doptera themselves, rather than obtain them by pm'chase or exchange, 

 to do the same. I may perhaps as well say, to mitigate the effect of 

 my observations as to the weather met with in Glen Tilt, that it does 

 not always rain in the Highlands. I have had three holidays there 

 and two out of the three were fine. — G. H. Conquest ; 10, Meteor

Optical Instruments. — We have recently received two catalogues 

 from E. Leitz, optical instrument makers, of Wetzlar, London, &c., 

 those dealing with " Photomicrographic Apparatus," and " Projection 

 Apparatus and Drawing Appliances involving the Principle of Pro- 

 jection." These catalogues are two out of nine. The name of Leitz 

 is now, of course, well known as that of a firm of first-class optical 

 instrument makers, and anyone in need of a microscope, projection 

 apparatus, photomicrographic apparatus, or anything connected with 

 such things, should call at 9, Oxford Street, or examine the catalogues. 

 These latter are really more than simply price lists, as they contain 

 excellent illustrations of many of the instruments, and form something 

 of a text-book in connection with them. As regards photomicrographic 

 apparatus (Catalogue 43 G), we like very much the vertical method of 

 working with camera and microscope, and some of the instruments 

 figured seem very compact and convenient. There are at the end of the 

 catalogue two plates of photomicrographs which every photographer 

 seeing them will like to possess, the clearness of detail being par- 

 ticularly fine. Another publication of this firm is a fully illustrated 

 pamphlet of forty-two pages on "The Microscope and Some Hints 

 on How to Use it," which is excellent, though not intended quite for 

 the beginner in microscope-work, with the exception of the general 

 hints at the end. The firm offer the use of electros of illustrations 

 to authors. — W. J. Lucas.
