of Microscopy," and "Living Light" appear as the more scholarly, while "Tooth Truths" and "Famous Finds by Pharmacists" will appeal more to the highachoal student's delight in the Ripley "Believe It or Not" facts. There are serious typographical errors on pages 86, 114, and 198. More illustrative material would add to the attractiveness of the volume t o the layman, but as long as the price of one dollar is held, it will be impossible to expand in this direction.

fifth of the book an excellent outline is given of what is known and conjectured by leading investigators about the physiology of the lipids in both animals and plants. There are more typographical errors than usual in a reference text, but these do not comprise a serious factor in the value of the monograph. There is no index, but the table of contents is given in sufficient detail t o serve this purpose fairly satisfactorily for an advanced student. The mimeoprinting an one side of each page only is clear and neatly arranged. T X ~ U~rvansrrvo~ P r r r s a u a o w C. G. KING PrrTSBUPICH, PBNNSYLV*NI*
