moseley I have had an opportunity of making investigations on some...
Page 12 - In the case of the banded flints he exhibited and distinguished two kinds — one in which infiltration had taken place all round the outside, often a good test of the drift origin of certain fragments ; and the other in which a difference of texture, due generally to some included organism, had determined and limited the area over which infiltration had produced bands of colour. He pointed out that these differently coloured included portions, whether banded or not, affected the fracture, as they...
Page 268 - ... from normal Arthropoda and Annelida, viz. the absence of ganglia on the ventral cords, does not really exist. In other particulars, as in the amount of nerve cells in the ventral cords and the completeness of the commissural connections between the two cords, &c., the organisation of the nervous system of Peripatus ranks distinctly high.
