Mr. C. Baker's New Catalogue. — Mr. Charles Baker 

 has sent out his new catalogue, which is increased in size 

 by about twenty pages. It contains particulars of his 

 latest instruments, such as the R.M.S. 1*27 microscope, 

 the D.P.H. Nos. 1 and 2, the Diagnostic, and the Planta- 

 tion microscopes. The newest pattern microtomes are 

 also included. The list of stains, mounting media, and 

 other accessories, is exceptionally complete and well ar- 

 ranged. Two or three pages are devoted to pond-life ap- 

 paratus, but the extra pages are mainly taken up with lists 

 of microscopic slides, arranged mostly in series at a mod- 

 erate price, though the price of individual specimens 

 seems rather higher that usual. The lists of bacteriolog- 

 ical and diatomaceous slides call for specialnotice.

 other students. Recognizing this, Messrs. Beck, by lay- 

 ing down new plans for displacing hand labor by machin- 

 ery in accordance with the practice of the day, have been 

 able to put upon the market a new stand in which sound 

 workmanship is combined with cheapneas. The stand fol- 

 lows largely the Continental model, but is sold at a con- 

 siderably lower figure than any similar Continental stand 

 known to us. The essential features are as follows : — 

 The stand is of the horse-shoe form, but the central pillar 

 is placed farther forward under the stage so as to give 

 greater facility when the microscope is in a horizontal po- 

 sition. The base itself actually rests on three inserted 

 cork pads, which not only give steadiness, but prevent 

 any possibility of scratching the table. The coarse ad- 

 justment is by spiral rack and pinion, whilst the fine ad-
