Dr. Maddox, on Photomicrography. 41 
vast edifice the microscopist raises by his patient research. 
"We cannot turn to the marvels of design arranged in the 
humblest microscopist's cabinet without desiring to have at 
hand some ready means of drafting from its stores a faithful 
recognition of its objects^ which^ although it may not supply 
a true significance of each part_, may yet determine its 
common value; or refrain, when we examine the cabinet, 
richly stored with the dust of primeval age, which the Divine 
Hand, when '^'^ moulding confusion to such perfect forms/^ 
marked with graceful symmetry and elaborate adornment in 
characters of exhaustless beauty, from wishing for some easy 
method by which their wonderful variety might find an 
adequate representation. 
Where can we look for this assistance if not in such plans 
as may diminish the labour of the draughtsman, and afford 
efficient means of moderately enlarging, diminishing, or 
multiplying the copy? Is it not to photomicrography, 
whether adopted on metal, stone, or glass — whether coloured 
or touched by the ^' burin^^ of the artist- — that our effort 
must be directed ? 
When the same labour, the same skill, have been given to 
this subject as fortunately have obtained for the microscope- 
objective and camera-lens, then may the present imperfect 
copies be replaced by others more correct, the errors reduced 
to a minimum, and the reward success. When a sure and 
simple plan for employing such a substance as a ready sen- 
, sitized collodion, which can be used wet without the constant 
trouble attached to the present process or the plates kept 
ready prepared, and an eligible mode of supplying a strongly 
actinic artificial illumination; when, in fact, the camera 
goes hand in hand with the microscope, and photomicro- 
graphy has found more favour than at present, then may we 
expect, from the combined application, truly useful results, 
and science render up more of her hidden treasures. 
This imperfect response to the wish of your President 
would be still more so without a due acknowledgment of the 
valuable hints and guidance given in the writings of those, 
whether at home or abroad, who have contributed to the 
literature of the subject, where all that relates to detail is 
fully stated., For much that appertains to these minutiae, 
also to various points connected with many of the negatives 
and objects, I must refer to a paper lately read before the 
London Photographic Society, and published in their ' Photo- 
graphic Journal ' for Dec. 15th ult. A candid criticism on 
the illustrations may render us more diligent students, and 
impart a new desire to thus study the minute organizations 
where beauty and variety solicit contemplation.
