58 REVIEW. 
biology and even in pathology as we have seen put forward 
of late years. As regards pathological relations in man, we 
are building upon a very uncertain basis if we rest upon the 
distinction of germinal layers, since it is, as Professor Stricker 
remarks, still doubtful whether the laminz of the mammalian 
ovum correspond (especially the middle) with the three dis- 
tinguished by Remak in the fowl’s embryo. And yet we 
have had whole classes of new formations and special types 
of disease founded upon the distinctness of the layers of 
Remak. 
This chapter has been looked for with some interest on 
this ground also—that it was to contain the omitted or 
deferred theme of striated muscle; and Professor Stricker 
has redeemed his promise by giving a short sketch, partly 
descriptive, partly critical, of the subject. The descriptive 
portion would have been made much clearer by figures, and 
this is also true of the critical portion, but the latter suffers 
under the more serious, though quite unavoidable defect of 
failing to take into account the researches, since published, of 
Engelmann and Schafer, since these have given a new aspect 
to the question in dispute. In fact, the “commotion in the 
doctrine of muscle,’? which induced the editor to defer the 
consideration of this subject as long as possible, can hardly 
be said to have subsided in time to make a completely satis- 
factory article at all possible. 
We must, in conclusion, congratulate the translator upon 
the successful completion of his arduous task, and as we 
have in the former volumes not always agreed with his 
interpretation of some of the crabbed German idioms, we may 
also be allowed to bear our tribute to the care with which 
this volume has been edited and translated. It has also the 
advantage of a very full and excellent index, which strikes us 
as being, in plan and execution, decidedly superior to that in 
the German edition.
