    cal lectures on the * Principles and Practice of Medicine,'1 Bennett draws both large granular cells with or without a nucleus, and small bodies invariably without a nucleus, which latter are entirely like Drysdale's corpuscles. Fig. 172 on page 172 shows very distinctly Drysdale's corpuscles, after addi- tion of acetic acid [the italics are Dr. Garrigues'] without nucleus. The text describes them as ' pale, round, and oval corpuscles, the outline of which becomes stronger on the addition of acetic acid.' 2 Notice the construction of this paragraph. The reader will get the impression, and it seems to be intended that he should, that the same cell is referred to in the drawing at page 91, and the one on page 172. It reads, Bennett draws both large granular cells with or withotit a nucleus, and small bodies invariably without a nucleus, which latter axe entirely like Drysdale's corpuscles. Fig. 172 shows Drysdale's cor- puscles after addition of acetic acid. What could the reader infer from this, but that Bennett had drawn and described the ovarian cell, and had used the acetic acid test as Dr. Garrigues has asserted ? The para- graph is entirely misleading, and is well calculated to de- ceive. The drawing on page 91 has no connection whatever with that on page 172, and it will be found that they refer to two entirely distinct varieties of cells. To understand the matter clearly, the paragraph must be separated. The first part of it refers to a drawing on page 91. In regard to this, Dr. Garrigues says, Bennett draws both large granular cells with or without a nucleus, and small bodies invariably without a nucleus, which latter are entirely like Drysdale's corpuscles. But how does he know that they are entirely like Drysdale's corpuscles ? Bennett does not describe them, nor even allude to them, certainly he never applied a test to them. Therefore, it is impossible to say what they were. Dr. Garrigues offers no proof, it is a mere assertion. The fact is simply this : Bennett gave a drawing of some 1 Second edition, New York, 1858, p. 91, Fig. 70.
