Excerpt from Natural Science, Vol. 11: A Monthly Review of Scientific Progress, July-December 1897

We fail to find any evidence in this paper that the chemistry' of the crustacean pigments has been advanced beyond the old stage of solution and colour-change with reagents. What we want is isolation and purification before we can say that our knowledge of the subject has been largely increased.

However, in spite of these minor blemishes (and all new work must be imperfect), we welcome this paper and hope the author may continue her observations.
