Smith’s large and beautifully illustrated atlas contains the first clear description and illustration of neurofibromatosis, published 33 years before von Recklinghausen’s account of the disorder (see No. 4566). This disease, which affects the skin and nerves, is characterized by light brown dermal spots and fibrous tumors associated with tumors of nerve trunks and fibrous bone lesions. Measuring about 67.5 x 46 cm., this atlas has been called the largest book from the standpoint of format published in Ireland up to this time.
