bis study of optics. 
When be writes the second chapter of the “ Optical Curiosities of 
Literature” he can add his own lucubrations as the most ridiculous 
specimen of the Cui-iosities of Optical Literature. 
I am happy to add that there are parts of Mr. Brakey’s paper in 
which I heartily concur. I will mention his remarks (p. 224) on the 
ignorance of some of the working opticians of the science of their art, 
of the why and wherefore of the formula ; and those on p. 229 on 
illumination and interpretation. These last cannot be too strongly 
impressed on the minds of all observers, whether expert or novices.

N.B. — It is not my province to notice the attack on Mr. Tolies ; 
I only wish to say that Mr. Tolies has not seen it, and it is not likely 
that he will for some weeks.

Cambridge, Mass., May 29, 1872. 
Dear Sir, — On page 234 of the Journal for May, 1872, I find a 
communication from Mr. F. H. Wenham in an unusually venomous 
strain. I wish him to separate my identity entirely from that of

“ wilful deception ” does not occur in any of my communications. 
Very truly yours, 
Edwin Bioknell.

ones, as they render unintelligible some of the sentences in which they 
appear.* 
I am, Sir, 
Your obedient servant,
