G inches long and one-eighth inch dia- 

 meter. The slips (S) are two inches by 

 one inch in size, and have a hole five- 

 eighths inch in diameter bored through 

 the center. The centers of the holes are 

 to correspond with the axis of the tube 

 (T) when the apparatus is set up. Over 

 the hole in the lower slip a heavy piece 

 of blotting paper (P) is placed before 

 the tube (T) is put in position. A base- 

 board (B) five inches by two inches, of 

 the same material as the slips, which 

 are about one-eighth of an inch thick, 

 is fastened securely to the bottom of 

 the apparatus by milled head nuts (N.) 



This allows the whole apparatus to be 

 set securely on the edge or a tumbler. 

 If a tube (T^) the size of the upper tube 

 (T), the upper end of which is filled 

 with absorbent cotton, is run through 

 the base-board (B) so that the cotton 

 comes in contact with the lower surface 

 of the blotting paper, the filtrate will be 

 carried into the tumbler without wetting 

 the outside of the apparatus. Thoroughly 

 rinse the inside of the apparatus and 

 just before the urine (about 20cc.), which 

 has been previously shaken, is poured 

 into the tube (T) drop into it a clean 

 cover glass, so that it rests flat upon 

 the blotting paper. After pouring in the 

 urine, cover opening to keep out the 

 dust. Upon removing the cover glass 

 after the process is complete, the under 

 side of it (the upper when mounted) will 

 be found to be dirty; this may be 

 cleaned off by placing it upon a drop of 

 water upon a thin piece of paper and 

 carefully moving it about. The results 

 obtained vary with the quality of the 

 urine. Urine with abundant mucus does 

 not work so well; the best results are 

 obtained with thin urines of low density, 

 where it is desirable to search for casts. 

 Although this apparatus helps out 

 in many ways, it does not take the 

 place of the centrifuge which is now po 

 generally used.

Anatomical Atlas of Tschirch and Oesterle.* 



The Anatomischer Atlas of Tschirch 

 and Oesterle is an indispensable guide 

 in every botanical laboratory, not only 

 because of the careful drawings and 

 descriptions of crude drugs, but the 

 excellent account of foods in general 

 will be a great help in the botanical 

 laboratory. No other modern work has 

 given as many careful details of econo- 

 mic plants as this one. It also contains 

 a great deal of information on the devel- 

 opment of various parts of the plant 

 used as drugs or food. Lieferung 10 

 deals with Ergot, Secale cornutum, vari- 

 ous economic smuts. The seeds of 

 Lychsis Githago, Melampyrum arvense, 

 a full account of the seeds of Pisum 

 and Phaseolus multiflorus. For the testa 

 the terms palisade epidermis, I-cells, 

 nutrient layer are used. The use and 

 function of the nutrient layer is given. 

 Its function ceases when the seed is ripe. 

 Hyphae of fungi were often noted in 

 the hilar groove, but never in the 

 "tracheid island." The island resists 

 the entrance of fungi. In Pisuin the 

 water enters through the testa and not 

 the micropyle or hilar groove. An 

 equally full account is given of Pha- 

 seolus multiflorus. The term strophio- 

 lum is used for the arrillate processes 

 at one end of the hilum. The testa, in 

 the wider sense, is made up of palisade 

 epidermis, I-shaped cells followed by 

 parenchyma differentiated into three 

 parts. The inner integument consists of 

 an obliterated single brown wall (Haut). 

 This is followed by the perisperm 

 which may be obliterated or consists of 

 a single row of cells or several in the 

 radicular pouch. The cell-walls are 

 mucilaginous. There are also shorter 

 accounts of Ervum Lens, Phaseolus 

 vulgaris, Dolichos sinensis, Lablab vul- 

 garis, Soja hispida, Vicia Faba, V. 

 sativa, Lathyrus sa'tivus, and Cicer 

 arietinum. The remainder of the Liefer- 

 ung is devoted to amylum and continued 

 in the twelfth number. All of the more 

 common reserve starches are flgured 

 and described. Lieferung 12 is devoted 

 to mace, seed of flax, Rhiz. Valerianae, 

 Folia coca. Herb matae. A work of this 

 kind has long been needed and the 

 writers are doing botanical science a 

 great service.
