like Malpighi and Swammerdam, but being a man of unusual 
patience and manual dextcrity, he accomplished notable 
results. His great quarto volume is, however, merely a de- 
scription of the figures, and lacks the insight of a trained 
anatomist. His skill as a dissector 
is far ahead of his knowledge of 
anatomy, and he becomes lost in 
the details of his subject. 
Extraordinary Quality of the 
Drawings.—A few figures will serve 
to illustrate the character of his 
work, but the reduced reproduc- 
tions which follow can not do justice 
to the copper plates of the original. 
Fig. 23 gives a view of the exter- 
nal appearance of the caterpillar 
which was dissected. When the 
skin was removed from the outside 
the muscles came into view, as 
shown in Fig. 24. This is a view 
from the ventral side of the animal. 
On the left side the more super- 
ficial muscles show, and on the 
right the next deeper layer. 
Fig. 25 shows his dissection of 
the nerves. In this figure the mus- 
cles are indicated in outline, and 
the distribution of nerves to partic- 
Wie we ee ular muscles is shown, 
Lyonet’s Monograph, Lyonet’s dissection of the head 
1790 is an extraordinary feat. The en- 
tire head is not more than a quarter of an inch in diam- 
eter, but in a series of seven dissections he shows all of the 
internal organs in the head. Fig. 26 shows two sketches
