I have tried benzine, turpentine and many other things, but 
nothing seems so expeditious and cleanly as the mixture 
recommended, as it frees the slides from grease, which has to be 
done after using benzine or turpentine. 
I think perhaps I might say there is a risk in leaving the covers 
in the bottle of spirit and potash too long. I should fear an 
injurious effect of the potash on the glass, but this has not 
happened to me, though I have left them uncleaned for a long 
time after being removed from the slides. 
*** Several papers with the rest of the Proceedings are 
unavoidably held over. These will appear with the illustrative 
plates in a fifth part, concluding the first volume, and which it is 
expected will be issued almost immediately.
