    1881.] In a short paper (17) the writer has previously urged the desirability of a uniform position for anatomical figures, and suggested that the head end should be always toward the left. As is stated above, while this seems to be most advantageous for unsymmetrical figures, the symmetrica] ones are more easily understood and compared in the position which is usual- ly given them. The obliquity of fig. 17 was necessary in order to show the Fissura hy- pocampai in its whole length. That such a position is undesirable, as a rule, may be inferred from the unwonted emphasis with which it was con- demned by the late Prof. Jeffries Wyman :— ‘ ‘ The photograph is from an oblique point of view, which I believe people will never learn to be a bad one. If the view had been full front, or full side, or full anything, it 'would have been better than this.”—The Ameri- can Naturalist, II, 52. Most of the figures are twice the diameter of the preparations, and, with the exception of figures 1 and 2, it should have been better to make the enlargement four or five diameters. Aside, however, from the greater expense which this would have involved, such a degree of enlargement would have rendered it not only possible but necessary to show certain de- tails of structure upon which my information is, at present, imperfect. All of the figures have been drawn from my own preparations by Miss G. D. Clements, B. S., at the time a student in the Natural Histoiy Course in Cornell University. Artists and anatomists who have undertaken to represent the details of encephalic structure understand the difficulties of the task, and will ad- mit that the omissions and inaccuracies to which attention is called in the descriptions are both few and unimportant compared witli the general thor- oughness of the work. Indeed, for all tlie deficiencies, I hold iii3'^self much more responsible than the artist, by whom some of the figures were drawn at least four times, twice upon stone. PL.\TE I. Fig. 1.—The dorsal aspect of the brain. Enlarged two diametere. Tlie general form and some of the fissures arc drawn from prep’s 288 and 289, the bisected brain of a white and Maltese 9 : IJ'it the fissures of the right hemisphere are derived from several different preparations. The Lohi olfactorii (L. ol.) are made somewhat too prominent, but there is considerable difference between cats in this respect, although much less than between dogs. The general features of the cerehdlum (cM.) are well shown. The Lobi later ales {L. (.) have only a fair jtroportion to the median lobe or ccrwis (Bffi.), instead of the preponderance which they have in the human brain. The lateiiil contortion which characterizes the caudal aspect of the vermis in adult cats (as shown in my paper, 10, 221, pi. i, fig. 1 and 2) does not affect the dorsal jiart. Of the metencephalon {mten.), and myelon {my.), the following features
