dissections as it is to care for a large model; and furthermore the 

 vault may be considered as large freezing microtome for cutting 

 cadavers and even for cutting serial sections on an ordinary microtome. 

 And last but not least we preserve cadavers not suitable for dissection 

 as well as of animals until we are prepared to make skeletons of them. 

 Before we decided to adopt cold-storage we obtained many valu- 

 able hints from Prof. Huntington of Columbia College, New York, who 

 had employed an apparatus similar to ours for a great length of 

 time. I am under many obligations to him for valuable recommend- 

 ations, yet our apparatus can be improved in a number of ways 

 the most important of which I believe to be the construction of two 

 vaults, one within the other; the inner vault to be surrounded com- 

 pletely with the cold brine and to be used for freezing the bodies. 

 The outer vault to be used for preserving purposes and to be kept 

 at 0" or slightly below. In this case the engine would be used to 

 cool the brine about the inner vault whenever necessary. Moreover, 

 the outer vault should be surrounded with a brick or stone wall as 

 the expansion and shrinkage of the wood is too great. This expansion 

 is very marked and causes destruction of the insulation and finally 

 of the whole vault. I should cover the floor with zinc or some metal 

 and have it drained. It is necessary to clean the vault about once 

 a year and the extensive thawing is very injurious to the floor.
