proved very useful; the bottom and sides are of one 
piece, the ends are soldered on, and four knobs at the 
bottom serve to reduce wear; the lid is made a good fit, 
and has two rolls of zine soldered on to serve as rests 
when it is used as a draining tray. A handle is placed 
at each end for convenience of lifting. We have these 
boxes made in different sizes—one, 8 inches long by 
4 wide and 6 deep, does for small monkeys, birds, rats, 
&c., a little larger size will take hands and feet, &c., and 
so on. These zinc boxes would also do very well for 
macerating in a running stream. 
A tank the size I have mentioned would be large enough 
for most institutions, as may be gathered from our having 
recently macerated in it the following animals at one 
time :—Full grown Nylghau, Tapir, two Greyhounds, 
large Mastiff, Indian Antelope, fairly large Ourang, 
young Gorilla, Spider Monkey, Galago, Douroucouli, 
large Python, Pelican, Duck, Sarras Crane, &c. 
Notwithstanding the great assistance warm water gives, 
-many animals take a surprisingly long time to macerate, 
which, like many other things, can only be done success- 
fully with much patience and probably after many failures. 
The horse skeleton in the Equestrian Group now in the 
Liverpool Museum, was macerated in the tank just 
described for six or seven months, although, unlike most 
horse skeletons, this one was not particularly greasy. 
I may, perhaps, having had a pretty large experience, 
reckoned by animals rather than years, advise any one 
intending to attempt maceration not to try young or rare 
beasts until they have had some experience with larger 
common ones.
