REVIEW. 
757 
It has been thought that the sheep-pox might prove to be a 
new preventive of small-pox in man; and to this end children of 
different ages have been submitted to inoculation,but the punc¬ 
tures were only followed by a little superficial irritation, without 
any pustular development or suppuration. After having re¬ 
peated the experiment several times with the same results, 
these children were afterwards vaccinated successfully. To 
make sure of the matter used in these experiments, some 
sheep were inoculated at the same time with the same virus, 
and which produced the usual successful effect on them. Other 
experiments have been tried by inoculating fowls of different 
species, neat cattle, horses, rabbits, dogs, and monkeys, but 
without effect. The inoculation of the smallpox of man in 
sheep has also been unsuccessful.

On reading this little book, big, however, with important 
facts, the mind reverts at once to some remarks in the 
review of the same work in the Lancet for September 6th, 
1862, which are so much to the purpose that we cannot 
resist reproducing one or two of them. 
The reviewer says, “ How often, not only in the army, 
but in almost every calling, is the tender frame of the young 
lad overtaxed;” and again, “ Dr. Aitkin may find that he 
has exerted a wider influence than he anticipated when he 
published his excellent and useful lecture.” These as¬ 
sertions, we will add, are daily verified by experience. 
“ Age,” says the author, “is only one of three most im¬ 
portant elements ; and when the bones of the skeleton are 
examined it will appear that up to the age of thirty years 
the skeleton framework of the body is still growing, and that 
the whole man is only arriving at maturity. Such a study 
ought to convince any one of the necessity of the great care
