---- Rectory, Hereford.
_Mr. Lyte's Mode of Printing._--All persons who have experienced
disappointment in the printing of their positive pictures will feel obliged
by MR. LYTE'S suggestion as to the bath; but as the preparation of the
positive paper has also a great deal to say to the ultimate result, MR.
LYTE would confer an additional obligation if he gave the treatment he
adopts for this.
I have observed that the negative collodion picture exercises a good deal
of influence on the ultimate colour of the positive, and that different
collodion negatives will give different results in this respect, when the
paper and treatment with each has been precisely the same. Does this
correspond with other persons' experience?
