supply of slides, all properly mounted in various ways, at tlie 

 wish of the subscribers, may be secured at a much less sum 

 than is spent in the postage, carriage, &c., of slides by ex- 

 change, to say nothing of the expensive process of purchasing 

 objects. Gentlemen who wish to subscribe to the above may 

 send their names and subscriptions as early as possible, the 

 number being limited, to begin from this date and end on the 

 10th of November, 1862. My object in the above propo- 

 sition is to be enabled to explore thoroughly the microscopic 

 productions of the fens, and all my time will be devoted to 

 the subject. — Wm. Wtxteii, Alderby, near Beccles. 



Transparent Carmine Injections. — 1 have found no difficulty 

 in remounting the transparent carmine injections, and did so 

 with all of the kind in my collection. If the broad slide is 

 the proper length — abo\'e three inches — your correspondent's 

 advice, in your last volume, may be followed by cutting with 

 the diamond to the necessary width and length; but I prefer 

 the remounting, particularly when the German slide is shorter 

 than three inches. — B. Wills Bichauuson, Dublin.
