science from its beginning and in all its branches so related as to weave the story into a continu- ous narrative has been sadly lacking. Singer states that in order to lessen the bulk of his work he has omitted references and bibliog- raphies from its pages, but we may readily recognize in reading it that he has gone to original sources for its contents and that all the statements it contains are authoritative and can readily be verified. In the Preface Singer indicates that we may hope to see the work continued to a later date than Harvey’s time and also that the present work may yet be expanded so as to contain material necessarily excluded from a book of the size into which this is compressed, because from cover to cover this volume is all meat and splendidly served for our delectation and digestion. Singer divides the history of Anatomy into four great epochs or stages. The first is from the Greek period to 50 b .c ., comprising the Hippocratic period, Aristotle and the Alexan- drians. Although, as Singer says, “our anatom- ical tradition, like that of every other depart- ment of rational investigation, goes back to the Greeks,” yet before their time men groped at some ideas as to anatomical structure, as evinced by the drawings found in the homes of the cave dwellers, and the Egyptians and the The Evo lut ion of Ana to my , a Short Histo ry of Anat omi cal an d Phys iolo gica l Disc ove ry , Mesopotamians had quite distinct conceptions to Harve y .

There is a waning in development of anatomical science during enthusiasm for all save “useful knowledge” this great epoch in its history. We know of no and Singer shows how this so-called “practical” better description of the work of Vesalius and outlook proved disastrous to the progress of his followers, Realdus Columbus, Fallopius, science for many centuries. He refers to the Fabricius, and so forth.

The third epoch, from 1050 to 1250, is marked by the prominence of the Arabians in scientific matters. From the eighth to the thirteenth century the Arabians dominated in intellectual matters, and Avicenna, Hali Abbas, and Rhazes are the leading medical writers until the year 1500. Their works were disseminated throughout Europe by translations into Latin made by Constantine the African, Gerard of Cremona and many others of lesser note. During the thirteenth century occurred the develop- ment of the great universities of Italy, and with the opening of the fourteenth century human dissection first began to assume its proper importance in the study of anatomy. Singer goes very fully into the early history of human dis- section and the work done by Mondino, Achillini, and the early dissectors, including the artists, Leonardo da Vinci, Michael Angelo, Diirer and Raphael. He then gives descrip-
