altered since they left Bolton’s hands. As described by Dr. 
Shear the manuscript consists of six folio volumes bound in 
boards with morocco back. The paper is heavy hand-made 
with rough surface very suitable for water-colour illustrations, 
and they include 244 water-colour plates representing the 
plants mostly in their natural size. The volumes cover a 
period of eight years. * The first volume is dated 1784, and 
the note at the end of the sixth is dated January 5th, 1792. 
A comparison of the plates in the manuscript with those in 
the published work shows that all the species in the printed 
volumes are found in the manuscript volume and also a few 
not published. In the manuscript the species illustrated 
are all on separate plates, whereas in the printed volumes 
several small species, sometimes four, are combined on a 
single plate. In the manuscript the species illustrated are 
arranged in the order in which they were collected and drawn. 
When they were transferred to the copper plates for printing 
they were rearranged and renumbered.’ 
Dr. Shear also refers to the inclusion of notes not printed 
in the published work and the two following quotations 
may be reproduced here for the sake of their intimate Yorkshire 
associations : — 
AGARICUS RUBEUS, HIST. 36. 
Red Agaric. 
This new and beutiful species I gathered in company with 
my Friend, Mr. Paul Shackleton the Entimologist, in a little 
Wood at Shibden Hall near Halifax, October ye 29th, 1786. 
Gills in three series, transparent in some lights, and of a 
Ruby colour. Pileus looks like Pillow Fustin made of dark 
red Cotton. Stem tough solid crooked and near the root a 
little swell’d. No volva. I never met with it before or 
since. 
SPHAERIA MORI HIST. 120. f.i. 
Mulberry Sphaeria. 
Sph. fragiformis . 
This Sphaeria was brought me by Wm. Alexander, M.D., a 
most ingenious Botanist and steady Friend, who has ac- 
companied me in many of my most arduous and extensive 
Botanic rambles, has swormed the dreary precipices at 
Ingleborrow, Skiddow, yeGlydar, and Criby destillh, with a 
spirit and Resolution wh. Indicates a true Botanic Genius. 
The Sphaeria grew on the Bark of a fallen Maple Tree near 
his House in Halifax, — -. 
I have figured it as it appeared under magnifiers of two 
different powers.
