Two plaster casts of Stigmarian trunks found at Dixon 

 Fold in making the railway from Manchester to Bolton, in 

 1837. It is a little doubtful whether Bowman's figures were 

 taken from the plaster casts or from the original trunks. In 

 figuring the plaster casts, Professor Williamson thus alludes 

 to them : — " On examining the trees discovered at Dixon 

 Fold it soon became obvious that the shaly materials of 

 which they were composed would give way, however care- 

 fully they might be protected from the weather. Hence an 

 Italian artist named Bally, well skilled in the art of making 

 moulds, was employed to obtain exact casts of the two most 

 important of the above trees." These casts are now in 

 the Manchester Museum.
