Frozen sections of a child
Thomas Dwight, Instructor in Topographical Anatomy and Histology, made these sections of a three-year-old child for use in his lectures at the Medical School in 1880-1881 and were some of the first frozen sections in use in this country. The plates are life-size. As part of the preface, Dwight includes his directions for making such specimens.
First, be very sure that the body, or part, to be frozen is in precisely the position you desire, and that there are no folds or indentations in the skin. I always use natural cold when possible. Weather much about zero (Fahrenheit) is unsatisfactory; but if the part is thoroughly chilled by several days' exposure to a pretty low temperature, a night of 10? may possibly finish it. Salt and ice, or snow, no doubt, will answer the purpose, but much time and patience are required
