or bound up with text-books of anatomy. J. REMMELIN
resumed the method, which was formerly practised, of showing
the muscular layers and the viscera by means of pictures
pasted and superimposed on one another ;* a similar practice
was adopted by CLOPTON HAVERS. We owe some excellent
anatomical plates, especially on the distribution of the
nerves, to the painter PiETRO DA CORTONA; the vignette
on the title-page of the edition of 1741 represents the transfusion
of blood. GERARD DE LAIRESSE made the drawings
for the anatomical text-book of G. BiDLOO. The following
were intended chiefly for artists;—the anatomical work of
B. GENGA with the drawings of C. ERRARDS ; the Anatomia
dei pittori of CARLO CESIO, which appeared also in a
German translation; the representation of the muscles of
the body, designed by MARTINEZ the Spanish anatomist
and painter, and remarkable for its faultless proportions ;
the plates of ERCOLE LELLI ; and others. The copper plates
too, which adorned the anatomical writings of W CHESEL-
DEN and D. SANTORINI were conspicuous for their high
artistic value : the latter were held by MORGAGNI to be of
supreme merit. The introduction of coloured drawings of
anatomical subjects constituted a further advance; by this
method the arteries, veins, nerves and different organs
could be more sharply distinguished. This method was first
employed in the wood-cuts with which C. ASELLI enriched
his work upon the lacteal vessels. In the beginning of the
18th century J. C. LE BLON, the miniature-painter, made the
first attempt to produce coloured etchings; in 1721 he
published the first sheet illustrative of anatomy which had
been prepared by this method. But the new invention of
tinted copper engraving became more widely known and
was made use of for anatomical representation first by
JAN LADMIRAL, who provided several treatises of the
anatomists B. S. ALBINUS and F. RUYSCH with illustrations
by this process, and by J. F. GAUTIER D'AGOTY who
made use chiefly of the anatomical preparations of
